Metallux ME790 is a ceramic alumina monolithic pressure sensor working 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 SMD directly on the sensor. Pressure and temperature calibration are done electronically with the SMD ASIC and can be performed in bar (ME790) or in psi (MEP790). Electronics provide offset and span correction when temperature changes. Aging detection and compensation are constantly performed. This new method guarantees good precision and long-term stability. The Metallux ME790 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 ME790 sensors are suitable for nearly all aggressive media.
