| 摘要 |
The invention relates to a metal detector with at least one driver circuit 2, at least one transmitter winding 4 having two external terminals 4a, b, and at least one receiver winding 5 having two external terminals 5a, b. The efficiency is increased in comparison to conventional metal detectors by providing at least one tap subdividing the transmitter winding 4, whereby a transformed electrical AC voltage is provided at the external terminals 4a, b of the transmitter winding 4 by the driver circuit via the tap 4c.
