Endress Hauser Cerabar PMP51B Pressure Transmitter

Core Performance & Industrial Application

The Endress+Hauser Cerabar PMP51B is a smart absolute and gauge pressure transmitter with a welded metal membrane for liquids and gases.

It covers a measuring range from 400 mbar to 400 bar (6 to 6000 psi) with up to 100:1 turndown.

It outputs 4-20mA HART signal and supports PROFINET over Ethernet-APL, with optional Bluetooth and SmartBlue App remote operation.

Reference accuracy reaches ±0.055% (Platinum version) with 0.1% URL/year long-term stability.

It carries SIL safety certification and ATEX / IECEx hazardous-area approvals for process safety loops.

It is widely used as spare replacement in chemical, oil & gas, pharmaceutical and food process pressure monitoring.
