Process Thermal Imaging in the Modern Hot-Rolling Mill ...

 · Noncontact pyrometers outlast contact sensors. They have very fast response speeds and are low maintenance. For some applications, a single-point pyrometer provides enough information for process control. In a hot-strip mill, a single-point pyrometer will measure a stripe (longitudinal profile) along the strip centerline.
