Automotive air conditioning system 1Mpa 10bar Ceramic Capacitance Pressure Sensor 18mm 20mm,21mm
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. Notes before use
Ceramic capacitance pressure sensors may be damaged beyond the service conditions described in this specification, such as harsh working environment or overpressure, and must follow the instructions of this specification when used.
2. Welding precautions
Ceramic capacitance pressure sensor is a combination of ceramic and metal.The thermoplasticity of the ceramic body itself is poor, and the response to the heat is relatively fast. Under the condition of urgent cold and urgent heat, the ceramic body is easy to crack or virtual welding.Recommended welding conditions: when manual welding, the maximum power of constant temperature dering iron is 25W, welding temperature 280~320℃, welding time 3S, welding times less than or equal to 3 times.The ons shall be welded on a 120 degree heating table.
3. Storage method
To maintain the weltability of the pins and ensure the packaging material in good condition, the recommended storage conditions are as follows: storage temperature: 5~40℃; storage relative humidity: below 70%RH. Ceramic capacitance pressure sensor soldability decreases over time, even under ideal storage conditions, and therefore should be used within half a year from the date of delivery.
