Description
Metallux ME790 monolithic pressure sensors made with ceramic cell and work following the piezoresistive principle. The Wheatstone bridge is screen printed directly on one side of the ceramic cell by means of Thick Film technology and signal conditioning electronics generates 0.5...4.5 V ratiometric output. Pressure and temperature calibration is done electronically with the onboard ASIC and it can be performed in bar (ME790) or in psi (MEP790).
Electronics provides offset and span correction when the temperature changes. Zero correction software to compensate offset shift due to final customer assembly available on request. This allows good precision and long-term stability.
The Metallux ME790 family meets EMC requirements. The ASIC EEPROM stores production lot specific data for sensor traceability and it allows custom calibration. Due to the excellent chemical resistance of the Al2O3 ceramic, the ME790 sensors are suitable for nearly all aggressive media.
