PSIBAR® CVD TYPES

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.

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

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

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.

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