June 2, 2011 - Emerson Process Management’s Thermowell Calculation Service is now based on the new standard created by American Society of Mechanical Engineers (ASME) that establishes the practical design considerations for thermowell installations.  With the help of Emerson and other users, ASME updated its standard on thermowells from the previous standard created in 1974, to create the ASME PTC 19.3TW – 2010.  The new standard is designed to help overall reliability of temperature measurement.   Using this new standard, a specially trained Emerson team provides recommendations on thermowell design and installation best practices.  Calculations done by Emerson, following the ASME PTC 19.3TW - 2010, provide the most up to date, accurate, and complete thermowell recommendations. Rosemount thermowells are built with industry-standard ASME materials to provide users with safer, more reliable sensors for applications where a thermowell is needed.  All Rosemount thermowells are manufactured with these properties to ensure consistency between the thermowell calculation and the thermowell that is installed in the application. By using outdated standards to calculate thermowells size, there is an increased risk of failures due to increasing line sizes and pipe velocities.  Emerson provides engineering assistance to avoid these failures by using the new ASME PTC 19.3TW – 2010. “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.  Combine this with our world-class Thermowell Calculation Service and you have a calculation report you can rely on,” said Dirk Bauschke, engineering manager for Rosemount temperature sensors and thermowells, who represented Emerson on creating the new ASME standard. For over 50 years, Emerson’s Rosemount temperature portfolio has provided reliable temperature measurement to the process industry.  About Emerson Process Management Emerson Process Management, an Emerson business, is a leader in helping businesses automate their production, processing and distribution in the chemical, oil and gas, refining, pulp and paper, power, water and wastewater treatment, mining and metals, food and beverage, life sciences and other industries.
