Abstract

PURPOSE:To perform highly precise measurement with no contact by applying pulse modulation to high-frequency current by means of a pair of inductor gears provided coaxially, respectively, and by finding the relative displacement angle due to the torsion of the inductor gears from the difference in output of both gears. CONSTITUTION:When the side of a driving shaft 9 is driven by a primer mover and the side of a loaded shaft 10 is rotated in connection with a load, a torsion corresponding to the size of the load is caused in a torsion shaft 8. To the detecting wire wheels 5 and 6 of detecting ends 3 and 4 provided in the gears 1 and 2 in opposition to each other, high-frequency current given by a high-frequency exciting winding 7 is delivered with modulation. And, the outputs of the respective detecting wire wheels 3 and 4 are ooerated differentially and counting is made in a fixed cycle, whereby the relative displacement angle is found.
