TL;DR: In this paper, it designs a measuring system of bearing thickness which is based on the four elements of the measuring system, using v-shaped blocks to achieve high-precision semi-automatic positioning of the bearing.
Abstract: In this paper, it designs a measuring system of bearing thickness which is based on the four elements of the measuring system. It's using v-shaped blocks to achieve high-precision semi-automatic positioning of the bearing. It is using differential inductive sensor for measurement, the signal has processed by AD698 firstly, then through analog-to-digital conversion, the signal input into SCM, SCM control the system, after calculating the input signal, LCD displays the measurement results, and measurement data will be stored by the USB protocol to USB flash disk at the same time. This bearing thickness detection system has high degree of accuracy, low cost and suited to workshop casual inspection.

TL;DR: In this paper, the authors proposed a miniature inductive proximity sensor consisting of a coil combination, an iron core made of soft-magnetic material, and lead wires, and the coil combination is inserted into the central column of the iron core, and input and output lead wires of the coil are led out through the lead wire outgoing hoes.
Abstract: The utility model provides a miniature inductive proximity sensor. The proximity sensor comprises a coil combination (1), an iron core (2) made of soft-magnetic material, and lead wires (3) On the disc-shaped geometric body of the iron core (2), characteristic adjusting holes (4) for adjusting the size of the inductance are symmetrically formed on two sides of a central column of the iron core, and lead wire outgoing hoes (5) are formed far away from the central column of the iron core, being perpendicular to the connection line of the centers of the characteristic adjusting holes (4). The coil combination is inserted into the central column of the iron core, and input and output lead wires of the coil are led out through the lead wire outgoing hoes (5). According to the utility model, the coil combination with the lead wires is formed after insulating binding, and the lead wires are firm and reliable, so that the proximity sensor is small in size and light in weight; and the proximity sensor only has two mechanical processed components, being extraordinarily simple in structure.

TL;DR: In this paper, an inductive sensor assembly including a sensor assembly and a shaft was provided. But the inductive coupling between the transmitter coil and the two-part receiver coil was not discussed.
Abstract: In accordance with one embodiment of the present disclosure, an inductive sensor assembly is provided. The inductive sensor assembly includes a sensor assembly and a shaft. The sensor assembly include a transmitter coil and a two-part receiver coil. The shaft includes a first end. The first end includes a first planar surface and a second planar surface. The second planer surface extends from the first planar surface. A target is formed from the first planar surface and the second planar surface. When the target is moved about a shaft axis, the first planar and second planar surfaces modify an inductive coupling between the transmitter coil and the two-part receiver coil.

TL;DR: In this paper, a sine wave oscillator for an inductive sensor system is described, where the decoupler is configured to provide a pulse width modulated signal with a predetermined frequency and a predetermined duty cycle at one pin of the microcontroller.
Abstract: A sine wave oscillator for an inductive sensor system is disclosed. The sine wave oscillator comprises a decoupler and a low-pass filter, wherein the decoupler is configured to provide a pulse width modulated signal as a decoupled signal at one output of the decoupler. One input of the low-pass filter is connected to the output of the decoupler. The low-pass filter is configured to provide a sinusoidal signal for the inductive sensor system by using the inverted signal at an output of the low-pass filter. The sine wave oscillator further comprises a microcontroller that is designed to provide the pulse width modulated signal with a predetermined frequency and a predetermined duty cycle at one pin of the microcontroller.
