Metallux ME663 monolithic pressure sensors are made with a 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. Metallux ME663 sensors can be thermally compensated by laseradjustable PTC resistors and differ from the Metallux ME651 family because of the connection pads reduced pitch. The diaphragm’s opposite side can be exposed directly to the medium to be measured. Because of the Al2O3 ceramic excellent chemical resistance (aggressive gases, most of solvents and acids, etc.), no additional protection is normally required. Thanks to the reinforced outer area (monolithic structure), the sensor can be mounted in a plastic or metallic case by using O-ring. ME663 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.
