Principle and application of ceramic pressure sensor

Corrosion-resistant ceramic pressure sensor is not the transmission fluid pressure directly on the front surface of the ceramic diaphragm , the diaphragm will produce a slight deformation , thick film resistors printed on the back of the ceramic diaphragm , connected into a Wheatstone bridge (closed bridge ) , the piezoresistive effect varistor , so that the bridge is proportional to the pressure to generate a highly linear , the excitation voltage is proportional to the voltage signal , the standard signal calibration according to different pressure range of 2.0 / 3.0 / 3.3 mV / V , etc., can be compatible and strain sensors . By laser calibration, Coolant Temp Sensor  has high temperature stability and time stability , the sensor comes with temperature compensation 0 ~ 70 ℃, and the vast majority of the media can be in direct contact .
Ceramic is a recognized high elasticity, resistance to corrosion, abrasion , impact and vibration of the material. Characteristics and thermal stability of the ceramic thick film resistor can make its working temperature range up to -40 ~ 135 ℃, and a measurement of high precision and high stability. Electrical insulation level > 2kV, the output signal is strong , long-term stability . High characteristics, low price ceramic Position Sensor  will be the development direction of the pressure sensor in the United States and Europe have a comprehensive alternative to other types of sensors trend in China , more and more users to use ceramic sensor replacement diffused silicon pressure sensor.
