Ceramic is a recognized material that is highly elastic, resistant to corrosion, abrasion, shock and vibration.
Ceramic is a recognized material that is highly elastic, resistant to corrosion, abrasion, shock and vibration. It has a high stability. In Europe and the United States, ceramic pressure sensors have a tendency to completely replace other types of sensors. In China, more and more users are using ceramic sensors instead of diffused silicon pressure sensors. The principle of ceramic pressure sensors is described below.
The ceramic pressure sensor has no liquid transfer, the pressure acts directly on the front surface of the ceramic diaphragm, causing a slight deformation of the diaphragm, and the thick film resistor is printed on the back of the ceramic diaphragm to form a Wheatstone bridge (closed bridge).
Due to the piezoresistive effect of the varistor, the bridge produces a highly linear voltage signal proportional to the pressure, which is proportional to the excitation voltage. The standard signal is calibrated to 2.0 / 3.0 / 3.3 mV/V depending on the pressure range. Etc., it can be compatible with strain gauge sensors.
With laser calibration, the sensor has high temperature stability and time stability. The sensor comes with temperature compensation of 0 to 70 ° C and can be in direct contact with most media.
The thermal stability of ceramics and its thick film resistance allow it to operate over a temperature range of -40 to 135 °C with high precision and high stability. The degree of electrical insulation is >2kV, the output signal is strong, and the long-term stability is good. High-performance, low-priced ceramic sensors will be the development direction of pressure sensors.
