device and method for measuring the distance of two points of a part, particularly for measuring the raddurchmessers a rail fahrzeugrades

摘要

The arrangement has a transmitter of electromagnetic radio waves and a receiver of a signal from at least one second point on the measurement object at which the waves are affected by the object that is proportional to the distance between the second point and a first or reference point. The contact point of the vehicle wheel on a defined rail part is defined as the first point and the second point is a defined rolling segment of the wheel. The arrangement has a transmitter of electromagnetic radio waves and a receiver of a signal from at least one second point on the measurement object at which the waves are affected by the object that is proportional to the distance between the second point and a first or reference point. The contact point of a peripheral segment (10) of the vehicle wheel (7) on a defined rail part (11) is defined as the first point and the second point is a defined rolling segment of the wheel. An independent claim is also included for the following: (a) a method of measuring the distance between two points of a measurement object, especially for measuring a rail vehicle's wheel diameter.
