Probing Inductive Hypersensitive Installation

The paper is concerned with a dual-channel inductive installation for remote probing based on a new design principle. The operation of each measuring channel is based on the implementation of various physical principles thus providing linear independence of their static transformation functions. The signal from the first measuring channel controls the operating modes of the second measuring channel, and due to this, the ferrite magnetic antenna switches to the magnetic amplifier operating mode. Making use of the resonant excitation mode of a frame antenna improves significantly the sensitivity of the inductive installation. Performance features of measuring channels were investigated. The structure flowchart of the inductive installation is also presented in the paper.
