The BriteSpot™ G3 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
fiber as a conduit for the optical signals which
are used for relaying the temperature data. The
materials exposed to energized components
are made of inherently insolating materials and
pose no risk to the equipment. Each BriteSpot
unit provides temperature information for
either nine or eighteen locations, which can
then be extracted in real-time via MODBUS
RS-485, MODBUS TCP/IP, or Ethernet I/P. In
addition, temperature values can be logged
internally and retrieved via standard CAT5
Ethernet cable.

The BriteSpot Fiber-Optic Temperature
Monitoring System consists of three major
components:
1. The G3 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 a 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.
