Absolute and gauge pressure Cerabar PMP71 Pressure Transmitter Field of application 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.
Two chamber aluminum or stainless steel (316L) housing. - Process connections: Threads and flange connections
- Process temperature: -40 to +125°C (-40 to +257°F)
- Measuring ranges: -1/0 up to 700bar (-15/0 up to +10,500psi)
