GENERAL PURPOSE/OEM

DESCRIPTION

For applications in hazardous areas that need intrinsically
safe pressure sensors with consistent high levels of
performance, reliability and stability. The 31CS/32CS Series
sputtered thin lm units oer an unbeatable price-to­performance ratio in a small package size. They feature all
stainless steel wetted parts, a broad selection of electrical
and pressure connections, and a wide choice of electrical
outputs ready for installation.

For heavy duty applications, the 32CS Series feature a thicker
diaphragm and a pressure resistor to withstand the rigors
of cavitation or extreme pressure spikes, delivering years or
reliable and stable performance in pulsating applications.
For ATEX & IECEx intrinsically safe pressure transducers,
refer to Setra’s 31IS/32IS.

PRINCIPLE OF OPERATION

Sputtered Thin Film Strain Gauge Pressure Sensors
Using the well proven Wheatstone Bridge principle,
molecular layers are sputtered onto a 17-4 PH stainless steel
diaphragm and the circuit is etched to provide excellent
resistor denition and uniformity. Sputtered thin lm
technology allows the design of simple, highly accurate
and compact strain gauges deposited onto the back of
the sensing diaphragm, which is in direct contact with the
media. This method virtually eliminates drift, while oering
enhanced sensitivity.

Low Cost for High Volume OEM Installations
Thin Film Tech. Assures Long-Term Stability
No Oil Fill Prevents Thermal Instability &

Leakage
Pressure Ranges from 75 PSI up to 32,000 PSI

CE, RoHS Compliant

APPLICATIONS

Industrial Processes
Chemical
HVAC/R Equipment
Water Management
Intrinsically Safe Control Panels
Other Hazardous Areas

PRESSURE CAPABILITY

Application pressure should be
restricted to the rated-range of
the transducer. The maximum
overpressure is the pressure limit
at which the transducer will not
show signicant oset shift. The
minimum burst pressure is the
test-rating for uid containment.

The data in the tables is “times
rate ranges” (xRR).
