Amplified Low Pressure Sensors 1 mbar (0.4 In H2O) to 30 In H2O Pressure Sensors Military Temperature Grade Features all sensors * 0 to 1 mbar to 0 to 30 In H2O Pressure Ranges * Ratiometric 4V Output * Temperature Compensated (-40C to 125C) * Calibrated Zero and Span Applications * Medical Instrumentation * Environmental Controls * HVAC The Amplified line of low pressure sensors is based upon a proprietary technology to reduce all output offset or common mode errors. This model provides a ratiometric 4-volt 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 e www.allsensors.com General Description temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. The output of the device is ratiometric to the supply voltage over a supply voltage range of 4.5 to 5.5 volts.
