LumaSense Technologies LumaSHIELD Controller Installation Guide: Winding Temp. Sensors - Manual (Page 3)

The customer must prepare its own key spacers for install-
ing the fiber optic sensor. A groove and an opening have
to be made in the spacer. The fiber optic temperature sensors provided by
LumaSense can be ordered with a mounting disc. This disc,
mounted of the sensor fiber-optic cable, is inserted into
the round opening of the grooved key spacer as shown
on Figure 10. Since the disc is held tight into the opening,
there is no need for using adhesive.
The disk is 2 mm thick, so the minimum spacer thickness
must also be 2 mm.
The following figures show the assembly procedures of
the fiber optic sensor into the grooved key spacer.
