Possible thermowell forms:
- Model TW20-A: tapered
- Model TW20-B: straight
- Model TW20-C: stepped
- "Quill Tip" version (with open tip)
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 TW20 series of solid-machined weld-in thermowells 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.
