Pressure ratio welded bellows of pressure sensing element
The pressure ratio welded bellows type uses the different pressure sensing areas of the inner and outer diaphragm box to output axial force or axial displacement. By designing different inner and outer diaphragm box sizes and middle chamber pressure, the accurate control of pressure and displacement in various occasions can be realized
Advantage of pressure sensing element：
High sensitivity and high accuracy 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 ℃)
