The COVID-19 pandemic took us all by surprise this year. It has affected everyone and every business. A very large portion of manufacturing was shut down in an effort to “flatten the curve,” and even those who remained open have dealt with COVID issues such as employees who are afraid to come to work for fear of being exposed.
Accurate temperature measurements are critical to forging processes and the metallurgical properties of forged components. For a given set of specific conditions, IR temperature sensors work reliably and produce repeatable temperature measurements – but not necessarily accurate ones. Accuracy comes from properly calibrating sensors to the specific materials and applications.
Part I of this article considered the technology of measuring temperature through the infrared radiation of a heated metal mass and some of the misconceptions and inaccuracies that may be present in or about the process. This article will explore ways to improve accuracy through proper calibration and to take temperature measurements of highly reflective bodies.
