1-30 +vsupply 3 + voutput 2 -vsupply 1 -voutput 4 the millivolt output pressure sensors is based upon a proprietary technology to reduce all output offset or common mode errors. this model provides a calibrated millivolt output with superior output offset characteris- tics. 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. these calibrated and temperature compensated sensors give an accurate and stable output over a wide tempera- ture 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 and operation from any d.c. supply voltage up to +16 v is acceptable. low pressure (2? h 2 o to 30 ? h 2 o) sensors ? 0 to 2? h 2 o to 0 to 30? h 2 o pressure ranges ? matched pressure port volumes ? temperature compensated ? calibrated zero and span ? medical instrumentation ? environmental controls ? hvac general description applications features miniature low pressure sensors equivalent circuit input resittance output resistance 15 k ohm 1.5 k ohm
