General Description
The Miniature series pressure sensors are based upon a proprietary technology to reduce the size of the sensor and
yet maintain a high level of performance. This model provides a calibrated millivolt output with superior output
offset characteristics. Output offset errors due to change in temperature, stability to warm-up, stability to long time
period, and position sensitivity are all significantly reduced when compared to conventional compensation meth-
ods. 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 temperature
range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the
like. The H-GRADE is a high accuracy 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.
