то есть, при заданной частоте вибрации ток в рамке гальванометра пропорционален смещению, т. е. интегралу от скорости вибрации, равному интегралу от э. д. с. С.that is, at a given frequency of vibration, the current in the frame of the galvanometer is proportional to the displacement, i.e., to the integral of the velocity of vibration equal to the integral of e. d. WITH.

Figure 2 shows the general scheme of the device, where t, mz are the masses (magnets) of the vibration sensors, K, Kiz, Kzi-springs, and LII, i; 2. 21 and Z.22 - INDUCTANCE of the coils of vibration sensors, labeled with letters L and B, and intended for measuring vertical and horizontal vibration. The letter P is an indicator representing a detector index with a cuprope bridge K, a sensitive galvanometer G included in an electrical integrating circuit with capacitances d and C. The symbols Pn and P represent the switches of the Integral sensors and measuring ranges, respectively, and PI and - fitting matches. .

Как следует из приведенного описани , устройство не требует дополнительного питани . Необходима  электроэнерги  вырабатываетс  за счет самой вибрации испытуемого Объекта.As follows from the above description, the device does not require additional power. The required electrical power is generated by the very vibration of the Object under test.

Предмет изобретени Subject invention

Устройство дл  измерени  вибраций с применением электромагнитных виброметров, индуктируема  на обмотках которых э. д. с. предназначена дл  подачи на интегрирующую схему, состо щую из конденсатора , параллельно к которому подключен измерительный прибор, отличающеес  тем, что, с целью выделени  и измерени  составл ющих механических колебаний одной определенной частоты, величина емкости конденсатора подобрана такой, чтобы последний вместе с индуктивным сопротивлением включениого параллельно ему прибора, образовал контур , настроенный на выдел емую частоту колебаний.A device for measuring vibrations with the use of electromagnetic vibrometers, induced on the windings of which e. d. designed for supplying an integrating circuit consisting of a capacitor in parallel to which a measuring device is connected, characterized in that, in order to isolate and measure the components of mechanical oscillations of one specific frequency, the capacitor capacitance value is chosen so that the latter together with the inductive impedance parallel to it, the instrument formed a contour tuned to the selected oscillation frequency.
