WIKA

Thermowells

For each measuring point requirement the optimum thermowell

Thermowells from WIKA are used with demanding operating conditions both in solid-machined versions from solid-body material and in fabricated versions with tubular design. The variants offered differ mainly in their designs; with flanges, with threads for screwing in or for welding in. Furthermore, all connections for sanitary applications and also thermowells in solid-machined Vanstone design are available without weld seams. The selection of materials and the manufacturing of the thermowells in accordance with global standards or to customer specifications ensure optimal protection for the sensor.

FAQ

What are suitable materials for thermowells for negative temperatures?

The first choice for high-temperature applications should always be stainless steel, such as 1.4404 or 316L. (Approval per AD2000 W10 down to -270 °C) Carbon steels should be considered carefully in detail, through the effect of the drop-off effect. More ...

Are there different ScrutonWell® designs for gaseous and liquid media required?

No, the design of the ScrutonWell® can be used in gaseous and liquid media. The WIKA -ScrutonWell® design is based on the ASME paper “Helical strakes in suppressing vortex-induced vibrations” (ASME report 11/2011 vol. 113.). The tests for this report ... More ...

How high is the permissible pressure loading for thermowells?

In the Appendix to DIN 43772 are loading diagrams, from which, depending on temperature and medium, can be taken, the maximum allowable pressure load for the different geometries. If the conduit geometry does not correspond to DIN 43772, individual c ... More ...
