Numerical Analysis of Ferrofluid Based Leaning Sensor

Abstract:

Ferrofluid is usually used as an inductive core in leaning measurement sensor because it is provided with both liquidity and magnetism. This paper presents a ferrofluid based leaning sensor, detecting small inclination angles against horizontal plane. An approach of numerical simulation for simulating output characteristic of this kind sensor is proposed. From the result of simulation, it shows, after structural parameters are decided, output voltage signal is linear with pumping frequency which appropriate span is 500Hz～2kHz while output voltage signal is linear with leaning angle.
