“…Among them, the base carrier liquid is generally water, grease, synthetic oil, hydrocarbon, polyphenyl ether or minerals. As new functional materials, magnetic liquids have the liquid fluidity and the magnetic properties of solid magnetic materials [1]. Compared with conventional acceleration sensors, the points of acceleration sensors incorporating magnetic liquids include shock resistance, low energy consumption, fast response, and reliability [2].…”

In order to solve the shortcomings of traditional magnetic liquid acceleration sensors such as complex structure, large size and low frequency range of use, this paper designs a single-degree-of-freedom magnetic liquid acceleration sensor. The suspended magnet and the adsorbed magnetic liquid are used as the inertial mass, and the copper coil is collected to produce current for acquisition and analysis to determine the value of acceleration. Through experiments, the inertial mass vibration amplitude and current magnitude of this accelerometer are analyzed from the three influencing factors of the spacing between the inertial mass block and the fixed ring magnet, the mass size of the inertial mass block and the damping ratio. The influence of the relevant variables on the phenomena generated by the magnetic liquid acceleration sensor is studied.

For many engineering fields, the air flow should be controlled into a safety range to ensure the production safely. A novel flow measurement device was designed for large safety range. A separable structure of the device was proposed to meet the convenience to carry. Magnet and magnetic fluid was selected as an inducting core. The characteristics of the inducting core were researched. The working principle of the measurement and alarm device for air flow safety was introduced and analyzed. The separable structure was designed to achieve two modes of the measuring and alarm device that one mode is for measuring and alarming work and the other mode is for storing and transporting conveniently. A pipe was designed for the air to pass through. Two coils were designed and chosen to be set up at two ends of the pipe to detect the changes of the internal magnetic flux and then alarm for the changes. An adjustment element was designed and set into the pipe to adjust the position of the inducting core to satisfy the requirements of the working conditions. The designed device is feasible to keep the air flow safely and to alarm when the air flow exceeds safety range.
