Endress+Hauser Cerabar M PMP51-Q9F7/1K9 Pressure Transmitter

Endress+Hauser Cerabar M PMP51-Q9F7/1K9 Pressure Transmitter

The Endress+Hauser Cerabar M PMP51-Q9F7/1K9 is a digitally enhanced pressure transmitter that provides remarkable accuracy in the most challenging process conditions. This transmitter is designed for absolute and gauge pressure measurements of gases vapours and liquids with a rugged metal isolation diaphragm.

The PMP51 series is designed for ease of use and safety, and may be easily integrated into marine automation systems, processing plants and heavy industrial machinery. Its sturdy design assures long-term calibration stability and excellent reproducibility. Your machinery parameters remain safely in operational limits, even under strong cycle pressure loads.

Model Details:

Brand: Endress+Hauser

Product Line: Cerabar M

Model Number: PMP51-Q9F7/1K9

Country of Origin: Germany

Features and Benefits

1. High Precision Metal Membrane The innovative metallic welded cell minimises thermal hysteresis and ensures a maximum overpressure limitation up to 4x nominal pressure.
2. SIL 2 Safety Certified: Independent TÜV NORD verification that meets the rigorous IEC 61508 safety requirement for hazardous process monitoring processes.
3. Tool-Free Commissioning: Convenient menu-driven local display for fast on-site commissioning without the need for specialised configuration software.
4. Exceptional Turn Down (100:1): Operators can recalibrate and downscale measuring span with baseline precision.
5. Modular Platform Architecture: Internal components are common to the Deltabar and Deltapilot lines and save spare parts stocking expenses on board or in-facility.

Where to Use?

• Fuel oil booster modules, lubricating oil systems and main engine cooling water lines are under critical supervision in maritime engine room systems.
• Hydrostatic Level Sensing: Precise determination of the volume and the mass of liquids in settling lines, ballast tanks and cargo tanks.
• Steam Plant Monitoring Control of high temperature steam and boiler feed water pressures in marine propulsion plants and utility plants.
• Chemical and Process Engineering: Surveillance of high-pressure process vessels and distribution networks for corrosive gases.

Installation and Maintenance Guide:

1. Vibration Mitigation: While the PMP51 is highly resistant to mechanical vibration, always check your mounting brackets on high-vibration machinery (like auxiliary diesel fuel blocks). If necessary, utilize a remote capillary setup to isolate the transmitter body.
2. Thread Assembly Sealing: When installing the standard NPT threads into your header lines, ensure you apply premium-grade Teflon tape or marine-approved thread compound. Torque to a maximum of 7 Nm(5.16 lbf .ft) to prevent microscopic thread deformation.
3. HART Loop Check Validation: Take advantage of the 4-20mA HART protocol during dry-dock or scheduled maintenance turnarounds. You can force loop currents directly from the device display module to test your automated shutdown valves (ESD) without needing external pressure simulators.
