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

Standard
Using scenario:
Cerabar PMP71 digital pressure transmitter with a metal diaphragm is designed for process industries and is suitable for measuring the pressure of liquids and gases, as well as level, volume, and mass measurements. The PMP71 is specially developed for high-pressure applications, with a maximum operating pressure of up to 700 bar. It features fast setup functions and adjustable measuring ranges. Designed according to IEC 61508 standards, it meets SIL2/3 functional safety requirements. MID-certified versions are available for custody transfer measurement applications.
