PMS3051DP/HP Differential pressure gauge

The working principle of metal capacitance differential pressure gauge is that when the pressure acts indirectly on the surface of metal measuring diaphragm (elastic measuring element) of different thickness through isolating diaphragm and conductive medium, the diaphragm produces small deformation, the maximum shape variable does not exceed 0.1mm, and the high precision measuring circuit converts this small deformation into a voltage signal which is linearly related to the differential pressure signal, which is linearized. Temperature compensation, and then use a special chip to convert the voltage signal into an industrial standard 4-20mA current signal or 1-5V voltage signal.
