ME790 and MEP790 are monolithic piezoresistive ceramic pressure sensors. The Wheatstone bridge is screen printed directly on one side of the ceramic cell by means of thick film technology and signal conditioning electronics generate 0.5 - 4.5V ratiometric output. Pressure and temperature calibration are done electronically with the on-board ASIC and can be performed in bar (ME790) or in psi (MEP790).
Electronics provide offset and span correction when the temperature changes. Aging detection is constantly performed. This new method guarantees good precision and long-term stability. The ASIC stores production lot specific data for sensor traceability and allows custom calibration. Excellent chemical immunity of the AI2O3 ceramic, the ME790 sensors are suitable for nearly all aggressive media.
