What is Emissivity? Not all surfaces are the same. Depending on what you’re pointing your infrared temperature sensor at you’re likely to get variations in emitted infrared energy. This variation is called emissivity. Emissivity is a measure of a material’s ability to...

Editor’s Note: This blog post was originally published in 2015 and has been updated for accuracy and relevance. In the world of infrared temperature sensors, there are two types ofratio pyrometers: Two-Color (TC) and Dual-Wavelength (DW). Both use a ratio of... by Kam Olaogun | May 30, 2019 | Pyrometer, Wavelength
Infrared pyrometers are excellent devices to use when a direct contact measurement may not be possible. Often times the things we are trying to measure are simply too hot for contact devices like thermocouples or resistance thermometers. In addition, the things we are...

Hot Slug Detector: Hot slugs form when a process upset causes molten glass to fall from the spinner and into the product during the manufacturing of fiberglass batting. Surrounded by insulating material, these hot slugs remain hot, and days later can cause the paper...

Williamson Short-Wavelength Advantage Infrared pyrometers rely on making a reading based on the amount of energy collected. The amount of energy collected can be affected by emissivity variance and optical obstructions. Selecting the shortest possible wavelength helps...

Not all annealing lines have the same accuracy requirements. Some alloys require tighter temperature control than others. Plants that run high-strength steel or dual/complex-phase steel require precise control of steel temperature. Plants that run low-alloy steels for...
