Overview

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.


Benefits

  • Best accuracy, reproducibility and long-term stability

  • Highest safety due to gas tight feedthrough with capabilities up to SIL2/3, certified to IEC 61508

  • Easy menu-guided commissioning via local display, 4 to 20mA with HART, PROFIBUS PA, FOUNDATION Fieldbus

  • HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics

  • Overload-resistant and function-monitored from the measuring cell to the electronics

  • Available with mounted manifolds: always fit, always tested for leaks

  • Seamless and independent system integration (HART/PA/FF)


Application

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)

  • Accuracy: ±0.05%, "Platinum" ±0.025%

  • International explosion protection certificates, overfill prevention WHG, hygienic approvals, marine approvals, SIL
