Miniature Amplified Pressure Sensors 0.3 psi to 100 psi Pressure Sensors Features 0 to 0.3 to 0 to 30 psi Pressure Ranges Ratiometric 4V Output Temperature Compensated Calibrated Zero and Span Applications Medical Instrumentation Environmental Instrumentation HVAC Instrumentation General Description The Miniature Amplified line of pressure sensors is based upon technology developed over years of development in the pressure sensor industry. This model provides a ratiometric 4-volt output with superior output characteristics. The sensor housing has been designed specifically to reduce package induced parasitic stress and strain. In addition the sensor utilizes a silicon, micromachined, stress concentra- tion 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. Each sensor is internally compensated using an ASIC compensation technique. 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.
