Abstract

A measuring device may be used to measure a position of at least one current collector arranged in an articulated manner on a current collector trolley of a current collector unit relative to the current collector trolley. The measuring device may include at least one sensor unit having at least one sensor and may be arranged on the current collector trolley. A permanent magnet may be arranged on at least one of the current collectors The at least one sensor may be a Hall sensor whose sensor signal may be used in determining a position of at least one of the current collectors, which may be fitted with permanent magnets.

Claims29

Dependent claims

A measuring device for measuring a position of at least one current collector arranged in an jointed manner on a current collector trolley of a current collector unit relative to the current collector trolley, the measuring device including:

at least one sensor unit which has at least one sensor and is arranged on the current collector trolley,
wherein at least one permanent magnet is arranged on at least one of the at least one current collector, and wherein at least one of the at least one sensor is a Hall sensor,
wherein the measuring device is enabled to derive the position of a respective one of the at least one current collector having a respective one of the at least one permanent magnet based on at least one sensor signal of the at least one Hall sensor.

Dependencies are inferred from the claim text.
