Abstract
In a device for measuring the temperatures of axles and/or bearings to locate hot-boxes or overheated brakes in rolling stock, in which the infrared rays of the measuring points are directed onto an infrared receiver (8) via an oscillating mirror (9), whereby infrared rays emitted transversely to the longitudinal direction of the rails are detected in the scanning plane defined by the oscillation of the oscillating mirror (9), at least two deviation mirrors (1, 2) are arranged within the scanning plane at a distance (a) from one another transverse to the longitudinal direction of the rails. The deviated infrared rays of the deviation mirrors (1, 2) are detected in a chronological sequence in accordance with the oscillation of the oscillating mirror (9).
