Product overview:

This type of piezoresistive pressure sensitive chip is a pressure sensor suitable for household appliances, automotive electronics, industrial fields,  its core is a silicon piezoresistive pressure sensitive chip adopting MEMS technology processing. The pressure sensitive chip is composed of one elastic membrane and four resistors integrated on the film, four varistors form the structure of wheatstone bridge, bridge produces a voltage output signal which has a linear proportional relationship with the added pressure when pressure effects on the elastic membrane.

GZP**1 type pressure sensitive element for the use of the TO - 5 metal shell encapsulation OEM components, convenient user for circuit board installation and good sealing.

Good linearity, repeatability and stability, high sensitivity, convenient user using op-amp or integrated circuit for output for debugging.

Including with temperature compensation and without temperature compensation. 

Can be covered with silica gel inside pipe cap, used for waterproof and and oil-proof, also can burden the front and the back pressure in the form of differential pressure.
