Hint: inductive coupling to cables laid in the earth

02.02.06

The simplest and quickest way to couple the location signal to cables laid in the soil is the inductive method. Here you can read how it works and how to avoid mismeasurements

For the inductive coupling method the transmitter is simply put on the ground and, via an integrated coil, transmits the selected location frequency into the soil. This function is available for all SebaKMT transmitters up to 50 Watts transmission power.

The “broadcast” location frequency can now be located using a receiver on the cable. Here, care must be taken that, depending on the transmission power, a minimum distance to the transmitter is maintained. Otherwise the signal may be received directly from the transmitter and not from the cable, which you are trying to trace.

To check whether the signal is coming from the transmitter or from the cable, it is sufficient to simply lift the receiver from its location.
If the received signal strength gets weaker, then you are detecting the signal from the cable.

If the signal gets stronger or stays constant, then you are receiving the signal directly from the transmitter. Should this be the case, either reduce the output power or move further away from the transmitter.
