Description
Applications
Medical Instrumentation
Environmental Controls
The Miniature Series Pressure Sensors Are Based Upon A Proprietary Technology To Reduce The Size Of
The Sensor And Yet Maintain A High Level Of Performance. This Model Provides A Calibrated Millivolt
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.
These Calibrated And Temperature Compensated Sensors Give An Accurate And Stable Output Over A Wide
Temperature Range. This Series Is Intended For Use With Non-corrosive, Non-ionic Working Fluids Such
As Air, Dry Gases And The Like. The H-grade Is A High Accuracy Version Of The Millivolt Output
pressure sensors.
The Output Of The Device Is Ratiometric To The Supply Voltage And Operation From Any D.c. Supply
voltage.
