The most common probe mounting fixture for
use with the BriteSpot® Plus system is based on
industry standard ring-style cable termination
lugs. These lugs have proven to be reliable,
easy to install, and virtually maintenance free.
In addition, if installed at locations with existing
hardware, no modifications to hardware
lengths or specifications are needed. The fiber
probe has a special feature, called the “probe-
lock” which secures the probe to the lug
without crimping, allowing lugs to be installed
first, then the attachment of the probe.

1. Select the proper lug of the application
based on the existing hardware (if present)
or planned hardware. If purchased in kit
form, ½ inch lugs have been included.
Other sizes are also available as seen in
Figure 8 . When selecting the lug for a
given location, ensure that the lug with the
tightest fit around the hardware is selected
- this aids in proper thermal conduction and
will result in more accurate readings.

2. To make probe installation easier,
consideration must first be given to the
rotational orientation of the lug prior to
mounting. When the probe is eventually
installed, the fiber will need to have a
relatively unobstructed path to be inserted
into the lug. For example, in some situation
protective boots are placed over bolted
connections, posing an inconvenience
when routing the fiber. Align the fixture
to allow the fiber to be threaded through
existing seams in the dielectric boot. The
lug must also be placed such that the
“probe-lock” is accessible to an Allen key for
tightening.
3. Mount the lug so that it is directly
contacting the surface to be measured.
Washers should NOT be placed between
the lug and the surface to be measured;
instead they should be placed on the other
side of the lug, as shown in Figure 9 .
Figure 10 shows the proper installation
when Belleville washers are used.
Absolutely no greases and/or pastes should
be used between the lug and the surface
it is contacting. Ensure the orientation of
the lug is such that the probe and fiber run
parallel to the bus.
