Abstract
PURPOSE:To detect a rotational speed even at the time of a low speed, by utilizing the intensity change of the electric field generated between a rotor and a detection head in the detection of the rotational speed. CONSTITUTION:Tooth parts 2 and tooth spaces 3 are alternately formed to the outer peripheral surface of a conductive gear rotor 1 making one revolution along with an article to be measured and a detection head 4 is arranged in the vicinity to said outer peripheral surface. This detection head 4 has a main body part 5 and an electric field intensity sensor 6, and the intensity change of an electric field due to the rotation of the rotor 1 is detected by the electric field sensor 6. The detection signal of said sensor 6 is pulsated to be counted at every unit time and the rotational speed of the article to be measured is calculated.
