2.2 Infrared Radiation Thermometers for G
ENERAL
A
PPLICATION
The Infrared Radiation Thermometers series KT19.81 II, KT19.82 II, KT19.83 II are
used to measure surface temperatures within a temperature range of - 50 to
1000 °C. The spectral sensitivity can be found within the range of the atmospheric
window, which is between 8 and 14 µm. As the atmospheric transmissivity is very
high in this spectral range, no weakening of the infrared radiation due to CO
2
or to
water vapor contained in the air is to be expected.
To meet especially high requirements as to the transmission of the atmosphere (as it
is a case e.g. when carrying out meteorological measurements) Infrared Radiation
Thermometer KT19.85 II is suitable.
The KT19.81 II, KT19.82 II, KT 19.83 II can be employed in the measuring of tem-
peratures during the production and processing of plastics, rubber, paper, textiles,
paint, ceramics etc. The emissivity of various metals is shown in figure 10
(Ch. 7: Figures).
The devices can also be used to measure the temperature of objects exposed to in-
frared radiation, since the radiation maximum of infrared radiators is within the range
of shorter wavelengths, which do not cause the Infrared Radiation Thermometers
KT 19.81 II, KT19.82 II, KT19.83 II to react.
The Infrared Radiation Thermometer KT19.81 II is used in the spectral range of 8 to
10
μm.
Besides being used for large-surface measurement, this Infrared Radiation
Thermometer type is also suitable for measuring thick foils.
The Infrared Radiation Thermometer KT19.82 II is applied for the standard measur-
ing range of 8 to 14 µm thereby guaranteeing a good signal resolution.
