j U- 1 The invention relates to means of measuring the "first technique" and can be used to record the parameters of oscillatory processes in mechanical systoles. An integrated level vibration sensor is known that includes a housing filled with a working fluid, an inertial piston with a reverse valve installed on springs in a working chamber connected to the atmosphere, sensitive and recording epitome 1) The device’s disadvantage is a narrow frequency and amplitude range of measurements parameters vibrapsh. The closest technical (to the proposed one is a displacement transducer, containing a vessel filled with liquid, coupled with the object of investigation, caused fluid oscillations and measurement channel 2. A disadvantage of this device is the low accuracy of measurement of oscillation parameters. The purpose of the invention is to accurately measure displacement measurements. The goal is achieved by the fact that the displacement sensor, containing a liquid filled vessel, associated with the object of interest of the oscillating fluid pathogen and measurement channel, is provided with an opaque casing, the vessel is made of translucent material, the liquid is colored, and the measurement channel is coaxially mounted on both 29 side of the vessel of the light source and receiver. . The drawing shows the functionality of a motion sensor. The displacement transducer contains a vessel 1 made of a translucent material, filling in its colored liquid 2, the causative agent of 3 oscillations of the liquid, conjugated with the object 4 of the research, filled in the form of a rod. The measuring gauge consists of coaxially mounted -. on both sides of the vessel 1 of the source 5 of the light and of the photosensitive nanometer 6. The sensor is placed in an opaque skin 7s.e7. The displacement sensor works as follows. In the event of a periodic displacement of the object 4 research with PSC--. By means of an exciter 3 fluid oscillations create pressure drops from these movements. This changes the tone of the color with which the liquid 2 is colored. After switching on the source 5 of the light, the photosensitive receiver 6 changes its parameters (for example, co-op) according to the law of change in the intensity of the light passing through the vessel 1 and liquid 2, the law and value of which 1 correspond to the parameters of movement of the accelerator € 3. The use of the proposed displacement transducer improves the quality of experimental work by varying the sensitivity and accuracy from the oscillations of the oscillation parameters and reduces the sensor dimensions.
