Abstract:
PROBLEM TO BE SOLVED: To provide a temperature measuring device which accurately measures a temperature by using a radiation spectrum of a measurement object.SOLUTION: A temperature measuring device 20 has lighting means 3, extraction means 7, light intensity calculation means and temperature measurement means. The lighting means lights a radiation spectrum of a measurement object. The extraction means extracts light having a wavelength of an atomic beam spectrum and light having a wavelength within a wavelength region without atomic beam spectrum, from the radiation spectrum lit by the lighting means. The light intensity calculation means calculates the intensity of each light extracted by the extraction means. The temperature measurement means calculates a temperature of the measurement object on the basis of the intensity of each light calculated by the light intensity calculation means.
Abstract:
Devices and corresponding methods are provided to measure temperature and/or emissivity of a target. Emissivity of the target need not be known or assumed, and any temperature difference between a sensor and the target need not be zeroed or minimized. No particular bandpass filter is required. Devices can include one or two sensors viewing the same target as the target views different respective viewed temperatures. The respective viewed temperatures can be sensor temperatures, and a single sensor can be set to each of the respective viewed temperatures at different times. An analyzer determines the temperature and/or emissivity of the target based on the respective viewed temperatures and on plural net heat fluxes detected by the sensors and corresponding to the respective viewed temperatures.
Abstract:
Method for measuring the temperature of an object that is heated by means of one or more radiation sources, wherein radiation generated by the object is received in at least one radiation pick-up and wherein the radiation sources are changed at least partially in intensity at a predetermined cyclic rate of change and wherein on the basis of the change in the radiation value measured by the radiation pick-up the degree of compensation for the reflectivity and/or emissivity of the object is determined.
