Abstract:
A device for measuring temperatures of parts of rolling stock on rails to locate hot-boxes or overheated parts of the rolling stock, comprisingan infrared receiver (8) for measuring infrared rays, onto which infrared rays emitted within measuring points (b, c) are directed; an oscillating mirror (9) arranged to direct the infrared rays onto the infrared receiver (8), so that infrared rays emitted transversely to the longitudinal direction of the rails (16) are detected by the infrared receiver (8) in a scanning plane defined by the oscillation of the oscillating mirror (9), and at least two deviation mirrors (1, 2) arranged within the scanning plane at a distance (a) from one another, transverse to the longitudinal direction of the rails (16), so as to direct the infrared rays to said oscillating mirror (9), allowing the infrared receiver (8) to detect the infrared rays in a chronological sequence in accordance with the oscillation of the oscillating mirror (9).
