Optional ScreensMicro-Orifices® must be used with ex-tremely clean fluids (filtered to .03 mi-crons). Otherwise, there is a high probabil-ity of clogging the orifice with solid par-ticles. Even with clean fluids, there is alsothe possibility of introducing contaminantsduring assembly of the fluid system. Tominimize the possibility of clogging smallorifices, it is recommended that screens beinstalled on the upstream and downstreamsides of the orifice, to protect against han-dling contamination.
Fifteen micron screens are normally usedwith Micro-Orifices®, to minimize con-tamination that occurs during handling orassembly. Screen material is stainless steel.
Ordering InformationIdentify the part number of Micro-Orifices®
using the complete detail on the chart atright. See examples also.
For orifice assemblies without optionalscreens, use the base number only. Forassemblies that include screens, add thesuffixes shown in the table. Both inlet andoutlet screens are rated for 15 microns.

Pressure Snubbers
DescriptionA simple in-line element called a pressuresnubber is used to reduce the rate of flowof fluids into pressure instruments and con-trols. A small orifice in an adapter fittingdampens shock and fluctuating pressureeffects by limiting the rate at which flowenters. The smaller the orifice, the greateris the dampening effect.
The proper orifice size for any applicationdepends upon the size of the pressurizedchamber, the viscosity of the fluid and therequired response time of the system.
Orifice sizes from .004" diameter to .020"diameter are available. In general, largeinstrument chambers require large floworifices. Viscous fluids require larger floworifices than low viscosity fluids. Gasesgenerally require small orifices.
Specifications• Maximum Operating Pressure

• Fluid Media – Air, Water Gases andLiquids compatible with materials ofconstruction.
Dimensions
ApplicationsPressure snubbers are used as in-line ele-ments to reduce rapid pressure fluctuationsin the following types of components:
• Pressure Gages
• Pressure Measuring Instruments
• Air Piloted Valves
• Hydraulic Piloted Valves
They can also be used to control the flowrate of fluid delivered to:
• Air Cylinders
• Hydraulic Cylinders
• Fluid Actuators
See illustrations for typical applications.
A pressure gage equipped with a snubber willrespond more slowly to pressure changes than agage without a snubber. This slowed responsedampens pressure spikes caused by valves andpumps.
When valve opens the pressure in the pilot portincreases slowly. In the case of an air loadedpressure regulator with a snubber, the output alsoincreases gradually rather than suddenly.
Pressure measuring instruments are protectedfrom surges when equipped with a snubber. Highfrequency pressure spikes are dampened by thesmall orifice in the pressure snubber.
Ordering InformationTo order pressure snubbers, indicate quan-tity and obtain part number from the chart.
Pressure snubber adapts to pressure gage, instru-ment or control element with 1/8", 1/4" or 1/2"NPT connection.
After a valve opens, the pressure in an instrumentor control device builds more slowly whenequipped with a pressure snubber.
Operation
Pressure snubbers are in-line components whichreduce the rate of fluid flow to a gage, instrumentor control element and thus dampen shock andfluctuating pressure effects.

What To Do To ImproveMeasurement AccuracyIn many applications, errors of ±10% inflow rate are unimportant. In this case,corrections for 1) standard conditions, 2)barometric pressure and 3) temperatureare not required.
1. Definition of Standard ConditionsThe data on pages 16-18 is for standardconditions of 70ºF and 14.7 psia. To rec-oncile data taken from volumetric instru-ments which are referenced to differentstandard conditions, use the followingformula:
Qs = Qm x Pm x TS
Qm = measured volumetric flow (SCFH)or (SLPM).
Qs = volumetric flow corrected to 70ºFand 14.7 psia.
Pm = standard barometric pressure refer-enced by manufacturer (psia). This is gen-erally 14.7 psia.
Fundamentals of Flow Measurement
The Standard Cubic Foot
Volumetric FlowThe flow of gases is traditionally measuredin volumetric units such as cubic feet, li-ters or cubic centimeters. However, sincegases are compressible fluids, the totalmass contained in a given volume varieswith both the temperature and pressure ofthe gas. To provide a meaningful referencefor volumetric flow measurements, a"standard" set of conditions are defined fortemperature and pressure of the gas.
Unfortunately, the definition of standardconditions varies slightly in technicaldisciplines and industry groups. Standardtemperature ranges from 32 to 70ºF (0 to20ºC). Standard pressure is generallyaverage atmospheric pressure at sea-level,14.7 psia.
Standard ConditionsFor the data presented in the charts onpages 16-18, standard conditions are 70°Fand 14.7 psia. For data points measuredby O'Keefe Controls Co., the same stan-dard conditions are used.
GAS FLOW MEASUREMENT
A mass flowmeter measures flow accurately andrelatively independent of barometric pressure.The unit shown above is used to obtain the data forcalibrated orifices.
Factors to ConsiderIn comparing volumetric flow measure-ments taken at different locations andwith different measuring equipment,the following factors should be consid-ered:
• Definition of Standard ConditionsBetween 32ºF and 70ºF, the standardconditions can vary up to 8%.
• Temperature of the GasA 10ºF deviation causes about 1%error in a rotameter reading. Moreor less deviation occurs in other typeflow measuring instruments. The de-viations are predictable and the flowmeasurement is correctable.
• Barometric PressureNormal atmospheric pressure varia-tions of ±1/2" Hg. can cause morethan 1% error in rotameters. Altitudeis also an important factor, since thebarometric pressure decreases rap-idly with increasing altitude. At anelevation of 2,000 ft. above sea level,rotameter scale readings are in errorby 3-1/2%. These errors can be cor-rected quite easily with predictablecorrection factors, and accurateknowledge of barometric pressure.
14.7 492
Ps = standard barometric pressure = 14.7 psia.Tm = Standard absolute temperature refer-enced by manufacturer (ºRankine).Ts = standard absolute temperature = 530ºR.For Example:A mass flowmeter manufacturer uses thefollowing standard conditions:14.7 psia, 32°F (492°R)To convert to standard conditions of 70ºF(530ºR) and 14.7 psia, apply the following:
QS = Qm x Pm x TS = Qm x 14.7 x 530
= 1.077 Qm
The volumetric flow QS is larger than Qmby 7.7%. Consult the manufacturer of yourflow measuring equipment to insure thatyou know exactly the standard conditionswhich apply to your equipment.
2. Temperature EffectsConsult your instrument manufacturer fortemperature correction factors. There aretwo temperature considerations.1. Effect of ambient temperature on the
flow measuring instrument2. Effect of gas temperature on the flow
measuring instrument
3. Barometric Pressure EffectsConsult your instrument manufacturer forpressure correction factors. There are twopressure considerations.1. Effect of barometric pressure on the
flow measuring instrument2. Effect of gas pressure on the flow mea-
suring instrument

4. Other Orifice Sizes Air FlowTo calculate the required diameter of anorifice that is not included in the charts onpages 16-17 use the following formula.The equations are based on data taken forthe size no. 60 (.060" dia.) orifice.
QL dL = .060 Q60
in. dia.
Where:dL = diameter of the unknown orifice.QL = flow through the unknown orifice.Q60 = flow from chart on pages 16-17.
EXAMPLE: (data from page 17)At supply pressure of 50 psig and outlet atstandard conditions,
Q60 = 87.4 SLPM (from chart)Let:QL = 600 SLPM @ 50 psig
600 dL = .060 87.4
= .157 in. dia.
Water FlowUsing the CV method for liquid flow, andusing measured CV data we can derive thefollowing formula to calculate requiredorifice sizes.
1 QL dL =
22.5 ∆P
Where:dL = diameter of unknown orifice (in.)QL = required flow (gpm)
EXAMPLE:Flow rate required =.5 GPM @ ∆P = 1.0 psi
1 .5 dL =
22.5 1 = .149" dia.
Also, to obtain the CV
QL .5
CVL = ∆P = 1

Low Pressure ExtrapolationTo calculate flow rates at pressures lowerthan those on the charts, use the followingformula.
QLP = Q5 PLP
2 + 29.4 PLP
13.12
QLP = Flow at the low pressure (below 5 psig.)Q5 = Chart flow reading at 5 psig.PLP = Low pressure in psig.
EXAMPLE:To calculate the flow at a supply pressureof 0.5 psig. for the No. 16 metal orifice.
QLP = 3.26 0.52 + 29.4 (.5) = 0.96 SCFH 13.12
(from chart)
3. Temperature Effects Air FlowThe flow of gases through an orifice var-ies inversely as the absolute temperature.As the gas temperature rises and the gasdensity decreases, the mass flow rate alsodecreases.
To extend the chart data on pages 16, 17for air flow, use the following formula.
TS
QT = QS TT
Where:TS = standard absolute temperature °R (°R = 460 + °F).TT = non standard absolute temperature °R.QS = flow from chart at 70°F = 530°R.QT = flow at a different temperature.
EXAMPLE:At 70°F and an inlet pressure of 25 psigthe No. 60 (.060" dia.) orifice has a flowrate of 55 SLPM (see page 17). Undersimilar conditions, the air flow rate at300°F is
530 QT
= 52.8 760 = 44.09 SLPM
1. Specific Gravity Other GasesTo convert air flow from chart to anothergas flow.
Flow (gas) = Flow (air) / S.G. (gas)
EXAMPLE:To obtain flow rate for helium when airflow is 5 SCFH
Flow (Helium) = Flow (air) / .138
= 5 / .371 = 13.48 SCFH
S.G. = specific gravity of gas relative to airS.G. = .138 for Helium
Extending Orifice Flow DataEXTRAPOLATION
2. Pressure – Air Flow High Pressure ExtrapolationTo calculate flow rates at pressures higherthan those on the charts, use the follow-ing formula.
QHP = Q80 x PHP + 14.7
94.7
QHP = Flow at elevated pressure (above 80 psig.).Q80 = Chart flow reading at 80 psig.PHP = Elevated pressure in psig.
EXAMPLE:To calculate the flow for the No. 16 metalorifice at 150 psig supply pressure.
QHP = 17.99 x 150 + 14.7 = 31.15 SCFH 94.7

Test ProceduresA. Rotameters - Gas Flow
Rotameters for measurement of air or othergas flows must be used for the conditionsfor which they are calibrated. Typically theyare calibrated for the following:
• Air Flow
• Outlet Conditions - 14.7 psig @ 70ºF
Rotameters can be calibrated for other gasflows or other outlet pressure conditions.Manufacturers also provide graphs or tablesfor correction of measured data when con-ditions vary from the calibration conditions.
When using rotameters calibrated for stan-dard outlet conditions use the test proceduresshown below.
Positive Supply Pressure
Vacuum Source
B. Mass Flowmeters - Gas Flow
Mass flowmeters are generally insensitiveto gas pressure or barometric pressure con-ditions. Consequently their location in thetest circuit is not critical. Consult your in-strument manufacturer for recommendedtest procedures.
C. Instrument Accuracy - Gas Flow
The three variables to be measured in gasflow applications are:
• Pressure• Temperature• Flow Rate
The accuracy of the flow measurement of agas through an orifice is limited by the com-bined accuracy of the instruments used inthe measurement. Expected accuracy of agas flow measurement is generally in therange of 1 to 20%. 1% accuracy can only beachieved with high quality instruments.

Calibrated OrificesWATER OR AIR FLOW
Air FlowFor flow standards or other critical uses,O'Keefe Controls Co. can provide measuredair flow data for any of the standard preci-sion orifice products. This optional serviceis available at a nominal charge and can beprovided for pressure or vacuum flow con-ditions in the standard ranges listed below.A calibration sheet with measured data isprovided for each orifice (see sample below).
Data is obtained using a digital mass flow-meter traceable to the National Institute ofStandards Technology (NIST). Standardconditions are 70ºF and 14.7 psia(See photo page 34).
Air flow can be measured for any of thefollowing conditions:
Pressure 0-5, 0-10, 0-20, 0-50, 0-100 psig
Vacuum 0-30" Hg
Flow 0-.002, 0-.01, 0-.02, 0-.05,0-.1, 0-.2, 0-.5, 0-1, 0-2, 0-5,0-10, 0-20, 0-50, 0-200 SLPM

Water FlowCalibration of standard orifices using wa-ter flow is accomplished by measuring thequantity of water flowing through an ori-fice in a given time period at a specific in-let pressure.
The calibration procedure determines thewater flow rate through the orifice and thecorresponding Cv of the orifice is calcu-lated. The Cv can then be used to predictthe water flow rate at varying differentialpressure conditions using the equation:
Q = Cv ∆P
For liquids other than water flow rate canalso be predicted using the Cv method. Seepage 36 for details on liquid flow - Cvmethod.
A calibration sheet with measured data isprovided for each orifice. The calculated Cvis the average value computed from fiveseparate tests (see sample below).
Cv MeasurementWater at a constant height equivalent to 1 psig isused to determine the amount of water that passesthrough a test orifice in a measured time period.The Cv is calculated from the measured data.

Choked Flow of Gases
When the air velocity reaches sonic velocity(P2/P1 ≤ .528) further increases in P1 (upstreampressure) do not cause any further increase inthe air velocity through the orifice. Conse-quently it is wrongly concluded that the massflow rate also does not increase.
As the air pressure (P1) increases, the densityof the air also increases; and since the massflow rate is also a function of density, the massflow rate increases linearly with pressure (P1).
Even though the air velocity through the orifice is limitedto the speed of sound, the mass flow rate continues toincrease as the absolute pressure (P1) increases.
What is Choked?The parameter that becomes “choked” or“limited” is the velocity of the air. It is moreaccurate to use the term “choked velocity”rather than “choked flow” when the absolutepressure ratio of air through an orifice is≤ .528.
Vacuum Conditions
Air at atmospheric pressure enters the orifice and flowsto a downstream vacuum pump.
In the case of vacuum conditions on the outletof an orifice and where the inlet is at ambientatmospheric pressure, both the air velocityand the mass flow rate become choked(limited) when sonic velocity is achievedthrough the orifice.
For atmospheric inlet pressure and downstream vacuum,both the air velocity and mass flow rate are limited.
The Basic ConceptA greatly misunderstood and misappliednotion is that of “choked flow”, also referredto as “critical flow”.
In gas flow through an orifice there is an occa-sion where the gas velocity reaches sonicconditions. This occurs for air flow when theabsolute pressure ratio is .528, i.e. when thedownstream absolute pressure (P2) is 52.8%of the upstream absolute pressure (P1).
Sonic velocity occurs for air flow whenP2
/P1 ≤ .528.
The air flow velocity is limited once the absolutepressure ratio is ≤ .528.
For air flow through an orifice with aninlet air temperature of 68oF the choked(sonic) velocity is 1129 ft/sec.
The Misconception!Once sonic velocity is achieved in orifice airflow (P2/P1 = .528), it is easy to "assume" thatthe mass flow rate is constant for all pressureratios less than .528; i.e. P2/P1 ≤ .528. Forexample, when P2 is 14.7 psia and P1
is 27.84psia, sonic velocity occurs through the orifice.As P
1 further increases there is no further
increase in the velocity of the air flowingthrough the orifice.
Conditions for the onset of sonic velocity in orifice air flow.
Consider all the Factors!The mass flow rate through an orifice is a func-tion of three basic parameters.
Q (flow) is a function of• Velocity• Density• Orifice Area
The reason for the mass flow rate limitation isthe fixed inlet density combined with the fixedvelocity. The flow charts on pages 16-18 showthe choked mass flow effect for vacuum con-ditions. At vacuum levels between 15-30” Hgthe mass flow rate is fixed.
Choked Flow for PositivePressure ConditionsAs in the case of the above vacuum conditionsthere are certain situations in which chokedflow does occur for positive (above atmo-spheric) pressure. By maintaining a fixed in-let pressure to the orifice and allowing theoutlet pressure (back pressure) to vary, thereis a range of outlet pressures over which themass flow rate is fixed.
For example (see chart below).
• With an inlet pressure of 80 psig, the massflow rate is choked (limited) for all outletpressures less than 35.30 psig (includingvacuum conditions).
• The actual flow rate is constant for theoutlet pressure range of 35.30 psig to aslow as a complete vacuum. The flow ratecan be obtained from the charts on pages16-18; e.g. for an orifice of .010" diam-eter and with 80 psig inlet pressure, thechoked flow rate is 8.4 scfh (page 16). Thisflow rate will be constant for all outletpressure conditions between 35.30 psigand full vacuum.

DescriptionThe fixed flow rate orifices contain adeformable opening which decreases insize as the pressure differential in-creases. The design of the unit compen-sates for pressure differential increaseby reducing the area of the orifice re-sulting in constant flow over the differ-ential pressure range 15-150 psig.

GENERAL DESCRIPTION
The air proximity sensor is a non-contact,no-moving-part sensor, capable of detect-ing the presence of an object at ranges up to1/8". In the absence of an object, air flowsfreely from the sensor resulting in a nearzero output signal. The presence of an ob-ject within the sensing range deflects thenormal air flow and results in a positiveoutput signal.
At low supply pressure, flow from thesensor exerts only minute force on the ob-ject being sensed and is consequently ap-propriate for use where the object is light-weight, or easily marred by mechanical sen-sors. Since there are no moving mechanicalparts in the air proximity sensor, there are noinherent wear mechanisms or life limita-tions. In this regard, the sensor is not cycledependent and is particularly appropriatefor applications requiring large numbers ofcycles. Also, the air proximity sensor isinherently explosion-proof and self-purging.Consequently, it is suitable for many ad-verse environments.

Air/Air AmplifierDESCRIPTIONThe air/air amplifier requires only low pressure signals to pilot a directional control valve,which in turn, can operate at supply pressures up to 100 psig. A control signal of 2" H2Opressure is sufficient to shift the 4 way valve and produce an output signal up to 100 psig. Themain valve is of five ported-4 way construction, and can be used additionally as a 3 way valve,either normally closed or normally open.
PROXIMITY SENSOR – INTEGRAL MOUNTINGP/N OKC-424
PROXIMITY SENSORP/N OKC 818 (Formerly 6080517)
When an object is located inside the sensing range, the sensor flow is deflectedwith a resultant pressure buildup in the output. This pressure signal is the "on"condition of the sensor. The amount of pressure sensed increases as the objectmoves closer to the sensor. Nominal maximum sensing range is 1/8 inch.
In the absence of an object disturbing the free flow of air exiting from the sensor,the output pressure signal is in an "off" condition. This "off" condition is a nearzero output pressure.

Air/Electric SwitchesDESCRIPTIONThe air/electric switches presented here operate readily with the airproximity sensor. Each responds to low pressure air signals, and eachhas special characteristics which increase the total range of applica-tions of the air proximity sensor. Considerations in selecting a switchare current requirements, response time, differential or single endedoperations, and maximum required sensing range.
FEATURESP/N OKC-661 Excellent vibration resistance; small size; pressure,
vacuum or differential operation; fast response time.P/N OKC-664 Greatest current capacity (10 amps); pressure only;
SPDT contacts; moderate response time.P/N OKC-819 Smallest size; fastest response time; up to 60 mil-
liamps; pressure, vacuum or differential operation.
NOTES① A separate electrical connector is provided for soldering to the electrical wire
terminals. Soldering must be done with the electrical connectors removedfrom the switch to prevent damage to the switch contacts by soldering heat.
≠ When controlling inductive loads, such as small relays, it is good practice touse RC suppression or diodes, as required to prevent arcing.
➂ Range – Maximum sensing distance for combination of air proximity sensorand air/electric switch.
√ Response Time – Combined response time of air proximity sensor and air/electric switch.

SELF-REGENERATIVE
Low Dew Point Air Dryers 3
DescriptionThe air dryer products of O'Keefe Controls Co. employ a self-regenerative, desiccant style drying system. "Self-regenerative"means that the dryer automatically and continuously dischargescollected water vapor which has been removed from the air passingthrough the system. Desiccant style means that a material(a desiccant) is used to selectively remove water vapor from the airsurrounding this material. Three common desiccant materials aresilica gel, alumina and molecular sieve.
How It Works!In the O'Keefe Controls Co. air dryers desiccant material is amolecular sieve. This type desiccant absorbs the water vapormolecule in tiny pores on the surface of each bead of the molecularsieve material. Moist air passing by this desiccant is dried as vapormolecules are selectively attracted to the pores in the molecularsieve beads. A dew point as low as minus 100°F is possible usingmolecular sieve material.
Another equally important characteristic of the molecular sieve isthat extremely dry air (very low dew point) passing by thisdesiccant will reabsorb the water vapor trapped in the pores; thusproviding a means of automatic regeneration of the desiccant.
Two desiccant tanks are employed in each air dryer. Wet pressur-ized air enters one tank and is dried as it passes through to the outlet.A portion of the dried air is directed into the top of the second tankthrough a purge orifice and flows at near atmospheric pressurethrough this tank to atmosphere. As this dry air passes around themolecular sieve beads it reabsorbs water vapor and then exhauststo atmosphere.
Flow Patterns in Desiccant Air DryerThe flow patterns shown below have a repeating cycle period of 60seconds. For 30 seconds the left tank is pressurized; for 30 secondsthe right tank is pressurized.
Dew Point and Relative HumidityDew Point – Temperature at which condensation begins. Air is fullysaturated with water vapor at this temperature.Atmospheric Dew Point – Dew point when air is at atmosphericpressure.Pressure Dew Point – Dew point when air is at elevated pressureabove atmospheric pressure.Relative Humidity – Ratio of the actual water vapor content to thesaturated water vapor content.See chart below.

Construction of Desiccant TankThe desiccant tank construc-tion is vital to reliable opera-tion of the air dryer. As shownat left the desiccant beads aremaintained in place by filtermedia and screens. The unit isspring loaded to counteract highpressure pulses which occurduring switching of the air flow.

INSERT MODULE
Standard Air Dryer 7
DescriptionThe 311C series air dryer is an insert module intended to be installedwithin an enclosure. The unit is a self-regenerative compressed air dryerwhich removes water vapor continuously using a molecular sievedesiccant material. Two stainless steel tanks contain the desiccant. Atimer, solenoid valve and two flow control valves sequence the air flowalternately through one tank and then the other. A small amount of purgeflow is discharged continuously. A nominal dew point of -50°F isachieved at maximum flow rate; even lower dew point at less thanmaximum flow. Compressed air supplied to the dryer should be clean(5 microns) and oil-free.
SpecificationsInlet Pressure – 80 to 125 psigMaximum Inlet Temperature – +125°FDew Point – See chart for typical conditions – page 9.

DescriptionThe 2016 series air dryer employs a solid state timer. Electric connectionsemploy a DIN 43650 connector which is gasketed and protected againstinadvertent contact. The unit is a self-regenerative compressed air dryerwhich removes water vapor continuously using a molecular sieve desiccantmaterial. Two stainless steel tanks contain the desiccant. A timer, solenoidvalve and two control valves sequence the air flow alternately through onetank and then the other. A small amount of purge flow is dischargedcontinuously. A nominal dew point of -50°F is achieved at maximum flowrate; even lower dew point at less than maximum flow. Compressed airsupplied to the dryer should be clean (5 microns) and oil-free.

Point-of-Use Air Dryer System 17
DescriptionThe "point-of-use" compressed air dryer re-moves liquid water using filters; and reducesthe pressure dew point of the air throughpressure reduction. The system consists of aprefilter and a coalescing filter, followed bya pressure regulator. Two gages and mount-ing hardware are included in the system.Maximum flow rates of 10, 20 and 40 scfmare available as standard.
While depression of dew point with thesystem is not as dramatic as in desiccant airdryers, it is an economical approach to solv-ing local in-plant air line water problems.
How It Works!Assume that the air entering the filters con-tains liquid water and water vapor at 100%relative humidity. The air exiting the filtersis virtually free of liquid water, but is still at100% relative humidity as it enters the pres-sure regulator.
Since pressure regulators reduce pressure,there is a corresponding decrease in thedensity of the air at the exit from the regula-tor. Not only is the density of the air reduced,but also that of the water vapor, resulting ina decrease of the relative humidity. Satu-rated water vapor entering the regulator is nolonger saturated in the reduced pressure atthe outlet.
The dew point chart (at right) illustrates thereduction of dew point that can be achieved.The lower the outlet pressure of the regulatorthe lower is the relative humidity and associ-ated dew point. The assumption for the chartdata is that heat transfer maintains the tem-perature reasonably constant during flowpassage through the pressure regulator.
Where To Use the Air Dryer!Install this dryer close to the "point of use" toinsure that there is no substantial tempera-ture decrease between the regulator anddownstream use point.
It is good practice to maintain the regulatoroutput pressure a minimum of 20 psi belowthe regulator input pressure. The two gagesprovided are for this purpose.

SENSORS
Pneumatic Controls 23
Pneumatic Pressure SwitchThe Pneumatic Pressure Switch combines apressure sensing element and a spool valve toproduce a switching device with an adjustableset point. The assembly is non-electric, usingonly air or inert gas in the switch unit.
The pressure sensor is compatible with air,water, steam, oil and many corrosive liquids or
gases. Setpoint is adjustable – vacuum up to 6000 psig.
Air signals from the 5 ported 4-way valve in the switch unit can beeither vacuum or positive pressure up to 100 psig. RequestBulletin OK-043.
Pneumatic Liquid Level SwitchThe Liquid Level Switch is an air sensor fordetecting liquid level inside a vessel. The floatmechanism mounted within the vessel oper-ates a ceramic coated magnet. A magneticallyactuated sensor on the outside of the solid
metal housing reacts to the inner magnet move-ment. The movement shifts a 3-way air valve.
Both side mounted (shown here) and top mountedunits are available. Wetted materials are brass or stainless steel.
The magnetic sensor unit operates at air pressure from 30 to 100psig. The 3-way valve signals can pilot alarms or control elements.Request Bulletin OK-242.
Pneumatic Flow SwitchThe Pneumatic Flow Switch is an air sensorfor detecting the flow of liquids or gases in
a pipe. A paddle extends into the fluid and deflectsas the stream velocity increases or decreases.Various sized paddles establish the particularfluid stream flow rate at which the external mag-netic sensor is actuated.
The air sensor is a 3-way valve which operates atpressures from 30 to 100 psig. Flow switch units are available from1/2" to 2" NPT. Wetted materials are brass or stainless steel.Request Bulletin OK-268.
Air Jet Proximity SensorThe Air Jet Proximity Sensor is a non-contact
no-moving-part sensor, capable of detect-ing the presence of an object at rangesup to 1/8". In the absence of an object,
air flows freely from the sensor resultingin a near zero output signal. The presence of an object within thesensing range deflects the normal air flow and results in a positiveoutput signal.
Air supply pressure is 0.5 to 10 psig. Output signals are lowpressure and sufficient to actuate air/electric switches or air/airamplifiers. Request Brochure OK-098.
Pneumatic Temperature SwitchThe Pneumatic Temperature Switch combines atemperature sensing element and a spool valve toproduce a switching device with an adjustable setpoint. The assembly is non-electric, using only air orinert gas in the switch unit.
The temperature sensor is available in direct mount(shown here) or with a bulb and capillary. Wettedmaterials are copper or stainless steel.
Air signals from the 5 ported 4-way valve in theswitch unit can be either vacuum or positive pressure up to100 psig. Request Bulletin OK-088.
Pneumatic Liquid Level IndicatorThe Liquid Level Indicator displays the heightof liquid above the tip of an air tube im-mersed in the liquid. A small amount of airbubbles through the liquid of a vented vessel.The back pressure in the sense tube isdisplayed on a gage. This back pressure
corresponds to the height of the liquid above the top of the sense tube.
Ranges of liquid height vary from 0-1 in. to 0-60 ft. RequestBulletin OK-267.
Differential Pressure Flow SwitchThe Differential Pressure Flow Switch uses a cali-brated flow element to provide pressure signals to anadjustable setpoint differential pressure electric
switch. Gases or liquids can be used. Wettedmaterials are aluminum, brass or stainless steel.
Adjustable flow rate setpoints are available forwater flow ranges from 15-50 sccm to4-12 GPM. Request Bulletin OK-269.
Magnetic Proximity SensorThe Magnetic Proximity Sensor detectsthe presence of a magnetic or steel part inits near vicinity. The 3-way normally closedair valve is actuated when in the presenceof a small magnet or steel part. The valvedeactuates when the small magnet or steel
part is removed.
Since magnetic fields penetrate materials such asaluminum or stainless steel, the proximity sensor readily detects aproperly polarized magnetic piston in a cylinder constructed withaluminum or stainless steel barrels. It is often used in place of limitswitches to detect end of stroke position.
The sensor is available with mounting straps for attachment to around cylinder barrel. Request Brochure OK-248.
