    Reducing Thermowell Dynamic Stress Forces

    Thermowells are traditionally a circular cylinder installed into the piping to protect the temperature sensors from the flow. From an Emerson whitepaper, Thermowell Calculations : As a process fluid passes around the thermowell, low pressure vortices are created on the downstream side in laminar, turbulent, and transitional flow. The combination of stresses, generated by the static in-line drag forces from fluid...

    Building IIoT—Temperature Measurement Style

    One quick example of the Industrial Internet of Things (IIoT) in action is temperature measurement. Traditionally, these measurements included piping or vessel penetrations, thermowells installed, RTD or thermocouple sensing elements and transmitters, wiring/fittings/junction boxes/conduit/cable trays/etc., marshalling panels and connections in the control system I/O. For critical temperature measurement and control this...

    Reduce Flow-Induced Thermowell Mechanical Stress

    Thermowells, as tubular fittings in pipes and vessels, provide protection for temperature measurement devices. As we highlighted in a post from several years back, New Thermowell Calculations Help Avoid Damaging Resonance , they are subject to the stresses and strains from the fluid flowing by. In a LinkedIn article by Emerson’s Timchan Bonkat , Rosemount Twisted Square Thermowell A New Twist in Thermowell Design...

    Instrumentation Diagnostics and Safe, Reliable Operations

    As technology has advanced in power and sophistication, its ability to self-diagnose and perform predictive diagnostics has too. In a Plant Engineering article, Using diagnostic functions to improve system safety , Emerson’s Mark Menezes shares examples of how these diagnostics are used to self-diagnose instrumentation problems as well as those in the surrounding production process. He opens highlighting the...

    Temperature Measurement and Wireless Device Instructional How-To Videos

    As we wind our way toward the holidays, I wanted to share a great series of “how to” videos on some of Emerson’s Rosemount brand of temperature measurement devices. This YouTube video series includes: How to Wire and Configure a Single Sensor for the Rosemount 648 Wireless Temperature Transmitter (runtime 3:19) How to Set Up a Dual Sensor for the Rosemount 3144P Temperature Transmitter (runtime...

    Wireless for High Temperature Electric Arc Furnace Control

    A key part of the Industrial Internet of Things is the sensors that provide the measurements that feed decisions and actions. At the Emerson Exchange conference in Austin, Emerson’s Cheng Vue presented, When the Heat is On, Control with Wireless. His abstract: Many measurement challenges exist when monitoring high temperature assets such as arc furnaces. These challenges include high temperature, moving platforms...

    Accurate Piping Surface Temperature Measurement

    We see the impact of the Internet of Things in our homes with devices like thermostats that we can control from our mobile devices. And we see it in industrial processes with the ever expanding variety of sensing devices to improve the safety, efficiency and reliability of these processes. One important area of innovation is being able to measure temperature without having to penetrate the piping or vessels with thermowells...

    High Pressure and Temperature Sensors for Subsurface and Surface Oil and Gas Applications

    In a Reuters article, Forget fracking. Choking, lifting latest efforts to stem U.S. shale bust , Andrew Slaughter, director for the Deloitte Center for Energy Solutions stated: Production optimization is going to be the next phase of the shale revolution… The low price environment will give companies and operators a chance to take stock of the techniques that work. One of the ways to optimize oil and gas production...

    Accurately Measure Process Temperature without a Thermowell or Process Penetration using Rosemount X-well Technology

    In an earlier post, Online Calculation Tool for Thermowell Installations , we shared ways to avoid resonant frequencies caused by fluid flow around a thermowell inside of process piping. But what if you could eliminate the need for the thermowell enti...

    Resources for Thermowell Selection and Design

    Measuring and controlling temperature can the most important parameter in many production processes. It’s not only the temperature sensors that are important, but how they are protected by thermowells. Wikipedia has a good definition of what thermowells are : Thermowells are tubular fittings used to protect temperature sensors installed in industrial processes. A thermowell consists of a tube closed at one...
