PMD3051GP/GA Pressure (gauge) / absolute pressure transmitter is a pressure signal measured by atmospheric pressure / vacuum as the reference end, with only one port connected to the process pipe. The 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.
The high precision integrated circuit adopted by the high sensitivity of the metal capacitance pressure sensor and the measuring diaphragm detection circuit contains the linear and temperature compensation circuit inside, so the whole transmitter can achieve high precision and high stability. Metal capacitive pressure sensor has high overload resistance and excellent performance in micro-pressure measurement, and it is also a necessary product in a variety of complex industrial environment.
