Pre-Assembled Manifolds

Optional pre-assembled manifolds are pressure-tested and leakage-tested prior to shipment, accelerating field installation while ensuring proper sealing and operational readiness.

Field Serviceability Features

Zero/Span push-buttons for quick field recalibration

Test clamp for convenient loop testing without disconnecting wiring

RFID tag for electronic device identification and digital asset management

FLEX Modular Selection Concept

The PMP50 series aligns with Endress+Hauser’s FLEX modular selection framework, offering four pre-configured tiers:

Fundamental – Meet basic measurement needs

Lean – Handle core processes efficiently

Extended – Optimize processes with innovative technologies

Xpert – Master challenging applications

This modular approach enables precise specification matching of device capabilities to application requirements, preventing both over-specification and under-specification.

Application Scenarios

The Cerabar PMP50 pressure transmitter is engineered for standard industrial applications where reliability and accuracy are paramount. Typical deployments include:

Oil and Gas: Pipeline pressure monitoring, compressor station pressure measurement, wellhead pressure control

Chemical Processing: Reactor pressure monitoring, distillation column level measurement, storage tank pressure control

Power Generation: Boiler feedwater pressure monitoring, steam system pressure measurement, turbine inlet pressure control
