Abstract
A device for measuring the rotation of a rotating element comprising an encoder element rotating with the rotating element and a sensor unit connected to a stationary element. A scraping element cooperates with a surface of the encoder element in order to eliminate contaminating particles present on the surface of the encoder element. The scraping element may be carried on the sensor device and may be biased against the encoder element by an elastic device or by magnetism.
