Two-Colour Pyrometers

Toshniwal Sensors offers Two-Colour Pyrometers, Metis MQ11 and MQ22. Two-colour or ratio- pyrometers are pyrometers, which measure temperatures from the ratio of radiation signals of two adjacent wavelengths as compared to measuring the absolute intensity like single wavelength units do. The advantages for customers are the following: gray bodies, i.e., targets with the same emissivity on both wavelengths, can be measured without emissivity setting. There is automatic compensation for dust, smoke or a dirty viewing window between pyrometer and target. Temperature errors are minimised if the target is too small or moving and the field of measurement can"t be completely covered. Metis two-colour pyrometers have universal applications, which means that they can also be used as two-colour pyrometers as well as single wavelength pyrometers. In single wavelength mode, customers have the choice of deriving the analogue output signal from shorter or longer wavelengths, or both. Using digital communication these temperature measurement results can be recorded and compared, to determine quickly whether the target is a "gray body" radiator or not. These are most suitable for burning zone temperature measurement of rotary cement kiln and for molten glass temperature measurement.
