optical pyrometer

[′äp·tə·kəl pī′räm·əd·ər]
(engineering)
An instrument which determines the temperature of a very hot surface from its incandescent brightness; the image of the surface is focused in the plane of an electrically heated wire, and current through the wire is adjusted until the wire blends into the image of the surface. Also known as disappearing filament pyrometer.

The MISS interface, with optical pyrometers placed along the cooling tunnel, receives identification data from castings on the molding line along with all the status signals of the Magaldi installation.
Bimetal thermometers and temperature-sensitive labels were followed later by machine-mounted optical pyrometers to display and, in some cases, to record surface temperatures throughout the process.
