Product overview:

Piezoresistive pressure sensor is a type of pressure sensor which is suitable for household appliances, automotive electronics, industrial areas, etc., its core is a silicon piezoresistive pressure sensitive chip using MEMS technology processing. This pressure sensitive chip is composed of a elastic membrane and four resistors integrated on the film, four varistors forming the structure of wheatstone bridge, bridge produces a voltage output signal which has a linear proportional relationship with the added pressure when there is pressure effect on the elastic membrane. 

Pressure sensitive element: using TO - 5 metal shell encapsulation OEM components, convenient for users' circuit board installation and good sealing.

Good linearity, repeatability and stability, high sensitivity, convenient for users' deb ing for output applying op-amp or integrated circuit.

Including with temperature compensation and without temperature compensation.

Inside the ring can be covered with silica gel, used for protection; water-proof and oil-proof, can use wate-rproof and oil-proof silicone.
