Implicit uncertainties of temperature measurements during pyrometer calibration

https://doi.org/10.32446/0368-1025it.2018-11-68-72

Abstract

The previously unrecognized temperature measurement uncertainties that may occur during calibration of radiation thermometers (pyrometers) used for temperature measurements in the range of 1234,93-3273,15 K are considered. One of these uncertainties is shown to be related to the difference in spectral transfer functions of the interference filter of a calibrated pyrometer and a monochromator working temperature standard. Another uncertainty is due to the asymmetry of the spectral transfer function of the pyrometer relative to its central wavelength of the passband.
