Thermowells / protection tubes

For each measuring point requirement the optimum thermowell / protection tube

Thermowells / protection tubes from WIKA are used with demanding operating conditions both in solid-machined versions from bar stock material and in fabricated versions with tubular design. The variants offered differ mainly in their designs; with flanges, threaded or for welding in. The connection of the thermowells / protection tubes by flange is universal and is used in many processes. The compact form of the threaded connection saves space and mounting is also very easy. If the process safety and robustness is important, the thermowells / protection tubes can be welded into the process directly. 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 / protection tubes in accordance with global standards or to customer specifications ensure optimal protection for the sensor.
