Gems Sensors & Controls 1200 Series, 1600 Series Catalog Page

PRESSURE TRANSDUCERS

1200 Series / 1600 Series –
OEM Transducers Featuring Exceptional
Proof Pressure and Stability Specifications

 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.

Psibar

transducers incorporate components to
leverage the sensing element’s strength. The output is
a product with a unique balance of performance and
value unmatched in today’s pressure sensing market.

Thicker diaphragm for handling
pulsating pressures –
all stainless steel wetted parts.

CVD sensor stability and high
sensitivity allows use of our
thicker diaphragm. 17-4 PH SS
sensor beam is laser welded for
distortion-free construction.

Weldless
stainless steel
case.

ASIC chip is the brains
behind the brawn.
Programmability provides
greater linearity correction
than common thermal
compensation methods.

RFI/EMI & ESD protection circuit
meets and exceeds requirements for
CE marking. Protecting against noise,
voltage spikes and static discharge.
