Each thermowell is an important component of any temperature measuring point. It is used to separate the process from the surrounding area, thus protecting the environment and operating personnel and keeps aggressive media, high pressures and flow rates from the temperature probe itself and thereby enables the thermometer to be exchanged during operation.
Based on the almost limitless application possibilities, there are a large number of variants, such as thermowell designs or materials. The type of process connection and the basic method of manufacture are important design differentiation criteria. A basic differentiation can be made between threaded and weld-in thermowells, and those with flange connections.
Furthermore, one can differentiate between fabricated and solid-machined thermowells. Fabricated thermowells are constructed from a tube, that is closed at the tip by a welded solid tip. Solid-machined thermowells are manufactured from bar stock or from forged blanks.
The TW31 series of solid-machined thermowells for lap flanges are suitable for use with numerous electrical and mechanical thermometers from WIKA.
Due to the exceptionally heavy-duty design, these thermowells in accordance with Shell design are the first choice for use in the petrochemical and also the oil and gas industries.
