| Abstract: | A kind of small-angle eddy-current transducer in form of double E was designed and implemented.The transducer can be used in self-adjustable loops of accelerometers and gyroscopes.According to the theory of equivalent eddy-current,detailed the principle of the angle-displacement eddy-current transducer from angle of theory and calculation and analyzed the form of invert-torque,and deduced its output equation.The experiment results of output characteristic and frequency response are analyzed and shows it is feasible.It can be a guidance for design and use of the same kind of sensors. |
