3 Intended use

The thermowell protects temperature sensors against aggressive media, high pressures and high flow velocities.

The Thermowell allows replacement of the sensor without process interruption.

4 Installation

General notes on the welding operation:

▶ The welding operation is to be carried out by qualified personnel according to state-of-the-art technology.
▶ Use materials and welding operations that are suitable for the housing material.
▶ Keep the surfaces free from any contamination.
▶ Ensure the careful preparation of the components.

In case welded adapters are used, the food contact surface must be smooth (surface roughness Ra < 0.8 μm) and the welding has to be done according to EHEDG Guideline 9 and 35.

Welding operation:

Fig. 1: Applying the fixing points

Fig. 2: Applying the welding seams

▶ Apply the fixing points of the welding thermowell at equal distance (crosswise) with a sufficient adhesive force.
▶ Apply the welding seams between the fixing points opposite each other.
▶ Ensure sufficient intervals between the individual welding operations to avoid glowing through or warping of the welding thermowell due to overheating.

After completion of the welding operation:

▶ Let the workpiece cool down.
▶ Slightly grease the thread using a lubricating paste which is suitable and approved for the application.
▶ Screw the sensor into the adapter and tighten. Tightening torque: 30...50 Nm.
