2. Safety ... 5. Transport, packaging and storage
WARNING!
Thermowells are designed and calculated using ASME PTC 19.3 TW-2016 for
use in steady (laminar) flow conditions. Pulsating (close to the discharge of a
pump), turbulent flows (close to a piping fitting) or conditions outside steady flow
should be considered/evaluated during the design of a thermowell by the end
user.

3. Specifications

For specifications see the appropriate WIKA data sheets for current thermowell versions
and the order documentation.

4. Design and function

4.1 Description
Metal thermowells can be manufactured as solid-machined or fabricated versions. Thermo-
wells can be connected to the process by screw-, weld- or flange-fitting. The temperature
sensor is directly fastened to the thermowell using a female or male thread or by means of
an neck tube.
If thermowells made of metallic materials do not show a sufficient temperature or corrosion
resistance during continuous operation at temperatures above 1,200 °C, ceramic thermo-
wells should be used.

4.2 Scope of delivery

Cross-check scope of delivery with delivery note.

5. Transport, packaging and storage

5.1 Transport
Check thermowell for any damage that may have been caused by transport. Obvious
damage must be reported immediately.
5.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, sending for repair).
