4.1MeasurementofInfraredTemperature
All surfaces emit infrared radiation The intensity of this infrared
radiation changes according to the temperature of the object.
Depending on the material and surface properties, the emitted
radiationliesinawavelengthspectrumofapproximately1to20μm.
Theintensityoftheinfraredradiation(”heatradiation”)isdependent
on
the material. For many substances this materialdependent
constant is known. This constant is referred to as the ”emissivity
value”.
Infrared
Basics
4.2EmissivityofTargetObject
Todeterminetheemissivityof thetarget objectrefertosection12.1
Determination of Emissivity on page 80. If emissivity is low,
measured results could be falsified by interferinginfraredradiation
from background objects (such as heating systems, flames, firec lay
bricks, etc. close beside or behind the target object). This type of
problemcanoccurwhenmeasuringreflectivesurfacesandverythin
materialssuchas
plasticfilmsandglass.
Thismeasurement error can be reduced to a minimum if particular
care is taken during installation, and the sensing head is shielded
fromthesereflectingradiationsources.
4.3AmbientTemperature
The sensing head was developed for the following ambient
temperatureranges:
MIH:0to180°C(32to356°F)
MIC: 0to125°C(32to257°F)
MID:0to85°C(32to185°F)
The MID can operate in ambient temperatures up to 200°C (392°F)
withtheaircoolingaccessory.
4.4AtmosphericQuality
If the lens gets dirty, infrared energy will be blocked and the
instrumentwillnotmeasureaccurately.Itisgoodpracticetoalways
keep the lens clean. The Air Purge Jacket helps keep contaminants
from building up on the lens. If you use air purging, make sure a
filtered air supply
with clean dry air at the correct air pressure is
installedbeforeproceedingwiththesensorinstallation.
