As the extreme conditions predominantly only prevail in the actual process, it makes sense to only design this area in the corresponding high-performance materials.

In many cases, the sometimes long path to the flange or threaded connection can be made from other materials. Different temperature zones and chemical-physical boundary conditions of the application areas make it necessary to use different, suitable materials. The actual design of the thermowell is determined by the individual conditions on site: immersion depth, medium, temperature, measuring principle, flow velocity, etc.
