Product Description

Product Description

  CYX 32 series oil injection core pressure sensor adopts the internationally advanced high stability and high precision silicon pressure chip, and adopts the sintering seat with stress optimization design, which is produced by the processes of chip mounting, gold wire bonding, diaphragm welding, high vacuum oil injection, pressure cycle stress relief, high temperature aging, temperature compensation, etc. With more than 30 years of development, production experience and technological innovation, the products have excellent stability and performance, and are widely recognized by users.

1.1General CYX32 pressure sensor
The shape, assembly size and sealing method of the general CYX32 are consistent with the same kind of international mainstream products, which gives CYX32 good interchangeability. It is widely used in the pressure detection of the medium compatible with SS316L, NBR.

1.2CYX32 pressure sensor with chloride ion corrosion resistance
CYX32 pressure sensor shares the same shape, assembly dimension and sealing form as the general CYX32. Structure uses titanium alloy: TC4 with high strength and good corrosion resistance is selected as the shell, TA1 is selected as the diaphragm, which is more suitable for the medium with strong corrosion of chloride ions such as seawater. Working in humid atmosphere and sea water medium, its corrosion resistance is far superior to that of stainless steel products. It has strong resistance to pitting, acid and stress corrosion, and excellent corrosion resistance to organic substances of alkali / chloride /chlorine, nitric acid, sulfuric acid, etc. Measurement range is -100kPa ~ 0 ~ 10kPa…100MPa.

7 Application Tips

1. The "floating" sealing structure of O-ring on the side wall is recommended for sealing the pressure sensor, which can avoid the front end being compressed and the stability being affected.
2. Pay attention to protect the front diaphragm and the compensation circuit board at the rear end, so as not to affect the performance or cause damage to the pressure sensor.
3. The shell cavity shall be designed with tapered angle as shown in the figure, which is easy for assembly and can prevent the seal ring from being scratched by right angle. 
4. During assembly, pay attention to the tolerance fit between the pressure sensor size and the inner shell of the transmitter. It is recommended that the cavity be processed according to + 0.02 - + 0.05 of the pressure sensor diameter to achieve the required air tightness.
5. During assembly, it is required to place vertically and press down evenly to prevent the shell from jamming or damaging the compensation plate.
6. Do not press the metal diaphragm with hands or hard objects to avoid damaging the pressure sensor due to chip deformation or perforation.
7. When wiring, the pins should not be cut too short, the length is generally no less than 5mm, and the welding time is no more than 5s.
8. The pressure lead-in tube at the back of G type pressure sensor shall be connected with the atmosphere; water, steam or corrosive medium shall not enter the reference cavity at the back of the sensor body.
9. Avoid falling, crashing, etc., which will affect the stability of the product.
10. In case of any change of pin lead, the label with the pressure sensor shall prevail.
