vehicle A/C pressure sensor sensetive aire pressure range of
1~40bars
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.
