ME750
Metallux
ME75x and MEP75x are 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 diaphragm by means of Thick Film
technology and signal conditioning electronics are added to generate 0.5…4.5 V
ratiometric output (ME750), current loop 4…20 mA (ME751) or 0…10 V non
ratiometric output (ME752). Also available in customized version I2C output.
Pressure and temperature calibration are done electronically with the on-board
ASIC and can be performed in bar (ME75x) or in psi (MEP75x). Electronics
provide offset and span correction when temperature changes. Aging detection and
compensation are constantly performed. This new method guarantees good
precision and longterm stability. The Metallux ME75x family meets EMI
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 ME75x sensors are suitable for nearly
all aggressive media.
