Product Details
Small size 18mm thin capacitance ceramic pressure sensor 2~400bar
a.Product description
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.

1. Precautions before use
Ceramic capacitive pressure sensors beyond the use conditions
described in this specification, such as harsh working environment
or overpressure, ceramic capacitive pressure sensors are likely to
be damaged, in use, must comply with the relevant specifications
Instructions.
2, welding precautions
Ceramic capacitive pressure sensor is a combination of ceramic and
metal. The thermoplasticity of the ceramic itself is poor,
The response to heat is relatively fast, and the ceramic body is
easy to crack or weld under the condition of acute cooling and
acute heat. Recommended welding bars: When manual welding, the
maximum power of the constant temperature soldering iron is 25W,
the welding temperature is 280 ~ 320℃, and the welding time is 2S.
Welding times less than or equal to 3 times. The square type is
welded to the pin on a 100 degree heating table.
3. Storage method
In order to maintain the solderability of the pins and ensure that
the packaging material is in good condition, the recommended
storage conditions are as follows:
Storage temperature: 5 ~ 40℃; Storage relative humidity: below
70%RH.
Even under ideal storage conditions, the weldability of ceramic
capacitive pressure sensors decreases over time
Therefore, the ceramic capacitive pressure sensor should be used
within six months from the date of shipment.
