Description
(54) УСТРОЙСТВО ДЛЯ ЭЛЕКТРОМАШИТНОГО НЕРАЗРУШх ЮШЕГО КОНТРОЛЯ ИЗДЕЛИЙ(54) DEVICE FOR ELECTROMASHIT NON-DESTRUCTIVE SOUTH CONTROL OF PRODUCTS
Изобретение относитс к cpeдcтвa 1, не измен ющим структуру объектов контрол , и может быть использовано дл контрол качества ферромагнитных материалов.The invention relates to medium 1, which does not change the structure of control objects, and can be used to control the quality of ferromagnetic materials.
По авт. св. №426184 известно устройство дл электромагнитного неразрушающего контрол ферромагнитных изделий, содержашее многообмоточный трансформаторный преобразователь и св занный с ним индикатор сигналов, выполненный в виде каналов амплитудно-фазовочастотной селеыщи. Однако достоверность контрол анизотропных изделий известным устройством недостаток на , так как результаты контрол определ ютс по соотнощанию гармоник сигналов преобразовател .By bus. St. No. 426184, a device for electromagnetic non-destructive testing of ferromagnetic products is known, which contains a multiwinding transformer converter and a signal indicator associated with it, made in the form of amplitude-phase-frequency channels. However, the reliability of control of anisotropic products by a known device is disadvantageous, since the results of the control are determined by the ratio of the harmonics of the converter signals.
Цель изобретени - повышение достоверности контрол изделий. Дл этого устройство снабжено детектором отношени среднего значени напр жени и амплитуды гар МОНИКИ, включенным между вторичной обмоткой и выходом канала амплитудно-фазовочас тотной селекции.The purpose of the invention is to increase the reliability of control products. For this, the device is equipped with a detector of the ratio of the average value of the voltage and the amplitude of the harmonic MONICA, connected between the secondary winding and the output of the amplitude-frequency-frequency selection channel.
На чертеже изображена блок-схема предложенного устройства.The drawing shows a block diagram of the proposed device.
Устройство содержит источник 1 синусоидального тока (возбудитель), трансформаторный преобразователь 2, селективный усилитель 3 выбранной гармоники, амплитудный детектор 4, детектор 5 среднего значени Э.Д.С., детектор 6 отношений и регистратор 7.The device contains a sinusoidal current source 1 (exciter), a transformer converter 2, a selected harmonic selective amplifier 3, an amplitude detector 4, a mean voltage detector 5 E.D.S., a ratio detector 6 and a recorder 7.
Устройство функционирует следующим образом .The device operates as follows.
