Temperature sensing device for rotatably moving parts and temperature detection method therefor

Described herein is a magnetic temperature sensing device for rotatably moving parts, of the type comprising at least a magnetic field source element (13) associated to said rotatably moving part (11) and a magnetic field sensing element (14) associated with a fixed part (15) to measure parameters of a magnetic field (H) determined by said magnetic field source element (13), said parameters of the magnetic field (H) being a function of the temperature (T) of said rotatably moving part (11). The magnetic field source element (13) comprises means (22) for rotating along at least an axis (25) the direction of said magnetic field (H) as a function of the temperature (T) of said rotatably moving part (11).
