Description

Предлагаетс  устройство дл  измерени  перемещени  ферромагнитного материала, позвол ющее, в отличие от существующих устройств, производить измерени  скорости движени  материала путем нанесени  на него лтагнитных меток с частотой, пропорциональной скорости движени . Достигаетс  это применением генератора импульсов переменной частоты, управл емого индикатором фазового сдвига, воспринимающим импульсы генератора и считывающей магнитной головки.A device is proposed for measuring the movement of a ferromagnetic material, which, unlike the existing devices, makes it possible to measure the speed of movement of a material by drawing on it magnetic labels with a frequency proportional to the speed of movement. This is achieved by using a variable frequency pulse generator controlled by a phase shift indicator that senses the pulses of the generator and the readout magnetic head.

Устройство содержи записызагощую / и считывающую 2 магнитные голозки (см. блок-схему), индикатор 3 фазового сдвига, усилитель 4, блок 5 управлени  частотой генератора, генератор 6 импульсов переменно частоты, счетчик 7 импульсов и индикатор 8 скорости.The device contained records of a fast / and 2 magnetic gobblers (see block diagram), phase shift indicator 3, amplifier 4, generator frequency control unit 5, alternating frequency generator 6, pulse counter 7, and speed indicator 8.

Магнитные метки нанос тс  на движущийс  ферромагнитный материал 9 записываюп1ей магнитной головкой У, питаемой от генератора 6 импульсов переменной частоты. Магнитна  метка, проход  прн перемещении материала под считываюндей магнитной головкой 5, наводит в ней импульс напр жени . Импульсы от генератора 6 импульсоз переменной частоты и от считываюи1;ей головки 2 направл ютс  в индикатор 3 фазового сдвига и на вход усилител  4 поступает сигнал рассогласовани , величина и пол рность которого соответствует знаку и величине фазового сдвига указанных импульсов. Сигнал рассогласовани , усиленный, усилителем 4, подаетс  в блок 5 управлени  частотой генератора 6 импульсов. Частота генератора импульсов измен етс  в зависимости от величины и пол рности сигнала рассогласовани  так, чтобы сдвиг . фазы импульсов генератора 6 и импульсов считывающей головки 2 был равен нулю. Таким образом автоматически обеспечиваетс  нанесение на ферромагнитном материале магнитных меток на равных рассто ни х друг от друга независимо от скорости движени .Magnetic marks are applied to the moving ferromagnetic material 9 recorded by a magnetic head Y fed from a generator of 6 variable frequency pulses. The magnetic mark, the passage of the material moving under the reader with the magnetic head 5, induces a voltage pulse in it. The pulses from the generator 6 are a variable frequency pulse and from a readout1; the heads 2 are guided to the phase shift indicator 3 and the input of the amplifier 4 receives an error signal, the magnitude and polarity of which corresponds to the sign and magnitude of the phase shift of the indicated pulses. The error signal, amplified by amplifier 4, is supplied to the unit 5 of the frequency control of the generator 6 pulses. The frequency of the pulse generator varies, depending on the magnitude and polarity of the error signal, so as to shift. the phases of the pulses of the generator 6 and the pulses of the read head 2 were equal to zero. In this way, magnetic tags are equally applied to the ferromagnetic material at equal distances from each other, regardless of the speed of movement.

Рассто ние между метками, равное рассто нию Л между записывающей и считывающей головками, может быть выдержано с точностью,The distance between marks, equal to the distance L between the writing and reading heads, can be maintained with accuracy,
