ABSTRACT:
The present invention constitutes a pyrometer device and an associated method of operation for measuring temperature based on the radiation emitted by a heated body in which increased accuracy is achieved by actively ascertaining the emittance of the body whose temperature is being measured. The pyrometer device includes a light source for intermittently illuminating the heated body and a radiation sensing mechanism for measuring the amount of light reflected and radiated by the body. The pyrometer device further includes a signal processing unit for processing the information developed by the radiation sensing mechanism and deriving the temperature of the body based on a calculated emittance factor and the amount of light radiated by the body.
