Device for measurement of distance to current-conductive surface has body-screen with two inductivity coils placed in it, includes to circuit of support and measuring auto-generators, respectively, with outputs of those connected to inputs of frequency transformer, and input of frequency transformer through connected in series filters. Frequency detector and amplifier connected to input of measuring block, and adder, source of support voltage and current-conductive element installed before coil of support auto-generator. To the device are included elastic-inertial and viscoelastic elements, and current conductive element is installed with possibility of its displacement, besides that to the first input of adder device for signal averaging is connected, second input is connected to source of support signal. Output through control element is connected to second input of amplifier and forms back coupling. |
