Flush mount, 0,5 - 4,5 V Ratiometric output, pressure transducer Metallux ME780 flush mount piezoresistive pressure sensors for gauge, absolute or sealed gauge pressure measurement. High reliability. Integrated SMD signal conditioning 0,5 - 4,5 V Ratiometric calibrated and compensated pressure transducers. Metallux ME780 pressure sensors are made with a ceramic base plate and a flush diaphragm and they work following the piezoresistive principle. The Wheatstone bridge is screen printed on one side of the flush ceramic diaphragm, which is in turn glued to the sensor’s body. The bridge faces the inside where a cavity is made. Signal conditioning electronics is directly integrated on the ceramic to generate 0.5...4.5 V ratiometric output. Calibration is done electronically with the onboard ASIC and it can be performed in bar (ME780) or in psi (MEP780). 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 ME782 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 ME780 sensors are suitable for nearly all aggressive media. Metallux ME780 are patented sensors.
