A new measuring technique has been developed to show more clearly where there is a risk of cage-guide equipment getting stuck or moving out of the guides. Mechanical path changes are no longer registered via Bowden wires, but as electrical signals by inductive displacement transducers on magnetic tape storage. For monitoring purposes the deviation of the gauge and of the guide width from the specified values are recorded as an analog document in diagram form. Special calibrating, filtering and support measures used in the offline analysis enhance the measuring accuracy by several orders of magnitude, which is why this method is suitable for indicating where line location measures are required. The application of the principles of inertial navigation to measuring the path travelled is superior to the roller-feeler system and a simplified version could be used for routine control measurements. Some promising preliminary tests have already been conducted with this in mind.
