ABSTRACT:
The invention relates to a fiber optical temperature measuring device of the pyrometer type, comprising a transducer section and an electronic section, which are mutually interconnected by at least one optical fiber. The electronic section includes at least one light source and the light therefrom is arranged to be emitted via the optical fiber to the transducer, and in the transducer at least part of the light is reflected back into the fiber and is conducted through the optical fiber together with an output measuring signal from the transducer to one or more detectors included in the electronic section.
