Frequently Asked Questions
Understanding high-performance pressure measurement
What distinguishes PMP7x high-performance from standard PMP5x?
Cerabar PMP7x adds premium features: enhanced accuracy (±0.025%), faster response time (45ms), extended diagnostics with Heartbeat Technology, multi-variable output, advanced communication protocols, and custody transfer approvals for critical applications.
What accuracy levels do high-performance transmitters achieve?
PMP7x achieves ±0.025% reference accuracy with premium calibration, thermal compensation to ±0.05% per 10°C, and long-term stability ±0.05% per year. Optional platinum resistance thermometer provides ±0.1°C temperature accuracy.
What is HistoROM and how does it benefit operations?
HistoROM is non-volatile memory storing complete transmitter history: calibration records, configuration changes, event logs, min/max values, and operating hours. This data survives power loss and enables audit trails, failure analysis, and configuration backup.
Can PMP7x transmitters perform local calculations?
Yes, PMP7x includes powerful calculation capabilities: flow calculation from differential pressure, level calculation with density compensation, totalization, custom linearization tables, and mathematical functions. This distributed intelligence reduces controller loading.
What advanced communication protocols do PMP7x support?
PMP7x supports all major protocols: HART 7 with burst mode, PROFIBUS PA with profile 3.02, Foundation Fieldbus with function blocks, Modbus RTU/TCP, and new Ethernet-APL for industrial ethernet. Multiple variables transmitted simultaneously.
How does PMP7x support functional safety (SIL)?
PMP7x achieves SIL 2 (single) and SIL 3 (redundant) per IEC 61508. Features include safe failure fraction >90%, proof test coverage >99%, comprehensive diagnostics per NAMUR NE43, and hardware fault tolerance. Heartbeat enables partial proof testing.
What makes PMP7x suitable for custody transfer?
PMP7x meets custody transfer requirements through certified accuracy ±0.025%, approvals per OIML R117 and API MPMS, long-term stability, tamper-evident configuration, and complete audit trail. Accepted by weights and measures authorities globally.
Can PMP7x measure both static and dynamic pressure?
Yes, PMP7x excels at both: exceptional stability for static pressure measurement and 45ms response capturing pressure transients. Advanced filtering separates components. Fast electronics enable pressure signature analysis for pumps and leak detection.
