Miniature Low Pressure Sensors * * * * 0 to 2" H2O to 0 to 30" H2O Pressure Ranges Matched pressure port volumes Temperature Compensated Calibrated Zero and Span Applications all * Medical Instrumentation * Environmental Controls * HVAC sensors Features General Description The Millivolt Output pressure sensors is based upon a proprietary technology to reduce all output offset or common mode errors. 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 e www.allsensors.com Low Pressure (2" H2O to 30 " H2O) Sensors 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 f 408 225 2079 sensitivity are all significantly reduced when compared to conventional compensation methods. In addition the 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.
