Condition Monitoring
The Raytek® Equipment Monitoring System
is an early warning device that provides live
temperature data to operators, allowing them
to make educated decisions regarding the
functionality of their equipment. A temperature
rise or spike on the surface of equipment
can be a leading indicator that there may be
an equipment problem. Being aware of that
temperature change means system diagnostics
can be done and service planned with no
interruption to production - saving money in
time and resources.
The Raytek® Equipment Monitoring System
is a noncontact infrared monitor that provides
a 24/7 temperature measurement of actively
powered components or operating machinery.
Temperature is displayed on its LCD control
module and/or remotely through PC-based
Raytek DataTemp® Multidrop software.
The Raytek Equipment Monitoring System
is plug and play utilizing the field proven
technology of the Raytek Compact Series MI3
sensor. The system is small in size to fit in tight,
hard-to-reach or enclosed locations. The system
monitors temperature ranges of -40˚C to 600˚C
(-40˚F to 1112˚F) and all components are IP65
rated to ensure long life in harsh environments.
Users can manually program alarm settings
through the integrated push button panel
located on the control module or easily
communicate remotely from a central location
via RS-485 and DataTemp software. For full
factory or machine control, an ASCII Protocol
will allow the system to communicate with
your own internal control network.

The Raytek Equipment Monitoring System has been
developed with operator safety in mind. Offered with
3, 4, 6 or 8 sensors, temperatures can be read by anyone
on active systems from a safe location without additional
equipment or special training.
The DataTemp Multidrop software provides simultaneous
viewing of multiple points and can be set up to monitor up
to 32 systems. This provides the ability to see temperature
and set early warning alarms on a total of 256 individual
monitor points. Early alarms provide the time needed
for further investigation or maintenance by
qualified personnel.
Software features allow operators to easily
record and store data for trend analysis,
remotely make sensor parameter adjustments
or customize screen views. Additional
capabilities allow you to change the sensor
from reading object temperature to ambient
temperature, change emissivity, and turn on or
off filters to scale the range, graph or average.
