Infrared thermometer CellaTEMP® PK / PKF / PKL Temperature is determined using the ratio method by simultaneously measuring the thermal radiation emitted by soot particles at two wavelengths. A dedicated evaluation algorithm compensates for wavelength-dependent radiation characteristics of the soot particles as well as variations in optical flame density. Continuous monitoring of flame temperature provides valuable information about the combustion process. Based on this information, pollutant emissions can be reduced and slag formation on combustion chamber walls minimised. This contributes to...

Infrared thermometer CellaTEMP® PK / PKF / PKL Optical System An infrared thermometer is an optical measuring instrument for non-contact temperature measurement. The quality of the optical assembly has a significant influence on measurement accuracy. One of the most important factors is the so-called Size of Source Effect (SSE). Stray radiation entering the detector from outside the actual measuring field can cause measurement deviations. Especially with varying measuring distances or different object sizes, this effect may lead to changes in the measured value when using simple optical systems....

received infrared radiation and detects deterioration of the measurement signal at an early stage. If contamination of the optics, protective window or deposits in the furnace opening reduce the signal strength below a critical level, this condition is automatically detected and indicated directly on the instrument. In addition, the status can be transmitted to the control system via a switching output or the communication interface. The sensitivity of the monitoring function can be adapted to the specific process conditions. Continuous condition monitoring supports predictive maintenance and...
