MWx-AS Aluminum Strip Pyrometer
Brand: Williamson CorporationMulti-wavelength pyrometers are used to measure the temperature of non-greybody materials. These are materials for which the emissivity not only varies, but varies differently at different wavelengths.
Traditional multi-wavelength pyrometers use static, application-specific algorithms to compensate for complex emissivity characteristics. The MW pyrometers assume that the surface conditions for these applications are relatively consistent.
The Williamson MWx pyrometer uses Dynamic ESP Technology to compensate for more significant variation in surface character and conditions without adjustments. For example, at the aluminum reversing hot rolling mill, the surface character of the aluminum varies dramatically from pass-to-pass, so the traditional MW technology is not appropriate.
