Sitn.-i: i g current sensor k, proportional to;; to the current 8 of the winding of the eHectroMaiHHTa, is fed to the second input of devices that connect to the information input am1 of 315 9. Condensate (1p 11 amplitude of the detector 9 is charged to an amplitude value of voltage 19, with (H-response current of the operating magnet 3. From the amplitude of the amplitude G1-1Go detector 9, signal 9 comes to the direct input of the comparator 6, to HMnepciuiiM the course of which comes in signal 18 from the current sensor 4. When comparing the inputs to the inputs of the 6th signal of signals 18 and 19, a pulse 2 is generated at the output of the trigger 7, throwing it into a single state: logical at the stage of its output and logical O at its inverse output with the signals of 21 and 16 in fig. 2). The signal 16 at the output of the trigger 7, the input of an element 8 of the controllable input of the controlled switch 2, turns it off, de-energizes the winding of the electromagnet 3. Moreover, the value of the current is maintained at the capacitor 1 of the amplitude detector 9 and is present at its output (the output is repeater 12 voltage, which is the output of the device, until the next measurement cycle. With the arrival of the next pulse 15 from the output of the generator 5, the whole process is repeated. Thus, the introduction of the master oscillator into the known device n monitoring the electromagnet An element and a comparator allows to increase the efficiency of the device and reduce power consumption by applying voltage to the controlled winding of the electromagnet by the time required only for the Fok measurement of the response, and the remaining part of the control cycle of the parameters of the electromagnet occurs when the power supply voltage is off. The device also makes it possible to repeatedly measure the operation current of the same electromagnet automatically.
