Abstract
PURPOSE: To enable a high-accuracy displacement detection with a simple mechanism, by arranging between signal-receiving means a permanent magnet which causes a ultrasonic wave signal in a magnetic distortion line.
CONSTITUTION: When an exciting pulse ip is supplied from a generator OS to a magnetic distortion line 1, a ultrasonic wave signal is generated at the position of existence of a permanent magnet 4 in the line 1 by an interaction between magnetic field of the pulse ip and that of the permanent magnet 4, and this signal is detected by signal-receiving means 2 and 3 provided at the both ends of the line 1. The pulse ip sets FF1 and FF2 and a signals e1 and e2 from the means 2 and 3 reset FF1 and FF2. And therefore, output of FF1 and FF2 can obtain signals PW1 and PW2 having time widths t1 and t2 which are proportional to distances l1 and l2 between the magnet 4 and the signals PW1 and PW2, and by conducting prescribed calculation by giving these signals to an arithmetic circuit CK, it is possible to obtain an output EO proportional to mechanical displacement.
