Tasks that were a pain in the neck for decades must be difficult forever, right? Nope. They just pummel victims into believing a solution isn’t possible, until a forceful alternative sets everyone free.
For instance, temperature measurement in process applications was always problematic because it required piercing pipelines, and inserting probes and sensors to examine process streams. These difficulties also make it hard to maintain measuring points and readings, which not only threatens production, but can even push users to replace sensors, thermowells and other components they think might be failing before their measurements degrade.
To smooth the temperature measurement experience and cure these persistent headaches, Emerson has launched the Rosemount 3144S temperature transmitter that provides high accuracy, flexibility, stability, and greatly expanded usability. These multiple talents let it overcome many temperature measurement hurdles, allowing users and their process applications to run more efficiently, safely and profitably.
“Temperature measurement has always faced many obstacles, while promises to remove them went unfulfilled. Rosemount 3144S addresses these problems by giving users actionable insights long before measurements and devices fail,” says Ryan Leino, senior product manager for Emerson’s temperature transmitter portfolio. “We also focused on ease of use because there are many more retirements and much less experience in many process plants lately, and the younger generation replacing them wants equipment that’s easy to interact with and learn.”
Rosemount 3144S’s ease-of-use highlights include Bluetooth wireless networking that lets users connect to their devices securely within 50 feet, allowing them to perform troubleshooting, configuration and other tasks. It also has an intuitive, backlit, graphical operator interface with a simpler, task-based menu structure. This HMI allows common navigation across host and configuration tools for 3144S and other Rosemount products. The temperature transmitter also features:
Quick Service buttons that allow local access to commissioning and maintenance tasks, such as viewing current configurations, performing loop tests, and rotating the display.
ReadyConnect grants further usability with plug-and-play sensor configuration via pushbutton, eliminating manual inputs of sensor data and Callendar-Van Dusen coefficients, which saves configuration and commissioning time and reduces possible errors.
Rosemount X-well non-intrusive, temperature measurement eliminates the need for thermowells, has doubled its application coverage, and can now measure up to 650 °C (1,202 °F) without pipe penetration.

To meet accuracy and stability requirements, Leino reports that Rosemount 3144S delivers industry-leading 0.05 °C (0.09 °F) accuracy, which is essential for processes requiring the highest available measurement performance. It’s also available with an optional 20-year stability specification and a 20-year limited warranty. “Rosemount 3144S is more accurate than any device in our temperature-measurement portfolio,” explains Leino. “And its 20-year stability means it’s not going to drift out of spec for 20 years or more, which is a four-fold increase compared to our present portfolio.”
Rosemount 3144S also provides full, sensor-to-control room diagnostics, including its Loop Integrity diagnostic and RTD Measurement Protection, which provide real-time insight into each measurement point to ensure confidence in every process. These tools include a suite of sensor-health diagnostics, dual input capabilities, and continuous electrical loop monitoring. Specifically, Loop Integrity performs continuous monitoring of the electrical loop to detect potential failures before they occur, while RTD Measurement Protection will seamlessly switch from a four-wire to a three-wire RTD sensor input configuration if one of the four sensor wires is broken, corroded or loose in any location from the sensor element to transmitter terminal connections.
“It’s important to understand that Rosemount 3144S doesn’t just provide actionable data on the sensor side,” adds Leino. “It also delivers proactive insights for its power supply and related functions. We’re monitoring different variables like electrical resistance that can indicate the relative health of the measurement point, and align its data with what’s happening in reality.
