Description

Изобретение относитс  к технике магнитных измерений и может служить дл  контрол  параметров магнитного пол .The invention relates to a technique of magnetic measurements and can be used to monitor magnetic field parameters.

Известные устройства дл  измерени  магнитной индукции, содержащие пьезозлемент с закрепленным на нем  корем из магнитом гкого материала, не позвол ют получить точные результаты.The known devices for measuring magnetic induction, which contain a piezoelement with a crust of magnetically soft material fixed on it, do not allow to obtain accurate results.

С целью повышени  точности измерений предложенный датчик снабжен двум  синхронно возбуждаемыми пьезоэлектрическими пластинами одинаковой частоты и среза, между которыми зажат  корь.In order to improve the measurement accuracy, the proposed sensor is equipped with two synchronously excited piezoelectric plates of the same frequency and cut, between which the measles are clamped.

На чертеже показан предложенный датчик.The drawing shows the proposed sensor.

Две пьезоэлектрические пластины 1 одинаковой частоты и среза, между которыми зажат  корь 2 из магнитом гкого материала, жестко закреплены в кристаллодержателе 3. Пьезоэлектрические пластины синхронно возбуждаютс  от генератора 4. Изменение частоты колебаний пьезоэлектрических пластин измер ют регистрирующим прибором 5.Two piezoelectric plates 1 of the same frequency and cut, between which the bark 2 of magnetically soft material is clamped, are rigidly fixed in the crystal holder 3. The piezoelectric plates are simultaneously excited by the generator 4. The change in the oscillation frequency of the piezoelectric plates is measured by a recording device 5.

При внесении  кор  в измер емое магнитное поле полюса 6 усилие, действующее на  корь, вызывает изменение частоты колебаний пьезоэлектрических пластин. При отсутствии магнитного пол  механические усили , сжимающие или раст гивающие  корь от колебаний синхронно возбужденных пьезопластин , совпадают по направлению н величине, и  корь остаетс  в покое.When a core is introduced into the measured magnetic field of the pole 6, the force acting on the measles causes a change in the oscillation frequency of the piezoelectric plates. In the absence of a magnetic field, the mechanical forces that compress or stretch the measles against oscillations of synchronously excited piezoplates coincide in direction and size, and the measles remain at rest.

Изобретение позвол ет измер ть параметры как переменного, так и посто нного магнитного пол .The invention makes it possible to measure the parameters of both an alternating and a constant magnetic field.

Предмет изобретени Subject invention

Датчик дл  измерени  магнитной индукции, содержащий неподвижно установленный в корпусе пьезоэлемент с закрепленным на нем  корем из магнитом гкого материала, отличающийс  тем, что, с целью повыщени A sensor for measuring magnetic induction, containing a piezo element fixed in the housing with a bar of magnetic material fixed on it, characterized in that, in order to increase

точности измерени , он снабжен двум  синхронно возбуждаемыми пьезоэлектрическими пластинами одинаковой частоты и среза, между которыми зажат  корь.measurement accuracy, it is equipped with two synchronously excited piezoelectric plates of the same frequency and cutoff, between which the measles are squeezed.
