The principle of construction of an eddy current detector for monitoring the cleanliness of the working fluid of hydraulic systems and aircraft engines is described. The parameters of the impurity particles are measured with an eddy current transducer included in an active oscillator circuit. The results of experiments with particles of copper and steel grade ShKh-15 are presented. The limiting sensitivity of the detector is obtained from the diameter of the detected particles.
