Emerson Process Management’s thermowell calculator is now based on the new standard created by the American Society of Mechanical Engineers (ASME) that establishes the practical design considerations for thermowell installations.

Recently, ASME updated its standard on thermowells from the previous standard, created in 1974, to ASME PTC 19.3TW – 2010. The new standard is designed to help overall reliability of temperature measurement.

“The PTC 19.3 Committee collected feedback from end-users and manufacturers and considered experimental results from the last 30 years to bring the standard into the 21st century. The result is a comprehensive set of calculations that offer the designer a complete evaluation of the thermowell design for a set of process and installation conditions," says Dirk Bauschke, engineering manager for Rosemount temperature sensors and thermowells, who represented Emerson on the ASME committee.

As a service, Emerson, Chanhassen, Minn., provides recommendations on thermowell design and installation best practices that comply with the new standard. For more information, visit www.rosemount.com/thermowellcalculations.
