Description
Each thermowell/protection tube 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 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/protection tube 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/protection tubes, and those with flange connections.
Special features
- Heavy-duty design
- Coating for corrosive or abrasive process loads
- Possible thermowell forms: tapered, straight, stepped

| Wake frequency calculation (option) | The calculation in accordance with ASME PTC 19.3 TW-2016 of individual thermowells minimises the risk of dynamic damage that can be caused by the vortex shedding of a Kármán vortex street (Vortex Induced Vibration; VIV). In addition, the static loads due to lateral flow and the process pressure are calculated depending on the temperature. The calculation can be carried out independently using an online tool or as aWIKA engineered service (subject to charges). → |
