Theory Analysis for Magnetic Fluid Inclination Sensor
The paper presents an inclination transducer with magnetic fluid, being dedicated to measure little inclination angles in comparison with a horizontal or a vertical plane. The functioning principle is submitted. The results of theory analysis show that output voltage of sensor and inclination angles are linear dependence. The factors affecting the sensor sensitivity are inspected, which include the exciting signal frequency, the peak voltage and the susceptibility of magnetic fluid.
