25.4...49.5 mm - Temperature

Each thermowell is an essential component of any temperature measurement point. The WIKA TW25 thermowell 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 sensor 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 primary method of manufacture are critical design differentiation criteria. A necessary 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 barstock. The WIKA TW25 series of solid-machined thermowells with flange connection are suitable for use with numerous electrical and mechanical thermometers from WIKA. Due to the heavy-duty design, these international design thermowells are the first choice for use the chemical and petrochemical industries and in plant construction. This thermowell can also be ordered with the innovative ScrutonWell® design. The added helical shape on the outside of the insert increases the thermowell™s resistance to the Kármán vortex street and the stress this causes on the instrument by breaking the vortex up into smaller vortices. By incorporating the helix onto the outside of the thermowell, the Scrutonwell® design reduces oscillation by more than 90%!
