Aluminum Pyrometers for Extrusion, Casting, Rolling, Forging

Aluminum Pyrometers are Infrared thermometers that measure the amount of infrared energy emitted by an object’s surface and convert this signal into a temperature value. While many factors affect the measurement accuracy, the most important consideration is selecting the sensor design that most effectively compensates for the emissivity characteristics of the measured surface.
Successful temperature measurement of ‘non-grey body’ materials, such as aluminum, requires using a multi-wavelength sensor to compensate for the complex emissivity characteristics of these materials. For example, aluminum emissivity variations occur with changes in the alloy, surface oxidation, surface texture, surface contamination, and crystal structure.
