Abstract
A novel displacement transducer using the secondharmonic type of magnetic modulator is proposed to detect a static displacement as low as 0.1 ¿m. The operation of transducer is based on modulating and amplifying the magnetizing force proportional to the input displacement by means of the second-harmonic type of magnetic modulator. In order to enhance signal sensitivity, 4 pole-pieces type dc bridge and differential type moving detector are used for modulation circuit of this transducer.
