E+H Absolute and gauge pressure transmitter PMC71

Introduction
The Cerabar PMC71 digital pressure transmitter with capacitive, oil-free ceramic measuring cell is typically used in the process and hygienic applications for pressure, level, volume or mass measurement in liquids and gases. It guarantees high degree of system safety thanks to vacuum-proof ceramic membrane with integrated breakage detection. Quick Setup with adjustable measuring range allows simple commissioning, reduces costs and saves time. SIL2/3 according to IEC 61508.

Features
Best fit for vacuum applications and applications with corrosive and abrasive media
Process safety through membrane breakage detection
Overload-resistant high purity ceramic sensor (99.9% Al2O3)
HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics
Easy menu-guided commissioning via local display, 4 to 20mA with HART, PROFIBUS PA, FOUNDATION Fieldbus
Highest safety due to gastight feedthrough with capabilities up to SIL2/3, certified to IEC 61508
Available with mounted manifolds: always fit, always tested for leaks

The wide range of available process connections meets even special industrial requirements:
Threaded connections: e.g. for the power, pulp/paper, or oil and gas industries
Flange connections: e.g. for the chemical industry
Hygienic connections: e.g. for the pharmaceutical or food and beverages industries
