Thermowell Calculation Service Now Based on ASME

Emerson's Thermowell Calculation Service is now based on the new standard created by the American Society of Mechanical Engineers (ASME). This 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 By using outdated standards to calculate thermowell size, there is an increased risk of failures due to increasing line sizes and pipe velocities.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 standard.

congatec Future-Proofs ETX and XTX Standard

Image
congatec AG, a leading manufacturer of embedded computer modules, is giving the ETX and XTX form factors a viable future with the integration of AMD Fusion technology. Modules based on AMD Fusion processors deliver significant improvements with regard to performance and scalability. Intel’s discontinuation of the 855 chipset family left a major gap in the market particularly for ETX computer modules, which primarily affected the higher performance range of applications. This gap has now been closed by processor manufacturer AMD with the Fusion architecture. Fusion also opens up new perspectives for a wide range of innovative and graphics-oriented applications.congatec has integrated the AMD Fusion architecture into its product range of ETX and XTX COM modules, opening up new scalability options for this form factor to meet even the most demanding tasks. The company supports the Fusion architecture with two new COM modules: conga-EAF and conga-XAF. While conga-EAF is an ETX module, co...

Haydon Kerk Motion Solutions Releases 36mm Linear Actuator Configuration that Replaces Existing 42mm Packages

Image
Haydon Kerk Motion Solutions, a premier manufacturer of linear motion products, has released a new version of its popular 36mm G4 linear actuator. This new configuration includes a special adapter plate that allows the smaller 36mm OD unit to replace 42mm and 46mm units in existing applications. Performance of the 36mm G4 linear actuator not only exceeds the performance of comparable size actuators, it approaches the performance of larger 42mm and 46mm linear actuators from various manufacturers. The 36mm unit with the integrated adapter plate allows users to replace existing 42 and 46mm units easily by using the same bolt pattern and pilot surface. Among the advantages of substituting the 36mm G4 linear actuator include a smaller linear actuator body, which is especially important when space is a premium, and a lower cost system, compared with the larger-size units. With the G4 linear actuator, both can be accomplished without sacrificing performance or lifespan. Force output rang...
