Abstract

A metal detector includes oscillatory circuit, this comprises an inductive sensor, between the first and the second outputs of that one connected in series first and second capacitors are included, at that the input of the oscillatory circuit is the point of connection of the first and the second condensers and the second output of the inductive sensor, an the output of the oscillatory circuit is the first and the second outputs of the inductive sensor, and amplifier input of which is connected to the output of the oscillatory circuit, and the output is connected to the input of the amplitude detector output of which is connected to connected in series differentiation RC-circuit, threshold device and executive device. Additionally a controlled resistor and integrating RC-circuit is included. The first output of the controlled register is connected to the output of the amplifier, the second output of the controlled resistor is connected to the point of connection of the first and the second condensers, the control circuit of the controlled resistor is connected to the output of the integrating RC-circuit, and the input of the integrating RC-circuit is connected to the output of amplitude detector.
