Product overview:

This type of piezoresistive pressure sensitive chip is a pressure sensor suitable for household appliances, automotive electronics, meteorological 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.

This pressure sensitive component is the OEM component adopting PCB assembly, convenient for users' installation, using surface-mount or welding way.

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

Including with temperature compensation and without temperature compensation. Pressure on the back way.

Inside the ring can be covered with silica gel, used for waterp-roof and oil-proof, also can burden the back pressure in the form of gage pressure.
