Temperature measurements in industrial site inspections
The energy conservation activities, including the optimal
use of the primary and secondary energetical resources, represent the most
efficient steps to develop a healthy economy. To obtain this purpose, correct informations about
the energetical performances of the industrial equipments, outfits or complex
systems are needed. These informations are obtained by drawing up energetical
surveys or analysis on scientifical and technical grounds, based on the
acquired data in the industrial sites. The industrial equipments in which the technological
processes are imposing higher thermal levels (compared to the environment),
have energy losses which are dependent of the topology of the systems and
of the quality and conditions of the insulation. The evaluation of these energy losses, which cut
down the systems efficiency, implies the knowledge of the thermal distribution
for all the components of the equipments. This can be done with the thermovision
system, which visualises the temperature distribution on the surfaces of
equipments, by the remote recording of the IR-rays. The remote sensing
of temperature, has appeared as a military technology application in civilian
industry and science, after the fifties.
The thermography, a non-contact and a non-destructive
method, is useful for:
heat loss determinations in thermal instalations and similar.
defect tracing during the operation of mechanical, electrical or electronic
structural analysis of buildings.
Reported to other methods the thermography has a
number of advantages:
the inspection of the systems is performed, in an extremely economic way, without direct contact and without stopping the technological process.
the thermovision system furnishes an image, allowing a quick and precise
identification of the overheated points, representing potential defaults.
Also a primary evaluation of the heat loss is possible.
the recorded images can be interpreted with a dedicated program, on any
the early discovering of defects, the appreciation
of their risk degree, the timing of repairs is possible, obtaining this way
a decrease of the defect rate and a higher safety of systems.
