TL;DR: In this paper, an ultrasensitive debris sensor based on microfluidic technology is introduced, which not only achieves the traditional inductance detection, but also proposes a resistance detection method based on coil.

TL;DR: In this paper, a bridge-type inductance sensor with a two-stage filter circuit for high-precision detection of metal debris in the oil is proposed, which mainly consists of two double-wire solenoid coils (as the detection unit and the reference unit, respectively) and a Wheatstone bridge-structure.

TL;DR: An inductive oil pollutant detection sensor based on a high-gradient magnetic field structure is designed in this article, which is mainly used for online detection and fault analysis of pollutants in hydraulic and lubricating oil systems.

TL;DR: The design ideas suggested in this article can not only improve the sample throughput, but also ensure the detection accuracy, and provides a new idea for the development of an inductive on-line detection method of abrasive particle technology.

TL;DR: In this article, an impedance sensor has been proposed to distinguish multi-contaminants in hydraulic oil by adding a built-in silicon steel strip and an external silicon steel Strip with high magnetic permeability to improve the detection sensitivity under inductance and resistance parameters.
