Miniature Pressure Sensors H-Grade Pressure Sensors Features 0 to 4 H2O to 0 to 100 PSI Pressure Ranges 0.5 % linearity...high accuracy version Temperature Compensated Calibrated Zero and Span Applications Medical Instrumentation Environmental Controls HVAC 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.
