Description

Metallux ME771 pressure sensors are made with a ceramic base body glued to flush diaphragm and work following the piezoresistive principle. The Wheatstone bridge is screen printed on one side of the ceramic diaphragm. The bridge faces the inside of the sensors where a cavity is made. Signal conditioning electronics are added to generate current loop 4...20 mA output).

Pressure and temperature calibration are done electronically with the on-board ASIC and can be performed in bar (ME771) or in psi (MEP771). Electronics provide offset and span correction when temperature changes. Aging detection is constantly performed. This new method guarantees good precision and long-term stability.

The Metallux ME771 family meets EMC requirements. The ASIC stores production lot specific data for sensor traceability and allows custom calibration. Due to the excellent chemical immunity of the the Al2O3 ceramic, the ME771 sensors are suitable for nearly all aggressive media.
