The invention relates to measuring equipment and can be used to simulate the vibratory during certification eddy current sensors designed to control the rotational speed, the linear displacement of the gap and the vibration level of rotary machines, turbines and other machinery in the power industry, the oil and gas industry and other fields.; The apparatus comprises an inductor, a shunt resistor and a control generator.; What is new is the introduction of a capacitor circuit which forms the coil simulator oscillation circuit, and a diode bridge is used as the shunt resistance. The technical effect of the utility model is to simplify the eddy current sensor and the ability to automate the process parameter measurement sensors and to carry out computer processing of the results of their evaluation.; 1 Fig.
