Small Size 18mm Thin Capacitance Ceramic Pressure Sensor 2 - 400bar for Refrigerator

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.

C. Applications :

Automotive oil sensor Automotive braking system

Automotive air conditioning system

New energy vehicle thermal management system

Automotive intake and exhaust system

Screw air compressor,

Variable frequency water pump system (water will affect the core capacity value,The core pressure surface to do special treatment)

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.
