Abstract
PURPOSE: To obtain a measuring apparatus for displacements that can compare a measured signal with the reference value just prior to being measured so that automatic offset correction can be carried out without detecting a passing matter.
CONSTITUTION: The instant that the measuring value eb is indicated as a measuring input signal A, the value is impressed on the input end of one side of a differential amplifier 14 and a measuring input signal A is input behind time to the input end of the other side of the differential amplifier 14 through the hold circuit 13 and the output H of the differential amplifier 14 takes a positive value. When this output H becomes greater than the voltage of the comparison power source 17, the output of the comparator 16 becomes positive and opens a switch 12. Therefore, the output G of the hold circuit 13 does not rise like dotted arrows shown in Fig. (a), holds the feference value ea obtained the instant the eab is input and supplies it to the differential amplifier 14. Thus, the differential amplifier 14 always inputs the difference between the measuring value eb and the reference value ea.
