Measuring principle:
Pressure transmitter measurement is primarily based on the deformation characteristics of the diaphragm. When the process pressure changes, the fill fluid transfers the pressure to the Wheatstone resistance bridge, converting the deformation of the sensing element into an electrical signal. The electrical signal is transmitted through wires to the amplifier for amplification and signal processing, and is finally converted into a standard output signal (typically 4–20 mA) for communication with the control system.
