Endress+Hauser Cerabar PMC71B Pressure Transmitter

Name: Endress+Hauser Cerabar PMC71B – Price in Oman – Manual
Brand: Endress+Hauser (E & H)

Description

Overview

The Endress+Hauser Cerabar PMC71B is a digital pressure transmitter with a capacitive, oil-free ceramic measuring cell, the current-generation successor to the proven Cerabar S PMC71 platform. It is typically used in process and hygienic applications for pressure, level, volume, or mass measurement in liquids and gases, guaranteeing a high degree of system safety through its vacuum-proof ceramic membrane with integrated breakage detection.

With engineering support in Muscat, Seven Star LLC supplies the Endress+Hauser Cerabar PMC71B to process plants and industrial facilities across the Sultanate of Oman and the wider GCC, with manufacturer documentation and local technical support.

Measurement Principle

The Endress+Hauser Cerabar PMC71B measures pressure using a high-purity ceramic (99.9% Al2O3) capacitive sensing cell. Process pressure deflects the ceramic diaphragm, changing the capacitance between the diaphragm and a fixed electrode; this capacitance change is measured electronically and converted into a precise pressure reading with no oil fill required, eliminating the risk of fill-fluid leakage found in metallic-cell transmitters.

Because the ceramic sensor is inherently overload-resistant and corrosion-resistant, the Cerabar PMC71B performs reliably in vacuum service and with corrosive or abrasive media that would degrade other sensor technologies. The vacuum-proof membrane with integrated breakage detection provides an additional layer of process safety, alerting operators before a sensor failure can compromise the process.

Engineering Design of the Endress+Hauser Cerabar PMC71B

The transmitter covers pressure measuring ranges from 100 mbar to 40 bar, with process temperatures from –40°C to +125°C (up to +150°C in the high-temperature version) and an overpressure limit of 60 bar on the 40 bar cell. Process connections are available as threads and flanges, housed in a two-chamber aluminum or 316L stainless steel enclosure.

Communication is available via 4–20 mA HART, PROFIBUS PA, or PROFINET over Ethernet-APL, with menu-guided commissioning through the local display. The device is certified to SIL2/3 per IEC 61508, and HistoROM data management enables fast, easy commissioning, maintenance, and diagnostics throughout the instrument’s service life.

PMC71B Measuring Cells, Overload Limits and Accuracy

The Cerabar PMC71B is built around the oil-free Ceraphire ceramic cell, available in eight nominal ranges from 100 mbar to 40 bar for either gauge or absolute pressure. The overload capability is cell specific. The 40 bar cell has a maximum working pressure of 40 bar and an overpressure limit of 60 bar; the 10 bar cell is rated 26.7 bar and 40 bar, and the 1 bar cell 6.7 bar and 10 bar. All absolute cells are fully vacuum resistant down to 0 bar absolute.

Reference accuracy also varies with the cell. Cells from 1 bar to 40 bar reach ±0.05 % of the calibrated span up to a turn down of 10:1, while the 100 mbar and 250 mbar cells are specified at ±0.075 %. The Platinum option, valid up to a turn down of 5:1, delivers ±0.025 % on the 2 bar and 4 bar cells and ±0.035 % on most others. Long-term stability of gauge cells is ±0.05 % of the upper range limit after one year and ±0.10 % after ten years.

The standard device is rated for process temperatures from -40 to +125 °C. The +150 °C limit applies to the high-temperature version, which starts at -25 °C, and the permitted ambient temperature falls as process temperature rises above +85 °C. Seal choice narrows the range further: EPDM covers -40 to +125 °C, FKM -25 to +150 °C and Kalrez 6375 begins at +5 °C. For oxygen service the limit is 60 °C.

PMC71B Communication, Power Supply and Housing Variants

The PMC71B generation is offered with 4-20 mA HART, PROFIBUS PA or PROFINET over Ethernet-APL, each optionally with Bluetooth for the SmartBlue app. The HART version runs on 10.5 to 35 V DC, or 10.5 to 30 V DC as an intrinsically safe device. The display backlight and the Bluetooth function are switched off automatically when the supply is too low at power-on. PROFIBUS PA devices take 14 mA from a 9 to 32 V bus, and the Ethernet-APL version is an APL power class A device.

Three housings are available: a single compartment and a dual compartment housing in coated aluminium, and a dual compartment housing in cast 316L. All are tested to IP66/68 and TYPE 4X/6P. Devices with a 4-20 mA output have been developed to IEC 61508 for use up to SIL 3, and the Heartbeat Technology package provides on-demand verification and monitoring. Endress+Hauser names the Cerabar S PMC71 as the predecessor; the new device adds wizard-guided commissioning and proof testing.

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.
