Working Principle of the ar 420-2 Ceramic Pressure Sensor
The ar 420-2 ceramic pressure sensor operates on the principle of piezoresistive effect. When pressure is applied to the sensor’s ceramic diaphragm, it deforms slightly. This deformation causes a change in resistance of the thick-film resistors printed on the back of the diaphragm, which is connected in a Wheatstone bridge configuration. As a result, the bridge generates a voltage signal that is directly proportional to the applied pressure and the excitation voltage. The sensor’s high temperature and time stability are achieved through laser calibration.
