Pressure sensitive element: pressure sensitive element, which can sensitively feel and respond to the measured pressure variable. It has good sealing and will produce a rapid linear response to the change of external pressure. It is widely used in the aviation field to achieve the corresponding extension or contraction through the pressure difference between the ground and the air to achieve the automatic opening and closing effect of the pipeline valve, such as deflation movable components, vacuum diagram switches, etc.

· High sensitivity and high precision up to 0.05%, including nonlinearity, hysteresis and repeatability
· high reliability and stability
· Small volume, light weight, metal integrated structure
· wide temperature range (- 200 ℃ ~ 650 ℃)
