Rosemount 3051 Coplanar Pressure Transmitter

Name: Rosemount 3051 Coplanar Pressure Transmitter – Manual
Brand: Rosemount

Description

Overview

The Rosemount 3051 Coplanar Pressure Transmitter combines advanced technology with the versatile Coplanar process connection to create a proven standard in pressure measurement. With over 10 million devices installed worldwide, the Rosemount 3051 offers an all-in-one solution for pressure, level, and flow measurement, and an upgraded transmitter design helps maintenance teams commission, troubleshoot, and service devices faster than ever.

Working closely with plant engineers in the region, Seven Star LLC proudly offers the Rosemount 3051 Coplanar Pressure Transmitter to oil and gas, chemical, and power generation facilities across the Sultanate of Oman, Muscat, and the wider GCC. Its patented Coplanar technology allows direct mounting in multiple measurement applications, giving plant engineers a proven, field-tested instrument backed by decades of installed history and a broad base of trained maintenance technicians already familiar with its configuration and diagnostics.

Measurement Principle

The Rosemount 3051 delivers 10-year installed stability and 150:1 rangedown, producing reliable pressure measurements across a wide range of application conditions. The Coplanar transmitter design uses two pressure-sensing isolating diaphragms to enable differential pressure measurement, while the coplanar form also allows greater installation flexibility with assembly to various process flanges, manifolds, remote seals, and DP flow primary elements.

Application-specific configuration allows the transmitter to be transformed into a flow meter with a totalizer, or a level transmitter with volume calculations, giving operators flexibility to repurpose the same base instrument across different measurement roles as plant needs evolve. Complete pressure, level, or flow assemblies are leak-tested and calibrated at the factory to reduce leak points by up to 70% and simplify field installation, cutting commissioning time on multi-transmitter projects where dozens of loops must be checked out on a tight schedule.

Engineering Design of the Rosemount 3051

The Rosemount 3051 features a graphical, back-lit display that allows easy operation in 8 different languages under all lighting conditions, with visual icons giving improved insight into transmitter status. Optional Bluetooth wireless connectivity unlocks a far simpler maintenance and service process, letting technicians access calibration and diagnostic data without a physical connection to the device.

The 3051 can utilize either traditional flanges or Rosemount’s versatile Coplanar platform, arriving factory calibrated, pressure-tested, and ready to install. The transmitter is available in a number of materials and a wide range of hazardous area certifications, and is SIL 2/3 certified to IEC 61508 via an independent third party, with prior-use FMEDA data available for safety instrumented system installations.

Why Choose Seven Star LLC for the Rosemount 3051 Transmitter

With more than 10 million 3051 units installed worldwide, most Oman-based plants already have legacy 3051 transmitters somewhere on site – the practical sourcing question is usually whether a replacement unit should match the existing Coplanar mounting and output protocol exactly, or whether it’s a good opportunity to add Bluetooth connectivity or SIL certification during a planned upgrade. Seven Star LLC’s engineers walk customers through that decision before quoting, confirming flange compatibility, hazardous-area certificates, and protocol (4-20mA HART, Profibus, or FOUNDATION Fieldbus) against the existing loop so the replacement drops straight into service. For SIL 2/3 safety-loop applications we also help assemble the FMEDA and prior-use documentation the customer’s functional safety file requires, and we coordinate delivery timelines around planned turnarounds across Muscat, Sohar, and the broader GCC so a transmitter swap doesn’t extend an outage.

About brand

Rosemount is Emerson's brand for pressure, temperature, level and flow measurement, best known for the 3051 pressure transmitter. Frank Werner, Robert Keppel and Vernon Heath founded it in Minnesota in 1956 as Rosemount Engineering Company, first making temperature sensors for aerospace. It moved into the process industries, took the name Rosemount Inc. in 1966, and has been part of Emerson since 1976.

Seven Star LLC is an independent supplier in Muscat. We list Rosemount transmitters, level instruments, flowmeters and analytical sensors, and supply them and their spares to oil and gas, power, water and process plants in Oman and the GCC by model code.

Many Rosemount transmitters share one platform, so the model code tells you what you have. On a 3051, the letter after the number sets the type: C for coplanar (differential or gauge), T for in-line, L for liquid level and CF for a complete flowmeter. The next characters set the measurement type, the range code, the output (4-20 mA HART, FOUNDATION Fieldbus or WirelessHART) and the wetted materials. A transmitter with the wrong range code may work, but with poor accuracy at the point that matters.

Where Rosemount instruments are used

In Oman and the GCC, Rosemount instruments are used across upstream oil and gas, gas plants and LNG, refineries, tank farms and terminals, power and desalination stations, and water networks. Ultrasonic gas meters and tank gauges are used for fiscal and custody transfer measurement.

Ordering Rosemount instruments: what we need

Send the full model code from the nameplate (for example 3051CD2A22A1AM5B4) and the tag if it is a replacement. For a new instrument, send the measuring range, process connection, wetted materials, output protocol and hazardous area approval.
