Device for eddy-current control of parameters of articles that consists of generator if sinusoidal oscillations output of which through vortex-current transformer, preliminary amplifier and former is connected to measuring input of phasometer, second output of generator through phase changer and former is connected to support input of phasometer output of which is connected to indicator. Formers of measuring and support channels are arranged as connected in sequence amplifier and hysteresis comparator on operative amplifier with positive back coupling, and phasometer is arranged as connected in sequence circuit of transformation of phase difference to time interval on logical circuit and integrating circuit. |
