Absolute and manometric pressure Cerabar PMC51
Digital pressure transmitter with oil-free ceramic sensor for measurement in gases or liquids
The Cerabar PMC51 digital pressure transmitter with a capacitive oil-free ceramic measuring cell is typically used in technological and hygienic applications to measure pressure, level, volume or mass in liquids and gases. It guarantees a high degree of system safety thanks to a vacuum ceramic membrane with integrated breakage detection. Quick setup with an adjustable measuring range makes it easy to put into operation, reduces costs and saves time. SIL2 in accordance with IEC 61508 /IEC 61511.
