Product Details

LCP Ceramic Piezoresistive Pressure Sensor is assembled based on ceramic. The measuring bridge is printed directly on one side of the ceramic diaphragm by means of thick film technology. The rear part of the diaphragm can be exposed directly to the medium to be measured. Normally, additional protection is not required because of the excellent chemical resistance. With reinforced outer area (monolithic structure), the sensor can be mounted directly into a case or a metal fitting by an O-ring or else. In such design, temperature changes and overloading can not cause any loss in reliability. The use of ceramic ensures high linearity across the entire range of measurement and reduces effects of hysteresis to a minimum.Additionally, LCP Ceramic Piezoresistive Pressure Sensor is thermal compensated by PTC resistors. The offset can be adjusted on customer specification.
