PSIBAR® CVD TYPES
Gauge, Vacuum, and Compound Pressure Models
General Purpose and Wash down Enclosures
High Proof Pressure Achieved by Thicker Diaphragm Construction
Voltage and Current Output Models
The 1200 Series features stability and toughness via its CVD and ASIC design coupled
with a thicker diaphragm. The thicker diaphragm enables these sensors to survive
most pressure spikes caused by pump ripple, solenoid valves, etc. The 1600 Series
extends the packaging options by providing an all welded stainless steel back end
for demanding industrial applications. A modular design allows special ordering of
fittings, electrical cables, etc. for OEM applications. The ASIC and CVD technology
enables Gems to offer almost any output over any pressure range.

Monitor Liquid Level with Gems Psibar
®
Pressure Transducers
Continuously Monitor Liquid Levels
Stainless Steel Wetted Parts are Compatible With Most Fluids
Mount Through Top or Side of Tanks
Digital Panel Meter
Gems Psibar
®
pressure transducers provide a great, cost-effective
method for measuring liquid levels. From measuring inventories in
process storage tanks to monitoring hot water feed tanks, our design
flexibility promotes easy installation, with mounting either through the
tank top or from the side.
Getting Started…
Tank content is be determined from the pressure exerted on the
sensor, so you need to know the depth
and
the specific gravity of
the liquid being measured. When these two factors are known, the
following equation can be used to determine the pressure range
needed to specify an applicable pressure transducer:
Pressure in PSI = Liquid Level (in feet) x (Specific Gravity x 0.433)
Example:
Tank Level:
Pressure in PSI = Liquid Level (in feet) x (Specific Gravity x 0.433)
Pressure in PSI = 30 x (1.0 x 0.433)
Pressure in PSI = 12.99 PSI
Using a Psibar Series 1200, 1600, 2200 or 2600 transducer, specify
Pressure Range code
F15
(0-15 PSI).
