Why Choose the Endress+Hauser Cerabar PMP71B

Value Elements
  • High-Performance Pressure Measurement for Demanding Gas Sites
    • The Cerabar PMP71B is a strong fit for Canadian natural gas applications where higher pressure capability, accuracy, and long-term signal confidence are important.
    • It supports gauge and absolute pressure measurement in gases, making it useful across transmission, compression, processing, and station control applications.
  • Built for Higher-Pressure Applications
    • Compared to the PMP51B, the PMP71B is better suited for more demanding pressure points, with available measuring ranges up to 700 bar / 10,500 psi.
    • This makes it a good choice for compressor stations, high-pressure transmission assets, process skids, and applications where pressure measurement is tied to equipment protection.
  • Smart Verification Without Process Interruption
    •  Heartbeat Technology allows device health verification while the process continues running, helping operators confirm transmitter performance without unnecessary shutdowns.
    • For Canadian gas operators managing remote or critical assets, this supports better maintenance planning and fewer avoidable site visits.

 

Comparison vs. Next Best Alternative
  • Compared to a Basic Pressure Transmitter
    • A basic transmitter may provide the pressure signal, but the PMP71B adds stronger diagnostics, verification capability, and digital communication options.
    • This helps natural gas operators move beyond simple measurement and improve confidence in pressure data used for alarms, controls, and maintenance decisions.
  • Compared to Lower-Duty Pressure Transmitters
    • The PMP71B is better suited for higher-pressure and more demanding services where accuracy, stability, and verification matter more than lowest installed cost.
    • It is a strong upgrade option when operators want a transmitter that supports modern reliability programs, not just basic pressure monitoring.

 

Where Do I Use This Product and Why?
  • Compressor Stations
    • Use it on suction, discharge, interstage, seal gas, utility gas, and auxiliary pressure points where dependable pressure data supports alarms, shutdown logic, and equipment protection.
  • Transmission and High-Pressure Gas Assets
    • Use it on high-pressure pipeline monitoring points, pressure control systems, block valve sites, and station piping where accurate pressure visibility is critical.
  • Metering and Process Skids
    • Use it where pressure input is required for gas measurement, flow computer integration, process control, and remote monitoring.
    • •It is especially useful where Canadian operators need a reliable pressure transmitter for critical or hard-to-access natural gas infrastructure.
