Cerabar PMC51B Pressure Transmitter

Name: Cerabar PMC51B Pressure Transmitter – Manual & Price Quote
Brand: Endress+Hauser (E & H)

Description

Overview

The Cerabar PMC51B is Endress+Hauser’s smart pressure transmitter from the new Cerabar generation, featuring a ceramic process membrane for highly accurate measurement of liquids and gases. It combines robustness with easiest local or remote operation and condition-based maintenance, promoting better management of scheduled plant shutdowns through its intuitive, wizard-guided commissioning software.

Working closely with plant engineers in the region, Seven Star LLC proudly offers the Cerabar PMC51B to oil and gas, chemical processing, and water treatment facilities across the Sultanate of Oman, Muscat, and the wider GCC. The transmitter can be remotely controlled via the SmartBlue App on a mobile device through a secure Bluetooth connection, allowing wireless commissioning and diagnostics in the process area without process interruption.

Measurement Principle

The Cerabar PMC51B uses a Ceraphire ceramic process membrane to measure absolute and gauge pressure across a range of 100 mbar to 40 bar (1.5 to 600 psi), with a smallest calibratable span of just 5 mbar (0.075 psi) and a maximum turn-down ratio of 100:1. Reference accuracy reaches up to 0.075% in the standard version and up to 0.055% in the Platinum variant, with long-term stability of 0.10% of URL per year.

Being dry and oil-free, the ceramic measuring cell offers vacuum resistance down to 0 mbar absolute and is fully vacuum-resistant up to +100°C process temperature, making it well suited to demanding vacuum and gas applications where fill-fluid-based transmitters would be unsuitable. The device supports 4-20mA analog, 4-20mA HART, and PROFINET over Ethernet-APL communication.

Engineering Design of the Cerabar PMC51B

The Cerabar PMC51B operates across a process temperature range of -40°C to +100°C and an ambient temperature range of -40°C to +85°C, with a maximum overpressure limit of 60 bar (900 psi). Process connections include threaded types (G1/2 to G2, R1/2, MNPT1/2 to MNPT2, FNPT1/2) as well as flanged connections from DN25 to DN80 (NPS 1″ to 4″).

The transmitter’s aluminium housing is rated for supply voltages of 10.5 to 35V DC (Ex d, Ex e, non-Ex) or 10.5 to 30V DC (Ex i), with wetted seal materials including FKM, EPDM, HNBR, Perlast, and Kalrez to suit a wide range of process media. Bluetooth wireless technology, an RFID TAG for easy identification, and plug-and-play functionality round out the device’s smart instrumentation feature set, alongside SIL2 safety-rated commissioning per IEC 61508/IEC 61511.

Industrial Applications

The Cerabar PMC51B is well suited to oil and gas, chemical processing, power generation, and water treatment facilities across Oman requiring accurate, hazardous-area-rated process and level pressure measurement. Its SmartBlue App wireless operation is particularly valuable for reducing on-site accidents and protecting personnel when instruments are installed in difficult-to-reach areas of a plant.

With fast quotation turnaround and technical support, Seven Star LLC supports refineries, chemical plants, and water utilities throughout the Sohar and Salalah economic zones and the broader GCC region with the Cerabar PMC51B’s proven smart pressure measurement platform.

Why Choose Seven Star LLC for the Cerabar PMC51B

A ceramic-membrane pressure transmitter is the right choice for many process media, but the wetted seal material, process connection thread, and hazardous-area certificate all need to match the actual installation – ordering a standard non-Ex housing for a Zone 1 area, or the wrong seal material for an aggressive fluid, is a common and avoidable mistake. Seven Star LLC’s engineers confirm process media compatibility, connection type, and Ex certification requirements with the customer before the PMC51B is ordered, and help plan SIL2 loop documentation for facilities building an IEC 61511 safety case. We also support commissioning via the SmartBlue Bluetooth app so technicians across Muscat, Sohar, and Salalah can verify configuration remotely, and coordinate delivery of drinking-water-approved variants for utility customers needing NSF or KTW compliance documentation.

About brand

Endress+Hauser makes process measurement instruments for flow, level, pressure, temperature and liquid analysis. Georg H. Endress and Ludwig Hauser started the business in Lörrach, Germany, on 1 February 1953, first selling level meters, and the Endress+Hauser name has been used since 1957. The group is headquartered in Reinach, Switzerland, and has been wholly owned by the Endress family since 1975.

Where Endress+Hauser instruments are used

In Oman and the GCC, Endress+Hauser instruments are common in oil and gas production and processing, refineries and petrochemicals, desalination and water networks, wastewater treatment, power plants and food and beverage plants. Coriolis meters measure hydrocarbon and chemical flows, electromagnetic meters cover water and wastewater, radar transmitters handle tank and silo level, and Liquiline analysers monitor water quality. Proline 300 and 500 flowmeters include Heartbeat Technology for in-situ verification, which reduces the need to remove a meter for checks.

Ordering Endress+Hauser instruments: what we need

The order code on the nameplate (for example PMP71-1QA1S11RDADU) defines every option: measuring range, process connection, materials, output, approvals and display. Send it with the serial number; Endress+Hauser can retrieve the original configuration from the serial number. For a new instrument add the medium, operating and design pressure and temperature, range, line size or tank geometry, process connection, wetted materials, output or protocol (4-20 mA HART, PROFIBUS, FOUNDATION Fieldbus, Modbus) and the hazardous-area approval required. Older models such as Promass 80/83 or Micropilot M are replaced by current Proline or 80 GHz Micropilot devices.
