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, where the deformation of the sensing element is converted into an electrical signal. The electrical signal is transmitted through wires to the amplifier for signal amplification and processing, and is finally converted into a standard output signal (typically 4–20 mA) for communication with the control system.
Product positioning:
Standard
Using scenario:
The Cerabar PMC71 digital pressure transmitter features an oil-free capacitive ceramic measuring cell and is mainly designed for process industries and hygienic applications. It is suitable for measuring the pressure of liquids and gases, as well as level, volume, and mass. The PMC71 uses a vacuum-resistant ceramic diaphragm to ensure high safety and reliability of the measuring system. With adjustable measuring ranges and fast setup functions, it simplifies commissioning while reducing installation costs and time. Designed according to IEC 61508 standards, it meets SIL2/3 functional safety requirements.
