Product Description

 

Product Description

CYX2210 series differential pressure sensor is a differential pressure sensitive device isolated by stainless steel double corrugated diaphragm. The accurate measurement is achieved by transmitting through the isolation diaphragm and filled silicone oil to the silicon pressure-sensitive element. The core adopts piezoresistive chip with international advanced silicon pressure chips with high stability and high precision, and adopts the sintering base with stress optimization design. The sensor is produced by the following processes: patching, gold wire bonding, diaphragm welding, high vacuum oil injection, pressure cycle stress relief, high temperature aging, temperature compensation, etc. The shape, size and sealing mode of the general products are consistent with the international mainstream products of the same kind, and have good interchangeability. They are widely used for differential pressure and liquid level measurement of compatible media with 316L stainless steel, NBR or FKM.

7 Application Tips

1. The leading line end of the sensor is a high-pressure end, and the other end is a low pressure end. The "H" and "L" marks on the sensor can also be used to identify the high- and low-pressure ends. During operation, the pressure added to the high-pressure end should not be less than the pressure added to the low-pressure end.
2. Housing: the inlet end of assembly cavity should be designed with a conical angle, which is easy to assemble and prevent the right angle from scratching the sealing ring. The "floating" sealing structure of O-ring on the side wall is recommended for sealing the differential pressure sensor, which can avoid the front end being compressed and the stability being affected.
3. Pay attention to protect the front and rear diaphragm and middle compensation circuit board, so as not to affect the performance or cause damage to the pressure sensor.
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. Avoid falling, crashing, etc., which will affect the stability of the product.
6. In case of any change of pin lead, the label with the pressure sensor shall prevail.
