Rosemount 3144P Temperature Transmitter

Name: Rosemount 3144P Temperature Transmitter – Datasheet & Quote
Brand: Rosemount

Description

Overview

The Rosemount 3144P Temperature Transmitter provides superior accuracy, stability, and reliability, making it the industry-leading temperature transmitter used in critical control and safety applications. Available with either 4-20mA/HART or completely digital FOUNDATION Fieldbus protocol, the 3144P accepts either single-sensor or dual-sensor inputs, with dual-sensor capability enabling differential temperature measurement, averaging temperature, or redundant temperature measurement from two independent sensors.

Backed by manufacturer datasheet documentation, Seven Star LLC proudly offers the Rosemount 3144P to oil and gas, petrochemical, pharmaceutical, and utility facilities across the Sultanate of Oman, Muscat, and the wider GCC. The HART version of the 3144P is approved for use in Safety Instrumented Systems, with third-party validated metrics tested per IEC 61508, giving safety engineers confidence in critical temperature monitoring loops where an undetected sensor failure could otherwise go unnoticed until the next scheduled proof test.

Measurement Principle

The Rosemount 3144P can be configured for a variety of sensor inputs, including RTD, thermocouple, millivolt, or ohm, with support for 2-, 3-, and 4-wire RTD configurations. Accuracy reaches ±0.18°F for Pt100 RTD inputs, delivered through 3 analog inputs and 1 input selector, with a 9.0 to 32VDC supply drawing a maximum of 11mA.

The Transmitter-Sensor Matching feature eliminates interchangeability error, improving accuracy by 75% by trimming the transmitter to the specific sensor’s Callendar-Van Dusen calibration constants. Sensor Drift Alert continuously monitors the differential temperature between two sensors; when one sensor drifts and the differential exceeds defined limits, the user is alerted to an unreliable measurement before it affects process control.

Engineering Design of the Rosemount 3144P

The Rosemount 3144P features a dual-compartment housing that isolates the electronics and terminal compartments, protecting sensitive electronics from field wiring disturbances. The Hot Backup feature reduces the risk of losing important temperature measurements by 80%, automatically switching the measurement to a backup sensor if the primary sensor fails—a critical safeguard for continuous process control loops.

Meeting NAMUR NE 21 recommendations, the 3144P ensures top transmitter performance in harsh EMC environments, while the HART version additionally meets NAMUR NE 43 and NE 89 recommendations. High-performance diagnostics available with both HART and FOUNDATION Fieldbus communication provide continuous measurement status (good, bad, or uncertain) and sensor failure indication, with performance information available to AMS asset management software, letting instrument technicians triage a drifting sensor from the control room rather than dispatching a field visit first.

Key Features

The Rosemount 3144P combines dual-sensor flexibility with industry-leading accuracy and diagnostics. Core capabilities include:

Single- or dual-sensor input supporting RTD, thermocouple, millivolt, or ohm sensor types.
±0.18°F accuracy for Pt100 RTD inputs.
Transmitter-Sensor Matching improving accuracy by 75% by eliminating interchangeability error.
Hot Backup feature reducing risk of measurement loss by 80% via automatic sensor switchover.
Sensor Drift Alert for continuous monitoring of dual-sensor differential temperature.
HART version approved for use in Safety Instrumented Systems (IEC 61508 tested).
Dual-compartment housing isolating electronics and terminal wiring compartments.
Compliant with NAMUR NE 21, NE 43, and NE 89 recommendations for EMC and diagnostics.

Industrial Applications

The Rosemount 3144P is well suited to oil and gas processing, petrochemical facilities, pharmaceutical manufacturing, food and beverage production, and utility plants across Oman requiring precise, reliable temperature measurement in critical control and safety loops. Its dual-sensor and Hot Backup capabilities make it especially valuable in processes where continuous temperature visibility cannot be interrupted, such as reactor jacket monitoring or fired-heater tube-skin temperature loops.

Working closely with plant engineers in the region, Seven Star LLC supports refineries, petrochemical plants, and utilities throughout the Sohar and Salalah economic zones and the broader GCC region with the Rosemount 3144P’s industry-leading temperature measurement reliability.

Why Choose Seven Star LLC for the Rosemount 3144P Temperature Transmitter

Temperature loops feeding a Safety Instrumented System carry documentation requirements that go beyond the transmitter itself – IEC 61508 certificates, Transmitter-Sensor Matching records, and Hot Backup configuration all need to be verifiable during a SIL audit. Seven Star LLC’s engineers help customers assemble that documentation package alongside the 3144P order, and confirm sensor type (RTD, thermocouple, millivolt) and wiring configuration (2/3/4-wire) against the existing junction box before shipment, avoiding a field rewiring exercise. Because dual-sensor and Hot Backup configurations are often specified for critical loops that cannot tolerate a measurement gap, we also plan spare-sensor and spare-transmitter stock so a failed primary sensor can be swapped without waiting on a fresh import, and we support customers across Oman’s refining, petrochemical, and utility sectors with regional delivery timed to planned maintenance windows.

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.
