Industrial Pressure Gauges:

Standard Range:

H.Guru South 'Industrial Pressure Gauges' are suitable for all general industrial applications. They are robust in their construction and are ideal for field applications. These gauges come with bourdon tube sensing elements. They have guaranteed initial accuracy and repeatability. The accuracy is maintained longer, a result of a sound design and fabrication of all the critical components, in house. The design incorporates a blow out disc in order to maintain safety. These gauges are available with material and calibration certificates. Performance is as per IS 3624-1987. They are available in a variety of casing options to suite most environments and applications.

** This red pointer (shown here in grey) shows the maximum value attained since the pointer was last reset. They are engaged by a small pin on this pointer. If this pointer is omitted, this pointer becomes an index pointer, which acts as a guide to the plant attendant. This pointer assembly is mounted on an acrylic plastic window adjustable from front, by using a screw driver through an adjustable screw.

These gauges are typically used in very harsh and highly corrosive environments. They are used in chemical, fertilizer and petrochemical industries due to their tolerance to the corrosive environments that such industries offer.

Solid Front Industrial Pressure Gauge:

Solid Front Pressure Gauges are high safety gauges used in process industryapplications. These essentially have a shield behind the window of the gauge to prevent any shock created within the gauge from shattering the window. These gauges also incorporate a safety back with blow out discs to vent the pressure through the back, in the event of an internal failure. These gauges are ideally suited for applications where the risk of explosion of the pressure system is existent.

Additional Technical Specifications:Dial Sizes: 150mmAccuracy (10~90% of scale): +/- 1% FSDCasing Options: Cast Aluminum LM6 Alloy, SS (Refer Table PGI-3 for details) *All Other Specifications as in Standard Range.

Optional Extras: Drag Pointer** Cleaning for Oxygen, Acetylene, or other special services. Special Ranges & Scales : PSI, MPa, KPa etc. Custom made Dials with special markings. Applicable Accessories

*Computer Code Construction as in Standard Range.

Liquid Filled Pressure Gauges:

Liquid filled gauges are used in applications which involve high mechanical vibration and pulsating pressure. The sensing element, movement and pointer are kept immersed in a liquid which dampens their motion and lengthens their life. These instruments are designed for use on power units, pumps, hydro cleaning machines, compressors, turbines, diesel engines, chemical lines and refrigerating plants and machines and equipment. *Caution: To avoid possibility of explosion, gauges with glycerine filling should not be used to measure O , Cl, HNO , H O , NH and other strong oxidizing 2 3 2 2 3

agents. The use of fluronate fluid filling is recommended for such applications.

This corrosion chart has been prepared to assist you in the selection of materials that is suitable to your application.It is essential that the wetted parts of the instruments be compatible with the process fluid. To use the chart below,locate the fluid whose pressure is to be measured and select a material, from the compatible materials, which are indicated by a dot. The below data has been extracted from various sources and the general assumption is that the

Oprocess fluid is at a temperature below 80 C except where specified. However, final selection of material is recommended to be made only after verifying the same with qualified personnel.
