Surface Temperature Measurement of Plastic films with Thermal Imaging Camera

Radiometric infrared thermal imaging cameras with specially adjusted wavelengths are used for hand-held sampling purposes as well as for permanent installed “in-line” measurements.

Correct surface temperature measurements in the infrared spectrum of transparent materials such as plastic film, preferably would be taken at:

 

Wavelength of 3.43µm with a spectral window of approx. 100nm bandwidth.

Under usage of concerted Infrared filters measured temperature deviations, arising from the background of any diaphanous objects, over the entire wavelength range of a conventional thermal imaging camera, can be herewith extensively avoided.

For reliable temperature measurements specific material parameters such as emissivity, temperature level and reflecting temperature have to be considered [TBC e.g. TRef) even the atmospheric compensation model [TAir (°C), Humidity (%), Distance (m)].

Surface Temperature Measurement of flames with Thermal Imaging Camera

Radiometric infrared thermal imaging cameras with specially adjusted wavelengths are used for hand-held sampling purposes as well as for permanent installed “in-line” measurements.

Correct surface temperature measurements in the infrared spectrum of transparent materials such as flames, preferably would be taken at:

Wavelength of 4.5µm with a spectral window of
approx. +/-100nm bandwidth.

Under usage of concerted Infrared filters measured temperature deviations, arising from the background of any diaphanous objects, over the entire wavelength range of a conventional thermal imaging camera, can be herewith extensively avoided.
