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 methods. 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 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.
