Amplified Low Pressure Sensors 1 mbar (0.4 In H2O) to 60 In H2O Pressure Sensors Features * 0 to 1 mbar to 0 to 60 In H2O Pressure Ranges * Ratiometric 4V Output * Temperature Compensated * Calibrated Zero and Span * Medical Instrumentation * Environmental Controls * HVAC General Description The Amplified line of low pressure sensors are 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 all sensors Applications 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 f 408 225 2079 is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. p 408 225 4314 The output of the device is ratiometric to the supply voltage over a supply voltage range of 4.5 to 5.5 volts.
