“…Due to this widespread application area, tilt sensors with different operating principles have been studied both theoretically and experimentally. Research on the magnetic, inductive, capacitive and optical types of tilt sensors has been reported in the literature [1][2][3][4][5][6]. Furthermore, there has been some research on the magnetic and inductive type tilt sensors designed by use of magnetic fluid and magnets [2][3][4].…”

In this study, a simple, adjustable, bidirectional tilt sensor was designed using a pair of linear Hall effect sensors and magnets. Theoretical analysis and experimental results of the sensor system were presented. The working principle of the designed sensor is based on sensing the magnetic field of a mobile magnet which displaces with respect to the tilt angle. Two magnet sets were placed at the two ends of the system to apply repulsive restoring forces on the mobile magnet. The mobile magnet was coated with a light hydrocarbon based ferrofluid as a lubricant to reduce friction. Fixed Hall effect sensors were placed face to face at the two sides of the mobile magnet to monitor the magnetic field of the mobile magnet. It was shown that both experimentally and theoretically, it is possible to measure the approximate tilt angle linearly and quadratically by calculating the sum and difference of the Hall sensor voltages for the relatively small movements of the mobile magnet. Moreover, the system was also examined for the different sets of side magnets. For three different side magnet configurations, approximately 0.7, 1.1 and 1.68 V/rad sensitivity values were observed in the linear range.

Magnetic fluid was a novel functional material with many unique properties, especially in the case that the magnetic field was applied. It was found that the special properties of magnetic fluid were determined by its unique microstructure. Then, the special properties could be understood fundamentally by researching the extraordinary nature of the microstructure of the magnetic fluid. At the same time, it was a good theoretic guidance for the experimental research on the properties of magnetic fluid to make clear about the microstructure model theoretically. Therefore, it was particularly important to study the simulation methods to obtain the microstructure of magnetic fluid. The development of the microstructure simulation methods of magnetic fluid were introduced in this article, and the basic principles of various simulation methods were expounded in detail. The features of each microstructure simulation methods of magnetic fluid were summarized and compared with each other. Finally, the key problems and research direction of the numerical simulation method in the future were described.

“…Magnetic fluids unite their fluid characteristic with magnetic property of those strongly magnetizable materials, therefore they offer various opportunities in a wide area of technical applications. A very large field of applications, especially for measuring devices, is represented by magnetic fluid sensors [3][4][5][6][7][8][9][10][11].…”

Magnetic fluid is usually used as a variably inductive core in inclination measurement sensor because it is provided with both liquidity and magnetism. This paper presents an inductive sensor based on magnetic fluid, detecting level and small inclination angles against horizontal plane. The working principle is introduced firstly, and then the theoretical analysis for principle of detection is deduced. Furthermore, the influencing factors are extracted from the principle function and are testified by experiment results. Finally, one kind of structures is designed to set up experiment. The experimental results showed that the sensor provides a signal proportionally with the inclination angle, which fit well with theoretical conclusion. The sensor sensitivity is proportional with magnetic susceptibility, with pumping frequency, and with the peak value of driving current.
