Product Description

Pressure ceramic Capacitve sensor Warm pressure integrated capacitor core car motor oil sensor


Ceramic capacitance pressure sensor material selection of 96% ceramic, has strong corrosion resistance, impact resistance, high elasticity and other excellent characteristics, while the extremely high thermal stability of the ceramic makes its operating temperature range of-40℃ ~135℃ .In the working process of the ceramic capacitance pressure sensor, it does not need to transfer the pressure through other media. The monitoring pressure acts directly on the ceramic diaphragm, and the electric capacity change between the base electrode and the diaphragm electrode is proportional to the pressure.When overload, the diaphragm reaches against the base without breaking. When the pressure recovers, its performance will not be affected, which completely solves the disadvantages of low-range overload failure. It is

        the replacement product of ceramic pressure resistance and diffusion

        silicon pressure sensor.
