1200 Series / 1600 Series- PSIBAR an OEM Transducer 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 Psibar features stability and toughness via its CVD and ASIC design coupled with a thicker diaphragm. The thicker diaphragm enables psibar 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. The psibar’s modular design enables 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.
