E+H Cerabar PMP51B High Accuracy Digital Pressure Transmitter
PMP51B-AABACBH6AA3FCA1VNJA1+VD
The Cerabar PMP51B is a high-performance digital pressure transmitter designed for precise gauge and absolute pressure measurement in industrial liquids, gases, and steam. Featuring a robust welded metallic diaphragm, Bluetooth remote commissioning, advanced SIL2 safety diagnostics, and optional Ethernet-APL integration, it guarantees exceptional long-term stability and process reliability across demanding chemical, oil & gas, and energy applications.
The Cerabar PMP51B digital pressure transmitter sets a new standard in process automation, offering high-precision measurement for absolute pressure, gauge pressure, liquid level, and mass in complex industrial environments. Engineered with a fully welded metallic isolating diaphragm and piezoresistive sensor technology, this smart pressure instrument delivers extraordinary accuracy up to ±0.055% of span, even under extreme process temperatures ranging from -40°C to +400°C (with diaphragm seals) and working pressures up to 400 bar.
Built for seamless digital integration, the PMP51B supports 4-20mA HART, PROFIBUS PA, and modern Ethernet-APL protocols, allowing operators to streamline device setup, monitor health status, and perform remote diagnostics using integrated Bluetooth technology via the SmartBlue app. Whether deployed in harsh chemical processing plants, oil refineries, power stations, or water management facilities, the PMP51B ensures long-term calibration stability with minimal drift, reduced maintenance costs, and maximum plant availability. Designed in accordance with IEC 61508 and IEC 61511 standards, its hardware and software architecture is SIL2 certified (SIL3 in homogeneous redundancy), providing top-tier functional safety and intuitive guided setup wizard for error-free commissioning.
FQA
Q: How does Bluetooth technology simplify the commissioning of the Cerabar PMP51B?
A: Integrated Bluetooth connectivity allows engineers to configure, commission, and perform diagnostics remotely from outside hazardous or hard-to-reach areas using the SmartBlue app on any smartphone or tablet, significantly reducing setup time and enhancing operator safety.
Q: What process media and conditions are best suited for the PMP51B metallic diaphragm?
A: The PMP51B is ideal for liquids, gases, and steam. Its piezoresistive metallic measuring cell with 316L or Alloy C276 diaphragms excels in high-pressure applications, high-temperature thermal shocks, and environments requiring flush-mounted hygienic fittings or diaphragm seals.
Q: Can the Cerabar PMP51B be integrated into Safety Instrumented Systems (SIS)?
A: Yes, the instrument is developed according to IEC 61508 / IEC 61511 and is certified for SIL2 single-use applications, as well as SIL3 in homogeneous redundant safety architecture.
