    Description
     Each thermowell is an important component of any temperature measurement 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 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 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
barstock.
     The TW10 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.
