Abstract
PURPOSE: To detect and display the rotating speed over a wide range accurately with a simple constitution, by the time distance operation and digital conversion for the periodic pulse being the detected output of rotation angle at each period.
CONSTITUTION: The approach of the detected object 2 such as magnetic substance in revolution is detected with the detector 3 such as high frequency oscillation type proximity switch to pick up the pulse signal every equal rotary angle and it is fed to the input wave shape circuit 5 to eliminate unnecessary pulse component. The pulse signal wave shaped triggers the time sharing signal generator 7 to pick up the binary output in opposite phase each other, and it is inputted to the straight line intergrator 9 to obtian the signal of integrated voltage in inversely proportion to the number of revolutions. Since this signal is continuous pulse train, the counter 23 is instantly reset with the output differentiating the leading of the H level output of the signal generator 7, and the content of the counter 23 is latched by taking the pulse differentiating the leading of the output waveform of the comparator 15 as the strobe signal of the latch circuit 25, and the content is decoded and displayed on the display unit 27.
