| Millivolt Output Medium Pressure Sensors C-Grade Pressure Sensors Features * * * * 0 to 0.3 PSI to 0 to 100 PSI Pressure Ranges 1 % linearity version Temperature Compensated Calibrated Zero and Span Applications * Medical Instrumentation * Environmental Controls * HVAC General Description 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 characteristics. 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 up to +16 V is acceptable.
