The Millivolt Output pressure sensors is based upon a proprietary packaging technology to reduce output offset
or common mode errors. This model provides a calibrated millivolt output with good output offset characteris-
tics. In addition the sensor utilizes a silicon, micromachined, stress concentration enhanced structure to
provide a very linear output to measured pressure.
These calibrated and temperature compensated sensors give an accurate and stable output over a wide tempera-
ture range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and
the like. The C-GRADE is a lowest cost version of the millivolt output pressure sensors.
The output of the device is ratiometric to the supply voltage and operation from any D.C. supply voltage up to
+16 V is acceptable.
