Back to overview
Each thermowell/protection tube 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 designs or materials of the thermowell/protection tube. 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/protection tube, and those with flange connections.
Furthermore, one can differentiate between protection tube and thermowells. Protection tubes are constructed from a tube, that is closed at the tip by a welded solid tip. Thermowells are manufactured from barstock.
The SWT52x series of threaded or weld-in protection tubes 1) are specifically adapted for use with model 52 mechanical thermometer.
Due to the cost-effective design and fast adjustment and exchange of the thermometer, these are the protection tubes of choice for use in machine building and heating technology.
