Description
This transmitter belongs to the new Cerabar generation. It combines robustness with numerous benefits: e.g easiest local or remote operation and condition-based maintenance which promotes better management of scheduled plant shutdowns.
The software is designed to simplify the handling. Intuitive and clear wizards guide you through the commissioning and proof testing of the device. The transmitter can be remotely controlled via app on a mobile device and a secure Bluetooth connection.
Pressure measuring range: up to 400 bar (6000 psi)
Process temperatures up to 400°C (752 °F) with diaphragm seal
Accuracy: up to +/- 0.055%
Features
Reduce systematic failures - error free SIL commissioning and instrument guided proof testing
Reduce on site accidents and protect equipment when instruments are in difficult to reach areas
Wireless control of the device in the process area with the SmartBlue App without process interruption

Why Choose the Endress+Hauser Cerabar PMP51B
Why Choose the Endress+Hauser Cerabar PMP51B
Value Elements
- Reliable Pressure Data for Natural Gas Operations
- The Cerabar PMP51B provides dependable pressure measurement for station control, equipment protection, alarms, and safe operation.
- It is a strong fit for Canadian natural gas compressor stations, regulating stations, meter skids, and remote pipeline assets.
- Flexible for Different Gas Applications
- The PMP51B can be configured for gauge or absolute pressure measurement, supporting both lower-pressure station monitoring and higher-pressure transmission or compression applications.
- Multiple process connection and material options make it easier to match site standards and gas service requirements.
- Built for Long-Term Field Confidence
- Long-term stability helps reduce unnecessary recalibration and supports more predictable maintenance planning.
- This is valuable for Canadian operators managing wide service areas, remote sites, and harsh seasonal conditions.
Comparison vs. Next Best Alternative
- Compared to a Basic Pressure Transmitter
- A basic transmitter may only provide a pressure output. The PMP51B adds stronger configuration flexibility, diagnostics, and digital integration options.
- This helps operators troubleshoot faster, standardize device handling, and improve visibility across multiple gas sites.
- Compared to Keeping Older Installed Devices
- Older transmitters may lack the communication, documentation, and verification support expected in modern gas facilities.
- The PMP51B offers a practical upgrade path for pressure regulation assemblies, compressor pressure points, and measurement skids.
Where Do I Use This Product and Why?
- Pressure Regulating Stations
- Use it to monitor inlet and outlet pressure around regulators, slam-shut valves, relief systems, and station piping.
- Compressor Stations
- Use it on suction, discharge, interstage, utility gas, and auxiliary pressure points where reliable feedback supports alarms, shutdown logic, and equipment protection.
- Metering and Pipeline Assets
- Use it where pressure input is needed for gas measurement, flow computer integration, remote monitoring, city gates, district regulator stations, and distribution assets.
