Abstract :
A new type of sensor with magnetic fluid (MF) for differential pressure, based on MFpsilas unique features of both liquidity and magnetic properties is introduced in this paper. A model of this sensor is given, and magnetic filed in the model is simulated and analyzed in this paper. The simulation results show that the theory inference is reliable. Some experimental studies on the sensor model are analyzed. The simulation results are compared with the experiment results in some aspects. This sensor has advantages of simplicity of design and construction, high linearity, etc.
