Device for Measuring the Temperature of the Overheating of the Revolving Parts of Machines

摘要

In measuring the temperature of overheating of the revolving parts of machines, for example, the disk armatures of electrical machines, with the aid of photoelectric pyrometers, it is impossible to keep out error connected with the turning of the part. The proposed device makes it possible to decrease this error. It contains an ordinary photoelectric pyrometer with a revolving cut-off and is distinguished from the known devices for the same purpose by the fact that, for improving the precision of the measurement by means of a stroboscope effect, the cut-off is provided with a drive which assures its turning synchronously with the revolving part.
