Field of application

The Cerabar PMC51 is a digital pressure transmitter featuring a capacitive, oil-free ceramic measuring cell. It is commonly used in process and hygienic applications for measuring pressure, level, volume, or mass of liquids and gases. The vacuum-proof ceramic membrane with integrated breakage detection ensures a high degree of system safety. The Quick Setup with adjustable measuring range allows for simple commissioning, reducing costs and saving time. The Cerabar PMC51 is SIL2 certified according to IEC 61508 and IEC 61511.

Single chamber aluminum or stainless steel (316L) housing.
