Analysis on Measuring Circuit of Pressure Difference Sensor with Magnetic Fluid

Abstract:

Due to many sensing properties, magnetic fluid is used in a novel application--sensor. The measuring circuit is an important part for a sensor. Designing and calculation of the measuring circuit for pressure difference sensor with magnetic fluid were done. The power frequency and the input voltage are the two important factors for the measuring circuit. By experiments and calculations, the power frequency range is 20-70kHz and the input voltage for the circuit is 8V. The measuring circuit for inductive sensors was selected and calculated by analyzing measuring circuit for sensor.
