10.3.3 Isolation Kit

The isolation kit (MI3100ISOKIT) can be used likewise for the fixed mounting bracket (XXXMI3100FB)
and the adjustable mounting bracket (XXXMI3100ADJB). Two non-conductive rings insulate the
sensing head (1M, 2M) electrically from the mounting bracket. The isolation kit is used to implement
installations with one earth grounded point only,voir paragraphe 4.5
page 22.
The maximal ambient temperature for the isolation kit is 250°C (482°F). The delivery for the isolation
kit consists of two insulating rings made of Teflon and a mounting nut made of stainless steel. The
desired mounting bracket needs to be ordered separately.
Make sure that the insulating rings are mounted so that both extruded lips facing each other. Use the
two mounting nuts to secure the arrangement.
Installing the Isolation Kit requires a mounting bracket in its latest version (inner
diameter of 20 mm (0.79 in) instead of 18.5 mm (0.73 in) for the previous version)!
