Paper Abstract

Temperature measuring on targets with low emissivity is difficult to take in the range of 0,1 - 0,2 by conventional methods and measuring equipment. In the temperature range below 200°C this type of measuring can not be carried out at all. Due to the low emissivity, the measuring result is to a large extend distorted by the ambient radiation reflected on the target. In addition to this, the emissivity is not exactly known in most cases and can change in the course of measuring. The innovative measurement system cited above is an answer to these difficulties. It is operated by 2 pyrometers of the same wavelength. Ambient conditions are defined for both pyrometers and measured as well. All signals are fed into a computer-aided interpretation system and are subsequently interconnected. The actual emissivity as well as the target temperature can be retrieved from this data.
