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

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

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

Important features of the new HRO series:

- Pressure ranges from 10 mbar to 10 bar (4 inH2O to 150 psi)
- Analogue output signals with nearly unlimited resolution
- Special housing design offers ideal protection against stress
- SIL housing with mounting holes and tubing connections

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