E&H PMP51 pressure transmitter

Product Overview

The Endress+Hauser Cerabar PMP51 is a digital pressure transmitter engineered for precise absolute and gauge pressure measurement in gases, steam, and liquids. Featuring a fully welded metal piezoresistive sensor, the E&H PMP51 pressure transmitter delivers exceptional reliability in demanding process environments, including high-pressure applications up to 400 bar (6000 psi)-2.

This smart transmitter is widely deployed across process industries and hygiene-sensitive applications for pressure, level, volume, and mass measurement. Its modular design, coupled with a quick-setup adjustable measuring range, significantly reduces commissioning time and operational costs-5.

The PMP51 series is succeeded by the newer PMP51B platform, yet the original PMP51 remains a widely stocked and specified solution for established installations and budget-conscious projects-65.
