Ceramic Capacitive Pressure Sensor

Ceramic capacitive pressure sensor features corrosion resistance, impact resistance and high elasticity, which can directly contact with most of the medium. In addition, the high thermal stability of ceramic makes its Operation temperature range can reach -40℃~150℃, so it can be widely used in automotive and industrial process control and other fields. There is no liquid transfer in the working process of ceramic capacitive pressure sensor, the process pressure directly acts on the ceramic diaphragm, and the capacitance change between the base electrode and the diaphragm electrode is proportional to the pressure. When overloaded, the diaphragm will touch the base without damage, which can effectively replace the diffused silicon pressure sensor and completely solve the problem of poor overload capacity at low range.
