Description

ле, подаетс  на вход усилител  7. Благодар  положительной обратной св зи струна 5 получает энергию дл  поддержани  незатухающих колебаний с частотой, практически равной частоте собственныхпоперечных колебаний . Из бункера 1 материал попада На чувствительный элемент 2, который через мембрану 4 воздействует на струну 5, вызыва  изменение ее нат жени  и, тем самым, измен   частоту ее собственных поперечных колебаний.It is fed to the input of amplifier 7. Due to the positive feedback, string 5 receives energy to maintain continuous oscillations at a frequency almost equal to the frequency of its own transverse oscillations. From the bunker 1 material falling On the sensing element 2, which through the membrane 4 acts on the string 5, causing a change in its tension and, thus, changing the frequency of its own transverse oscillations.

образом, определенной величине потока материала соответствует определенна  частота поперечных колебаний струны, которые поддерживаютс  до нового изменени  величины потока материала. Сигнал с усилител  7 попадает на электронный преобразователь 8, св занный со входом частотомера 9, по показани м которого- определ етс  величина потока.материала . I Thus, a certain amount of material flow corresponds to a certain frequency of transverse oscillations of the string, which is maintained until a new change in the value of the material flow. The signal from amplifier 7 goes to an electronic converter 8 connected to the input of a frequency meter 9, according to the indications of which the amount of material flow is determined. I

Предлагаемое устройство содержит М1ЛО передаточных элементов, практически безынерционно, что приводитThe proposed device contains M1LO transmission elements, almost instantly, which leads

к высокой точности измерени  величины потока материала из бункера.to high accuracy of measuring the amount of material flow from the hopper.
