Further development of the PYROINC NIR thermal imaging cameras for applications in combustion chambers

The robust thermal imaging cameras of the PYROINC series from DIAS Infrared allow non-contact temperature measurements in combustion chambers. The cameras have long borescope or endoscope optics that are housed in a water- or air-cooled stainless steel probe cooling jacket. The probe cooling jacket is inserted directly into the combustion chamber through an opening. The small entrance opening of the optics is air-purged and has a protective window. An automatic retraction device ensures maximum safety of the entire system. The front part of the probe cooling jacket with radiation entry opening enables temperatures of up to 1800 °C with a service life of 2 to 10 years (strongly dependent on the specific operating conditions).

New measuring temperature range starting from 650 °C

PYROINC thermal imaging cameras work in different wavelength ranges depending on the application. In the near infrared range (NIR) there are now the further developed HD camera types PYROINC 1600N (1600 x 1200 pixels) and 1920N (1920 x 1080 pixels) with measuring temperature ranges between 650 °C and 1800 °C (spectral range 0.8 µm to 0.9 µm) available. The devices have endoscope optics with a probe diameter of just 60.3 mm. Example applications include non-contact temperature measurements in glass melting furnaces or when hardening and tempering steel in walking beam furnaces.

More application areas available

The PYROINC thermal imaging cameras are also available in other spectral ranges. The spectral range around 3.9 µm is suitable for measurements through flames. 3.9 µm cameras are used, for example, to detect unacceptable slag formation in combustion chambers in power plants or for burner control. Camera systems in the wavelength range around 10.6 µm are used, among other things, to monitor the condition of aluminum and zinc recycling
