Metrological Assurance of Thermal NDT Instruments: Measuring Thermal Imagers and Pyrometers
The validity of the results depends on matching the parameters of NDT to the application tasks. In accordance with the current normative-technical documentation for metrological assurance of thermal imagers and pyrometers standards of unit of temperature - blackbody emitters are applied. Transfering scheme of the unit of temperature is described. A description of the main operations carried out in the verification or calibration of thermal imagers and pyrometers is shown.
At the moment system of metrological assurance of thermal imagers and pyrometers that includes the normative documentation on methods of verification (calibration) and a set of metrological equipment is developed.
Keywords: temperature, standard, state primary standard, blackbody, thermal imager, pyrometer, radiation thermometer.
