Because the system integrator may use any number of enclosure sizes, materials, thermal
solutions, and room conditions when designing an enclosure for a specific application,
NI sbRIO devices are specified in a manner that removes most of these external variables.
Therefore, the sbRIO-9637 thermal performance is not determined by measuring the external
ambient or internal/enclosure ambient temperatures, but by measuring the local ambient and
specific component temperatures. NI provides digitally reported temperatures to help you
accurately measure these critical temperatures.
Validating the System
NI recommends that you use a validation system for an extended period of time in a test
environment with the same thermal, environmental, and functional utilization characteristics as
the target deployment environment. You are responsible for final validation of your
application.
Validating Temperature Measurements Digitally
To meet the thermal specifications of the sbRIO-9637, you must satisfy the requirements of
either the digital or analog thermal validation approach as described in the
NI sbRIO-9637
Specifications
on
ni.com/manuals
. The sbRIO-9637 includes three onboard temperature-
monitoring sensors to simplify validation of a thermal solution. The sensors provide an
indication of thermal performance and are used to validate the system digitally.
