Abstract RU 2180447 C2

FIELD: search for current-conducting objects, specifically, electric cables and pipe-lines. SUBSTANCE: device incorporates differential variable-induction pickups connected to input of operational amplifier, detector, electric-to-acoustic signal converter, balance resistors and voltage-to-frequency converter. Outputs of differential pickups are connected via balance resistors to inverting input of operational amplifier which output is connected to input of voltage-to-frequency converter via voltage amplifier and detector connected in series. Output of voltage-to-frequency converter is loaded to converter. EFFECT: raised functional efficiency of device. 1 dwg
