ARRANGEMENT FOR MEASURING THE DISTANCE BETWEEN TWO SUCCESSIVE OBJECTS

摘要

An arrangement for measuring the distance between two successive track-carried objects which are equipped with a transmitter and a receiver. The transmitter of the forwardmost object transmits a signal which is received by the receiver of the next following object. The signal is transmitted over a line having a predefined signal attenuation factor so that the magnitude of the signal received by the receiver in the next following object is indicative of the distance to the forwardmost track-carried object. A single U-shaped core and windings associated therewith is utilized to transmit the signal into the line in the transmitter as well as receive the signal from the line in the receiver.
