Absolute and gauge pressure Cerabar PMP71,predecessor is PMP731

Digital pressure transmitter with welded metal sensor for measurement in gases, steam or liquids

The Cerabar PMP71 digital pressure transmitter with metallic membrane is typically used in process applications for pressure, level, volume or mass measurement in liquids or gases. PMP71 is designed for high pressure applications up to 700bar. Quick Setup with freely adjustable measuring range without pressure specification. Designed according to IEC 61508 for use in SIL2/3 safety systems and available with MID Parts Certificate suitable for custody transfer applications.
