Common Problems Solved with

Sentry Sampling Systems

Problem #1: Non-constant Flow to Analyzers

Sentry VREL and BPR/RV in Tandem VREL Reduces Bulk of Pressure BPR/RV Does Fine Pressure Control Shock Absorber- Extra Flow through

BPR/RV Flat Flow vs. Pressure Curve

Problem #2: Poor Sample Temperature Control

Competitor’s Bath Systems are not “Isothermal” Competitor’s Bath Systems typically only cool Bath has Poor Approach Temperature due to Low

Turbulence Sentry System uses Dedicated Secondary Coolers High Surface Area- Close Approach Temperature +/- 0.25 C control with Chiller; 25+/- 0.5 C through

Sentry Coolers

Problem #3: Plugging Sample Lines

Typically caused by Oversized Sample Lines

Also Caused by Low Flow Sentry Properly Sizes Coolers with Cooler

Program Sentry Recommends Low Pressure

Blowdown

Problem #4: Samples Too Hot

Many Times Competitor’s Coolers are Undersized

Computer Sizing Can Eliminate Sentry has over 30 Cooler Models,

Competitors have 2 to 4 models Sentry models include 0.11, 0.16, 0.22,

0.33, & 0.44 Square Meter Surface Area

Problem #5: Rusting/Patched Panel Front

Most Competitor’s Panels have Painted Carbon Steel Fronts

Sentry Panel has Corrosion Resistant Modular 304 SS Front

Modular Front Allows Future Changes Without Patching the Panel Front

Problem #6: Too Low Sample Flow

Competitor’s Don’t Size Coolers Properly Steam Samples, Especially Low Pressure

Steam, Needs High Capacity Sample Cooler Sentry has Special High Surface Area/Low

Pressure Drop Coolers- FLF-6222/FXF-6223

Problem #7: Thermal Excursions Thermal excursions can cause operator injury,

damage cells, analyzers and other components and discharge of steam to atmosphere

Thermal excursions can be caused by loss of cooling water, high sample flow rate, fouled or plugged sample cooler or high cooling water temperature

Thermal Shut Off Valves - requires no pneumatic or electrical power, re-settable latching design, positive position indication, compact package

Optional switch for remote indication

Problem #8: Multiple Independent Analyzers

Calibration differences can occur between independent analyzers

Calibration requires valuable time Sharing one analyzer reduces calibration

differences, calibration time, consumable usage, capital cost

Sentry Sequencer is a proven method of analyzer sharing
