TL;DR: In this article, the authors proposed a broadband composite magnetic sensor (BSMMS), which has a high frequency working mode and a low-frequency working mode, and the fluxgate sensor probe is fixed to a composite sensor structure at the middle position of the primary probe and the inductive magnetic sensor secondary probe, and is connected to a conditioning circuit through multi-core shielding cables.
Abstract: The invention relates to a broadband composite magnetic sensor. An inductive magnetic sensor primary probe and an inductive magnetic sensor secondary probe are installed at two ends. A fluxgate sensor probe is installed at the middle position of an inductive sensor hollow magnetic core. The inductive magnetic sensor primary probe, the inductive magnetic sensor secondary probe and the fluxgate sensor probe are fixed in a shell and are connected to a conditioning circuit through multi-core shielding cables. The broadband composite magnetic sensor has a high frequency working mode and a low frequency working mode, the fluxgate sensor probe is fixed to a composite magnetic sensor structure at the middle position of the inductive magnetic sensor primary probe and the inductive magnetic sensor secondary probe. Compared with a traditional single fluxgate sensor, the broadband composite magnetic sensor has the advantages that the sensitivity of a fluxgate sensor is improved, disadvantages that the high frequency noise of the single fluxgate sensor is high, the low frequency noise of a single inductive magnetic sensor is high, and a static magnetic field can not be measured are overcome, and the measurement of a wideband and low noise magnetic field is realized.

TL;DR: A non-contact inductive voltage divider (IVD) type displacement transducer that directly provides a digital output proportional to the displacement of the non- contact (floating) wiper is presented here.
Abstract: A non-contact inductive voltage divider (IVD) type displacement transducer that directly provides a digital output proportional to the displacement of the non-contact (floating) wiper is presented here. The floating wiper IVD becomes an integral part of a suitably modified dual slope type digital converter (DSDC) and the logic of conversion ensures that the digital output of the DSDC is not affected by the changes in the distance between the floating wiper and the inductive element. Simulation and emulation studies have been carried out to establish the feasibility and functionality of the proposed method. Experimentation on a prototype non-contact inductive angular displacement sensor built in the laboratory further corroborates the efficacy of the proffered technique.

TL;DR: An inductive sensor arrangement for detecting ferromagnetic or non-ferrous electrically conducting objects hidden in a surrounding medium comprising three field coils arranged in essentially the same geometric plane and adjacently positioned at angular distances of usually 120° from each other around a central axis orthogonal to the plane for generating an alternating magnetic flux by a sequential excitation with an AC-current ramp is presented in this article.
Abstract: An inductive sensor arrangement for detecting ferromagnetic or non-ferrous electrically conducting objects hidden in a surrounding medium comprising three field coils arranged in essentially the same geometric plane and adjacently positioned at angular distances of usually 120° from each other around a central axis orthogonal to the plane for generating an alternating magnetic flux by a sequential excitation with an AC-current ramp. The sensor arrangement further comprises three sense coils respectively mounted inside each associated field coil and in an orientation to the axes of each of the field coils such that essentially no voltage is induced in the sensor coils in an environment free of a metallic object. When a ferromagnetic or non-ferrous electrically conducting object approaches the sensor, nine characteristic voltage value sets are produced by the three sense coils which are stored and processed by an algorithmic process for defining a distinct criterion with respect to the position of the hidden metallic object to be located. The sensor arrangement uses a single point measurement to provide an accurate position and depth discrimination of the hidden ferromagnetic or non-ferrous electrically conducting object such as a rebar (R), a copper pipe in concrete or the like.
