Measuring principle:
The measurement principle of a pressure transmitter is primarily based on diaphragm deformation. When the pressure changes, the fill fluid transfers the pressure to a Wheatstone resistive bridge, which converts the deformation of the sensing element into an electrical signal. The electrical signal is transmitted through wires to an amplifier for signal amplification and is ultimately converted into a standard output signal, typically 4–20 mA, for communication with the control system.

Standard
Using scenario:
The Cerabar PMP75 digital pressure transmitter features a metal diaphragm seal and is primarily designed for process and hygienic applications. It can be used to measure the pressure, level, volume, and mass of liquids or gases. The transmitter is suitable for high-temperature and high-pressure applications, with a temperature range from -70 to 400 °C. The adjustable measuring range and quick setup help reduce costs and save time. The design complies with IEC 61508 and supports SIL 2/3 functional safety requirements.
