Gems Sensors Pressure Transducer
OEM Pressure Transducer Featuring Exceptional Proof Pressure and Stability Specifications- Vacuum to 6000 PSI (400 Bar)
Quick Specs...
- Voltage and Current Output Models
- Gauge, Vacuum, and Compound Pressure Models
- General Purpose and Wash Down Enclosures
- High Proof Pressure Achieved by Thicker Diaphragm Construction
Overview / Design Principle:
The 1200 series pressure transducer 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. 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.
Applications:
- Off Highway Vehicles
- Natural Gas Equipment
- Semiconductor Processing
- Power Plants
- Refrigeration
- Robotics
- HVAC
