SignalSelect is a patent technique for identifying the direction of signal flow in a line. This technique clearly enhances the reliability and efficiency of route position finding.
It has its particular merits in all events where there are a number of systems on the site running closely side by side.
The generator system FLG 10 generates an especially modulated audio frequency signal which is transmitted into the line either directly or inductively. The receiver system FLE 10 / FS 10 detects this signal over the target line and determines the direction of the signal flow (In detail >>>).
