PMD3051GP/GA Rosemount pressure transmitter

The rosemount pressure transmitter working principle of metal capacitive pressure (gauge) / absolute pressure transmitter is that when the pressure acts indirectly on the surface of metal measuring diaphragm (elastic measuring element) of different thickness by isolating diaphragm and conducting pressure.

Rosemount pressure transmitter working principle of metal capacitive pressure (gauge) / absolute pressure transmitter is that when the pressure acts indirectly on the surface of metal measuring diaphragm (elastic measuring element) of different thickness by isolating diaphragm and conducting pressure, the diaphragm produces small deformation, the maximum shape variable is not more than 0.1 mm, and the high precision measuring circuit converts this small deformation into a voltage signal linearly related to the differential voltage signal. After linearization and temperature compensation, the voltage signal is converted into an industrial standard 4-20mA current signal or 1 ≤ 5V voltage signal by using a special chip.
