Abstract

A mechanism of a monitoring unit of an electric rotating machinery covered in a housing that intercepts photoelectron transmission, the mechanism has: a monitoring window penetrating a part of the housing and configured to allow passage of photoelectrons and not to allow passage of gas; a camera arranged outside the monitoring window and configured to receive radiated photoelectron generated in the housing and passing through the monitoring window and to generate image data from the radiated photoelectron; and a computing unit configured to process the image data. The computing unit has reference image data storage means for storing image data resulting from blackbody radiation occurring in a reference state in the housing, as reference image data, and temperature calculating means for comparing the image data with the reference image data, thereby to calculate the temperature in the housing.
