Zusammenfassung:PROBLEM TO BE SOLVED: To provide a radiation thermometer for enhancing measurement accuracy and measurement reliability by removing error factors depending on element performance of electronic circuit components or circuitry, and the effect of environmental temperature. SOLUTION: This radiation thermometer is equipped with an infrared sensor for outputting a sensor output signal corresponding to the amount of infrared rays radiated from a measuring object, a temperature sensor for outputting a sensor temperature signal corresponding to the temperature of the infrared sensor itself, an A/D converter for converting the output signal and the temperature signal into digital data, and a control part for calculating the temperature of the measuring object based on the digital data obtained by the A/D converter. At each prescribed time, the control part reads digital data into which the temperature signal is converted by the A/D converter. COPYRIGHT: (C)2005,JPO&NCIPI
