ME790
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.
