Description
(54) МАГНИТОСТРИКЦИОННЫЙ ПРЕОБРАЗОВАТЕЛЬ вон в области катушек подмагничиваетс посто нными магнитами 6. Выходной величиной вл етс отношение частоты ультразвуковых колебаний в опорном канале преобразовател к частоте уль- развуковых колебаний в его рабочем канале Q п 0 f 1. . Так как Q не зависит от скорости распространени ультразвука в звукопроводе, тем самым обеспечиваетс высока точность измерени перемещений. Использование в качестве вторичного прибора измерител отношени частоты, имеющего более простую структурную схему, упро щает устройство и снижает его стоимость. Предмет изобр етени Магнитострикционный преобразователь линейных перемещений, содержащий звукопровод с демпферами на его концах и рабочую пару катушек /передающую и приемную/, отличаюн1ийс тем, что, с целью упрощени структуры вторичного прибора, на звукопроводе дополнительно к рабочей паре катушек устанавливаетс на фиксированном рассто нии друг от друга опорна пара катушек /передакица и приемна /, отделенна от рабочей пары катушек вспомогательным демпфером причем информацией о перемещении служит отношение частоты циркул ции ультразвуковых колебаний в опорном канале к частоте циркул ции ультразвуковых кол&баний в рабочем канале преобразовател .(54) MAGNETOSTRICTING TRANSMITTER in the region of the coils is magnetised by permanent magnets 6. The output value is the ratio of the frequency of ultrasonic vibrations in the reference channel of the transducer to the frequency of ultrasonic vibrations in its working channel Qn 0 f 1.. Since Q does not depend on the speed of propagation of ultrasound in the duct, thereby ensuring high accuracy of measurement of displacements. Using a frequency ratio meter as a secondary instrument, which has a simpler block diagram, simplifies the device and reduces its cost. Subject of the invention The magnetostrictive linear displacement transducer, containing a sound pipe with dampers at its ends and a working pair of coils (transmitting and receiving), is different in that, in order to simplify the structure of the secondary device, on the sound line in addition to the working pair of coils, the coil support pair / transfer and receiver / is separated from one another and separated from the work pair of coils by an auxiliary damper, the information about the movement being the ratio of the frequency of circulation ultrasonic oscillations in the reference channel to the frequency of ultrasonic circulation count & transducer-oscillations in the working channel.
