PYROMETER Russian patent published in 2004 - IPC

FIELD: information-measurement and computation hardware. SUBSTANCE: pyrometer has inlet made of substance clear in range of utilized wave lengths of thermal radiation, two photoelectric sensors of radiation intensity with selection on various wave lengths, two analog-to-digital converters, comparator, three OR gates, AND gate, five groups of AND gates, master unit of proportionality factor, two arithmetic units and former of leading edge of pulse. Technical result of invention lies in that given pyrometer secures measurement of temperature of surface of heated bodies in wide temperature interval with varying angle of sight and distances of radiation detectors from radiation sources, exclusion of reference radiation source. EFFECT: raised operational accuracy and reliability, reduced operational expenses. 1 dwg
