5.4 PROCEDURE FOR INSTALLATION WITH ADHESIVE – GENERAL GUIDELINES
The sensor can be fixed with adhesive as an alternative to the standard screw mounting, that is, in cases
where fixing the sensor to a surface is not possible by drilling it. WEG suggests the 3M two-component
epoxy adhesive DP8407NS or similar product, checking if the maximum service temperature of the adhesive
withstands the maximum temperature of the application surface. This fixation method can be made:
Directly: applying the adhesive in the area of the metallic bushing at the base of the sensor, as shown in
Figure 5.3. The amount of adhesive applied must be enough to cover the entire area of the bushing.

By Intermediate Support: The mounting with intermediate support provides a robust installation with
relative flexibility, as the sensor is fixed with a screw on the support. For installation, it is recommended
to use a 12 mm high base, as shown in Figure 5.4c, and M4 x 40 mm stainless steel screw. There are
no restrictions on the diameter of the support, but it is recommended that the base be in contact with
the entire sensor bushing area. WEG recommends stainless steel or aluminum bases to avoid oxidation
problems. There is no restriction on the use of other materials, as long as their ability to withstand the
environment is considered.
