Tim worked with the Rosemount thermowell technologists on a Thermowell Design Accelerator tool to ensure engineers get a reliable, accurate and safe temperature measurement for its intended application.
Unlike pressure and flow measurement, temperature measurement can be much more complex given what is being measured. Fluids have thermal inertia characteristics which determine their temperature rate of change. In a Process Heating article, Instrumentation Solves...
A great source for fundamentals in process automation is the International Society of Automation (ISA)'s InTech Focus electronic periodical. This series of electronic magazines: …focuses on the fundamentals of essential automation components, such as instrumentation,...
When it comes to measuring temperature, there are a multitude of ways to do this. Do-it-yourselfers might use simple RTD or thermocouple sensors right into a microcontroller and display to provide basic temperature readings for their grills and BBQ pits. Or they could...
Emerson's Jeff Williams presented, Holistic Approach to Steam Temperature Control, at the 2018 Ovation Users' Group Conference. Jeff opened describing the trend of plants being started and operated more frequently than in the past due to intermittent sources of...
As the contribution of renewable energy sources grow on electrical power grids, so does the cycling its intermittency creates for power producers. This cycling affects steam used to drive the generators. For power stations where the electric generators are...
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...
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,...
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...
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...
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...
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...
