Fibre optic cable pyrometer

In a fibre optic cable pyrometer, the lenses and electronics are physically separated. A fibre optic cable transmits the infrared radiation from the measuring head to the electronics. The spatial separation distinguishes fibre optic cable pyrometers from compact pyrometers.

The measuring head can be used without cooling in high ambient temperatures, electromagnetic fields or in confined spaces. A laser pilot light is used as a sighting device.
