Amplified VeryLow Pressure Sensors AMPLIFIED Pressure Sensors Features Applications * Medical Breathing *HVAC General Description (generic product) 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 to measured pressure. e www.allsensors.com all sensors * 0.25 and 0.50 In H2O Pressure Ranges * Ratiometric 4V Output * Temperature Compensated * Calibrated Zero and Span The output of the device is ratiometric to the supply voltage over a supply voltage range of 4.5 to 5.5 volts.
