From the outside, the 3051GP pressure transmitter has only one interface. The main structure of the pressure transmitter is the sensor and the housing and dial. The appearance of the 3051GP pressure transmitter is very similar to that of the differential pressure transmitter. It follows the technology of the traditional capacitive transmitter and adds new functions such as communication. When installing, make sure that there is no strong electromagnetic interference around.

What is the working principle of the WE3051 series metal capacitive pressure transmitter?
A measuring diaphragm and electrodes on either side of the insulating sheet, which together form a capacitor, make up the pressure transmitter. The measuring diaphragm shifts when there is uneven pressure on both sides. When the capacitances on the two sides are not identical, the displacement will be modified through the oscillation and demodulation linkages since it is proportional to the pressure difference.
