NOTICE
Powell is committed to continuous product
improvement.
It is possible that improvements occurred
between revisions to this document and
therefore, may not be described in these
instructions. If the equipment does not
resemble the photographs and descriptions
contained herein, contact Powell before
attempting to perform any actions.
The BriteSpot® Plus Fiber-Optic Temperature
Monitoring System is intended for use in
environments with high voltages and currents,
where standard measurement methods such
as RTDs, thermocouples, and IR scans are
not suitable. Point-source temperatures are
measured optically using a polymer optical
signals which are converted to temperature
data. The material exposed to energized
components are made of inherently insulating
materials and pose no risk to the equipment.
Each BriteSpot Plus unit provides temperature
information for either nine or eighteen
locations, which can then be viewed via the
display and/or extracted in real-time via
MODBUS R5-485, MODBUS TCP. In addition,
temperature values can be logged internally
and retrieved via an internal product web page.

The BriteSpot Fiber-Optic Temperature
Monitoring System consists of three major
components:
1. The BriteSpot Plus conversion module
provides the internal control signals,
interface telemetry and light
generation/detection that are needed to
interrogate the Location of Interest (LOI).
Each conversion module can measure
either nine or eighteen discrete points
when fiber-optic probes are attached.

2. The fiber-optic probe provides the optically
encoded temperature information from the
LOI to the conversion module. Composed
of polymer-based optical fiber and sensing
tip with locking feature, the probe is
designed to withstand voltages commonly
found in low and medium voltage
applications.
