An Alternative to Traditional Temperature Measurement Solutions

Jim Cahill — Thu, 21 Sep 2023 16:19:46 GMT

In our four-part series on temperature measurement, we have reviewed the basics of temperature measurement, the value of using a temperature transmitter, and the ins and outs of a thermowell. In this blog, which is the last in the series, we examine an alternative solution for situations where traditional thermowells may not be the best temperature measurement option.

Monitoring process temperatures is one of the most common and valuable actions taken during production. It helps operators maintain a safer working environment and helps with determining process efficiency and product quality.

Traditionally, thermowells have been the go-to solution for many manufacturers. However, thermowell installation isn’t always an easy or timely process. While installing a thermowell isn’t typically difficult, the areas where they are needed are often inconvenient to reach, have pressurized lines, and offer little extra space for additional hardware. Depending on the individual setup, production may need to be halted entirely for the duration of the installation, causing manufacturers to lose time and money.

Emerson offers a solution to traditional thermowells with Rosemount™ X-well™ Technology, which handily addresses the challenges that are characteristic of other traditional process temperature measurement methods.

Traditional Surface Measurement Tools

Surface measurement tools are more easily installed than most other methods. There’s often no need to shut production down because they can be installed in difficult areas and without penetrating pressurized pipes. This helps eliminate potential structural damage and leak points. However, traditional surface measurement models are often incapable of providing accurate or repeatable internal process temperature measurements in every environment.

The relationship between surface temperature and process temperature is greatly dependent on the difference between ambient temperature and internal process temperature. Traditional surface measurement tools often apply a uniform correction to surface temperature measurements to counter anticipated changes. They should also consider the thermal conductivity of the measurement installation. However, the accuracy of a surface measurement tool reading can become questionable if either the process or ambient temperature changes.

How Rosemount X-well Technology Is Superior

Since so many factors can impact a traditional surface temperature measurement reading, Rosemount X-well Technology was developed to counter traditional measurement barriers.

More Accurate Measurements

Rosemount X-well Technology implements a heat flux algorithm that understands the thermal conductive properties of the temperature measurement assembly and corresponding piping or vessel, along with a surface temperature sensor solution that accurately calculates internal process temperature. This means it measures ambient temperature and the pipe surface, then runs those measurements through a thermal conductivity algorithm to calculate process temperature.

To ensure the most accurate temperature measurement, a Rosemount X-well solution requires three basic considerations: pipe diameter, pipe schedule, and pipe material. Because Rosemount X-well Technology accounts for the thermal conductive properties of the pipe and assembly, process temperature measurements are typically more accurate than those taken utilizing traditional surface measurement tools. This makes it an ideal solution for steady state applications.

Easy Installation

Rosemount X-well Technology can be installed without shutting down the production process and typically does not require a skilled contractor. A standard pipe clamp procedure and ordinary hand tools are sufficient tools for most installations. As an alternative to traditional pipe mounts that can be heavy and awkward to install, the latest version uses a unique Universal Pipe Mount design that utilizes a cut-to-fit banding solution. Unlike static mounting solutions that can lose contact with the pipe due to vibrations and pipe expansion or contraction due to process temperature fluctuation, the Universal Pipe Mount has an integral spring assembly, along with a spring-loaded RTD. This allows for process fluctuations while still maintaining solid contact with the outside of the pipe.

Increased Safety and Reduced Costs

Not only is Rosemount X-well Technology easy to install and use, but it can help operators save money on installation and maintenance. It also adds and enhances safety systems in the workplace.

Minimal failure risks mean Rosemount X-well Technology helps keep process production moving safely. Because it’s mounted to the pipe surface with the Universal Pipe Mount solution, the pipe structure is not compromised, helping reduce leaks and weak points on pressurized lines. This increases employee safety, especially in volatile and hazardous environments.

Operators save money initially because system design and installation do not require the added expense of hiring an engineer, specialized technician, or welder. Neither does making late changes or additions to the design. Rosemount X-well Technology also requires less maintenance than traditional surface measurement methods, saving operators money on labor costs, as well as expenses associated with production downtime.

Wireless Temperature Flare Header Monitoring

Jim Cahill — Wed, 31 May 2023 13:17:44 GMT

Rosemount X-well Technology measures the ambient and pipe surface temperatures to calculate process temperature via a thermal conductivity algorithm.

At the 4C Heath, Safety & Environmental Conference, Marathon’s Larry Stumbo and Emerson’s Marcio Donnangelo presented Flare Header Monitoring – Marathon Puts Non-Intrusive WirelessHART Transmitter in Temperature Monitoring. Here is their presentation abstract:

Marathon Petroleum saw the X-well as a new technology for creating Digital Transformation value across their fleet and determined a trial was in order. The goal was to test the reliability of a best-practice WirelessHART installation to see just how well it performed as compared to traditional temperature measurements. Installations were made and tested in four different and challenging applications at one of their cold-weather refineries over a period of one year. With many critical temperature measurements often needing to be added to improve refinery efficiency, the X-well’s ability to be installed with no process penetrations or thermowell, no field wiring, and no added analog input points at the DCS was attractive. Will the X-well pass the test in the real world for Marathon?

Marcio opened by describing the Rosemount X-well temperature measurement technology. It’s a wireless device that communicates via WirelessHART. It does not require a pipe penetration but rather straps externally to the pipe and performs the analysis to determine the temperature of the fluid inside the pipe.

Larry described why this technology was important for their trial. He has a maintenance background and traditional temperature measurements required a lot of maintenance on the thermowells from corrosion, erosion, and vibration. Installation was easy since no wires needed to be run. Given the northern U.S. location, they insulated around the piping where the X-well transmitters were installed.

One application was on cooling water. A regular temperature transmitter in a thermowell and the X-well were installed. The measurements closely tracked each other until there was a failure in the thermowell. Another example was a heat exchanger outlet. The results closely tracked each other until there was a wiring failure with the wired transmitter.

A third example was a flare gas header. The X-well tracked exactly with the referenced wired temperature transmitter. The X-well had a slight lag for the large piping in temperature reading behind the reference transmitter, but it was slight.

Overall, the testing showed the X-well wireless transmitter met almost all of their needs for temperature monitoring.

Visit the Rosemount X-well Technology section on Emerson.com for more information on how these temperature measurement devices provide accurate measurements without the complexities of thermowell installation and maintenance.

The Ins and Outs of a Thermowell

Jim Cahill — Thu, 30 Mar 2023 15:56:41 GMT

In our previous two blog posts relating to temperature measurement, we looked at an Introduction to Temperature Measurement and The Value of a Temperature Transmitter. This third blog post in this series on temperature measurement will focus on Thermowells. Thermowells are a mainstay in the process industry, but in order to be efficient and reliable, they require very careful calculations and specific designs.

Temperature sensors are rarely inserted directly into an industrial process. Instead, they are installed into a thermowell to isolate them from the potentially damaging process conditions of flow-induced stresses, high pressure, or corrosive chemical effects. The thermowell is installed in the pipe, and the temperature-sensing rod that covers the sensor is suspended in the process flow.

Emerson has four different thermowell stem profile options available: straight, stepped, tapered, and twisted. All have their reasons for use depending on the application, but let’s focus on the twisted design of the Rosemount™ Twisted Square™ Thermowell.

A New Twist on Thermowell Design

The Rosemount Twisted Square Thermowell’s unique twisted design is uniform for the entire length of the stem. This Rosemount patented design is exceptionally good at suppressing the harmful vortex-induced vibrations that a thermowell experiences in process applications. Compared to other thermowell designs, the Twisted Square will provide the most accurate and repeatable temperature measurements. The twisted design also allows for proper stem immersion in the pipe – close to 50% immersion is ideal – to ensure better accuracy. Learn more about the Rosem ount Twisted Square Thermowell here.

Eliminate the Biggest Thermowell Design Pain

We all know thermowell calculations are tedious and time-consuming to do manually, so we created a solution.

The Rosemount Thermowell Design Accelerator is a free online tool that accurately and quickly executes thermowell calculations. It’s easy to use and intuitively guides you through complex projects by helping you complete what used to take up to 50 hours in 15 minutes, saving you time and money.

The Accelerator can automatically iterate up to 1,000 thermowell tags, ensuring all are optimized for their process conditions and meet the latest ASME PTC 19.3 TW standards.

If thermowell tags do not to pass calculations and changes are necessary, the Accelerator will continue to iterate until it reaches a solution by automatically making changes to the dimensional parts of the thermowell. This helps you to avoid guess work and makes sure you always stay in compliance with the standards.

Once calculations are complete, you will receive valid Rosemount sensor and thermowell product models so you can avoid building model codes from catalogs or product data sheets and obtain error-free designs. The Accelerator also provides industry-standard required reports for full traceability and history of calculations performed to meet application requirements. Learn more about and try out the Rosemount Thermowell Design Accelerator here.

The Value of a Temperature Transmitter

Jim Cahill — Thu, 02 Feb 2023 16:47:44 GMT

Emerson’s Rosemount™ Temperature Transmitter portfolio provides solutions to meet the needs of most industrial applications.

Why Use a Temperature Transmitter?

The days of temperature transmitters only utilizing an analog signal are behind us. The evolution of technology, in particular, the microchip, has made it possible to create devices that are not only compact but also digital. No longer does it take a screwdriver and multi-meter to communicate with the temperature measurement device. Now it’s possible to hook up a laptop or tablet via a wired connection or wirelessly to get all the necessary temperature data from the transmitter.

A transmitter translates the signals from the temperature probe into accessible and actionable data for the technician. This data helps to optimize the process because changes can be quickly noted, and adjustments can be made to keep material flowing through the processing facility.

Let’s delve deeper into transmitters to learn more about the challenges of wired-direct installations, the purpose and advantages of transmitters, and the most current transmitter features, capabilities and onboard diagnostics available today.

The challenges of wired-direct installations

Historically, some users have preferred to implement wired-direct installations where they connect a thermocouple or RTD directly to a control system input without the use of a transmitter. While this may look prudent on the surface, this approach can add cost, complicate the installation and impact the performance of the measurement point. For example, the cabling from the sensor to the control system input card must match the sensor when wiring direct for the entire run of wiring. This can be costly, as sensor wiring is usually more expensive than standard copper wiring used with a transmitter installation. Wiring direct also has an impact on any changes done in the field. Changing a sensor type in the field requires changing the sensor and the entirety of the sensor wire run to match the new sensor type.

From a performance perspective, the small amplitude signal generated from a wired-direct thermocouple or RTD is susceptible to electrical interference, which can result in inaccurate measurements and possible process shutdown. Wired direct installations also lack any predictive diagnostics to minimize the effects of sensor degradation, resulting in a higher likelihood of unplanned shutdowns or other adverse impacts to the process.

The advantages of using transmitters

A transmitter offers a significant advantage over a wired-direct setup. Aside from reduced drafting time and wiring needs, a transmitter, sensor and thermowell assembly can be set to meet a specific performance goal, which can be arranged through a single vendor.

The industry-leading Rosemount 3144P Temperature Transmitter optimizes productivity, achieves faster start-up and safer operation, and increases operational efficiencies with enhanced field intelligence.

A temperature transmitter installation’s accuracy and performance are typically better than its wired-direct temperature counterpart due to it being far less susceptible to EMI and RFI interference. Low-level sensors tend to be highly vulnerable to EMI and RFI, particularly in cases where the extension cables act as antennas for noise signals. Transmitters can also filter out environmental noise and compensate for inaccuracies caused by corroded terminations and frayed wiring.

Higher performance is also possible with a transmitter-sensor assembly calibrated for specific performance goals and which better supports custody transfer and safety-related applications.

Wired-direct installations can also leave you prone to unexpected failures with minimal diagnostics coverage. Degraded or broken elements, loose or open connections, moisture in housings, frayed or damaged wiring, and electrical noise can all create risks for maintaining an accurate reading and keeping your process up and running.

Temperature transmitter diagnostics help you avoid measurement failure and process shutdown by identifying failing or degrading sensors and connections by monitoring and evaluating sensor loop resistance and sensor signal noise.

Transmitter features, capabilities and diagnostics

The Emerson Rosemount temperature measurement transmitters feature industry-leading accuracy, stability, and reliability with technological innovations to satisfy your temperature measurement needs.

Dual Compartment housing with HART®, WirelessHART®, or FOUNDATION™ Fieldbus output
Dual input capability with advanced diagnostics suite, including Hot Backup™, sensor drift alert, thermocouple degradation and min/max logging
Integral Transient protection, 5-year stability, SIL 2 certification
Large LCD display

Each feature is designed to make the transmitter easy to operate and reliable.

Available on the Rosemount 3144P transmitter, dual-compartment housing provides superior protection against environmental effects, such as EMI/RFI, humidity, corrosion, and water.

Of particular interest are the advanced diagnostics that allow an operator to troubleshoot the temperature probe or determine transmitter health.

In our upcoming third blog post in this series on temperature measurement, we’ll delve into thermowell basics, including the calculations needed to size them for an application and how the Rosemount Thermowell Design Accelerator can significantly simplify the thermowell design process.
