Surface Mount Basic Pressure Sensors Applications * Medical Instrumentation * Environmental Controls * HVAC all * 0-100 psi Pressure Ranges * 0.5 % linearity sensors Features The BASIC Serices of pressure sensors use a silicon micromachined (MEMS) pressure sensor in the most basic configuration. The package is a ceramic surface mount configuration to provide the smallest footprint possible. Best temperature compensation is realized when the sensor has a constant current excitation. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. e www.allsensors.com General Description Specifications are written for constant voltage of 3.0 volts. f 408 225 2079 The output of the device is ratiometric to the supply voltage..
