Pressure Sensitive Ceramic Capacitor

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°C ~ 150°C. 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 touches the base without damage; when the pressure returns to normal, its performance will not be affected, which completely eliminates the shortcomings of poor low-range overload capacity, and can be used to upgrade and replace the diffusion silicon pressure sensor.
