3051 pressure transmitter

product manual:

       1. Working principle

       During operation, the isolation diaphragms and filling fluid on the high and low pressure sides transfer the process pressure to the filling fluid, and then the filling fluid transfers the pressure to the sensor diaphragm of the sensor. The sensing diaphragm is a tensioned elastic element whose displacement changes with the pressure (for GP gauge pressure transmitters, atmospheric pressure is the same as applied to the low pressure side of the sensing diaphragm). AP absolute pressure transmitter, the low pressure side always maintains a reference pressure. The displacement of the sensing diaphragm is 0.004 inches (0.1 mm), and the displacement is proportional to the pressure. Capacitor plates on both sides detect the position of the sensing diaphragm. The difference in capacitance between the sensing diaphragm and the capacitor plate is converted into a corresponding current, voltage or digital HART (High Speed Addressable Remote Transmitter Data Highway) output signal.
