    The invention relates to a measurement technique and can be used to measure vibrations.
    A device for measuring oscillations is known, comprising a housing in the form of a cylinder with two openings made opposite to each other, and acceleration sensors 1 arranged therein.
    A disadvantage of the known device is the low measurement accuracy due to the influence of the mass of the housing and the sensors on the measurement result.
    The purpose of the invention is to improve the measurement accuracy.
    The circuit is achieved by the fact that a device for measuring oscillations, comprising a cylinder-shaped body, with two openings opposite each other, and acceleration sensors located therein, is provided with a compression spring arranged between the acceleration sensors and the spring compression mechanism arranged inside the cylinder, made in the form of a flange, articulated on it cams, levers, which are biased interconnected to each other and C cams, and a shaft mounted to move along a cylinder and pivotally connected to ychagami,
    FIG. 1 is a schematic diagram of the proposed device; in fig. 2 is a section A-A in FIG. one.
    The device for measuring oscillations comprises a housing in the form of a cylinder 1 with two openings opposite each other, and the acceleration sensors 2 and 3 located therein, inside the cylinder 1 a compression spring 4 mounted between the acceleration sensors 2 and 3, and a compression mechanism spring 4, made
    in the form of a flange 5, cams 6 and 7 pivotally mounted thereto, and levers 8 and 9 pivotally interconnected with each other and cams 6 and 7, and a stem 10 mounted for movement along a cylinder 1 and pivotally connected with levers 8 and 9.
    In addition to the toga, the device contains an indicator 11.
    The device works as follows.
    The spring 4 is compressed using a flange 5, cams B and 7 pivotally mounted thereto, levers 8 and 9 pivotally connected to each other and with cams b and 7, and a stem 10 mounted for movement along a cylinder 1 and pivotally connected to the levers 8 and 9. The device is inserted into the controlled pipe 12, the sensors 3 and 2 of the accelerations are brought into contact with the walls of the pipe 12, they measure the vibrations with the help of the latter and the indicator 11 connected to them. 2 and 3 mustache Oren and spring 4. Moreover, one of the sensors 2 and 3 may sense vibration accelerations in the radial and the other - in the axial direction relative to the pipe axis 12.
    After the measurement is completed, I compress the spring 4 using the flange 5, the cams 6 and 7 pivotally mounted on it, the levers 8 and 9 pivotally connected to each other and with the cams b and 7, and the rod 10. Next, the output device comes out of the pipe 12.
    Thus, because only the mass of the acceleration sensors and the compression spring affects the measurement results, the measurement accuracy is improved.
