How Multi-Wavelength Pyrometers Work
Multi-wavelength pyrometers use application specific algorithms to characterize infrared energy and emissivity across the measured wavelengths to accurately calculate both the actual temperature and emissivity of these complex non-greybody materials. These algorithms have been developed and refined from extensive data collected from off-line simulations and on-line trials. Each multi-wavelength sensor can hold up to eight selectable algorithms, so that the same pyrometer can be used for multiple applications.
