Metallux ME670 monolithic pressure sensor are made with ceramic cell and work following the piezoresistive principle.

Metallux ME670 sensors are developed for optimal electronic integratio: the offset is adjustable following customers’ specification and the sensors are also available thermally compensated by laser-adjustable PTC resistors. Pins layout on two lines is optimized to allow easy and steady mounting of signal conditioning PCB. The Wheatstone bridge is screen printed directly on one side of the ceramic diaphragm by means of Thick Film technology. The diaphragm’s opposite side can be exposed directly to the medium to be measured. Because of the Al2O3 ceramic excellent chemical resistance, no additional protection is normally required. Thanks to the reinforced outer area (monolithic structure), the sensor allow easy integration directly in a plastic or metallic case by using O-ring.

ME670 sensors are designed in such a way so that temperature changes and pressure overloads do not cause loss in reliability. Use of ceramic ensures high linearity across the entire range of measurement and minimizes effects of hysteresis.
