Abstract

The magnetostrictive linear displacement transducer is a kind of transducer that can calculate the distance between the measured point and the receiving point by measuring the time difference between the excitation and the receipt of elastic waves. This paper describes research work in a kind of magnetostrictive linear displacement transducer based on Wiedemann effect, focusing on the enhancement of the torsional strain pulse generation with the aim of obtaining high measurement accuracy. The pulse width and amplitude of the exciting pulse current are optimized for increasing the output signal amplitude of torsional wave sensing coil. The results of experiment show that through the parameter optimization the electric reply signal is increased, the signal-to-noise ratio of sensing coil output can be improved.
