Absolute and gauge pressure Cerabar S PMC71

Digital pressure transmitter with oil-free ceramic sensor for measurement in gases or liquids

The Cerabar PMC71 digital pressure transmitter with capacitive, oil-free ceramic measuring cell is typically used in the process and hygienic applications for pressure, level, volume or mass measurement in liquids and gases. It guarantees high degree of system safety thanks to vacuum-proof ceramic membrane with integrated breakage detection. Quick Setup with adjustable measuring range allows simple commissioning, reduces costs and saves time. SIL2/3 according to IEC 61508.

Benefits
