Cerabar M PMP55 - Digital Pressure Transmitter With Diaphragm Seal
Digital pressure transmitter with diaphragm seal for measurement
in gases, steams or liquids
The Cerabar PMP55 digital pressure transmitter with metal diaphragm seal is
typically used in the process and hygiene industry for pressure, level, volume
or mass measurement in liquids. PMP55 is designed for high pressure and high
temperature applications up to 400°C and 400bar. The Quick Setup with freely 
adjustable measuring range without pressure specification for simple commissioning
reduces costs and saves time. SIL2 according to IEC 61508 and IEC 61511.
