HRO Piezoresistive silicon pressure sensors

Piezoresistive silicon pressure sensors in a robust housing with ranges up to 10 bar (150 psi)

First Sensor presents the new HRO pressure sensors forgage and differential pressure measurement in a wide range from 10 mbar up to10 bar (4 inH2O to 150 psi) full scale. The robust HRO pressuresensors are calibrated and temperature compensated and can be used with dry andnon-corrosive gases. The completely analogue signal conditioning ensures mVoutput signals with nearly unlimited resolution.

The special HRO housing design offers ideal protection against possiblestress during sensor mounting. The outer package is mechanically decoupled fromthe inner part holding the highly stable silicon sensing element. The HROsensors provide a miniature SIL housing with mounting holes for convenient,space-saving PCB-mounting. Two pressure ports allow for easy tubingconnections.

Important features of the new HRO series:
  • Pressure ranges from 10 mbar to 10 bar (4 inH2Oto 150 psi)
  • Analogue output signals with nearly unlimitedresolution
  • Special housing design offers ideal protectionagainst stress
  • SIL housing with mounting holes and tubingconnections

Typicalapplications of the HRO pressure sensors include industrial,pneumatic and environmental controls, instrumentation, medical devices as well as HVAC.
