Modell | CYX20 |
Introduction | CYX20 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. |
