The design of otsu-yusits to the measuring technique, namely, to devices for determining or determining the conductivity of materials or products, non-nanoscale nanoparticles, and irregular hydrostatic pressure.

Known devices contain wet water | 1, the hydro chamber in which the material (or article) to be examined is placed and the measuring instrument | 1NI1 irnbor with a pointer, serving as a tL1 for 041 pitch of its contents. Ions are used either as iRo (alimated spring with load, suspended from the upper wall (lid) of the hydrocamera, or non-deformable and eccentricity associated with tarring and foams.

11a; 1, the operation of the measuring instruments in these devices is a linear equality between the magnitude, the working section of the scale of measurements and the magnitude of the vertical, and the Helium of the test specimens, which leads to the complexity of these devices and the low accuracy of the measurements to be taken.

The purpose of the invention is continuous coitrol for changing the material under study, depending on the exposure time, pressure, pressure, pressure change in the hydroenvironment, as well as increased accuracy, expansion of the measurement range and reduction of the device dimensions.

This is achieved by the fact that the measuring device is identified in the form of a lock of a second vessel, for example, a bellows, communicating with a tube with a pointer. The vessel and the tube are aspirated by a working fluid that is not miscible with the global environment. In the internal nolostn, the sllfoia is set up to be regulated and “a”, and the container with the test material is located above

SOS) HOUSE.

The drawing schematically shows the proposed device, the neurobal section.

The device contains a hydrocamera / mai meter 2. Inside the hydrocamera, the size of the container is “3” associated with the NCM instrument. 1 about 1 container 3 serves to work; | The material under study, LL | Example of all-nye polystyrene granules 4, is perforated to remove air and free penetration into its hydro-environment, water is used, it is found in the hydraulics, and is used in compression material, e.g. The measuring reservoir is a transferee vessel 5, changing the volume of a node by the influence of a c; i: ibi, and a measuring tube 6 connected to a closed vessel 5, exchanged outside the hydraulic chamber 1 and associated with its free volume the end. The working fluid 7, the paioli closed vessel 5 and the measuring tube 6 are not mixed with the hydro environment.

located in the hydraulic chamber. The buoyancy of the investigated b, b, raz.tsa is determined according to the scale of measurements 8.

In order to expand the diaozone and to measure the magnitude of the numerical strength of the materials under study, the Instrument Equipments with control spring 9, as well as the movable sleeve 10 and screw 11, in which the spring B is actuated and the dribor is adjusted, are measured. To fill the instrument with the working fluid, to drain it and to install the non-flow | 0: GO iB level of the measuring tube, during its adjustment the instrument is equipped with taps 12 and 13, and in the upper part of the closed vessel 5 there is a hole closed by a stopper (not shown).

The hydrochamber / is connected to the pressure control system (shown in the drawing) with the pipeline 14.

The setting of the measuring device and the establishment of the liquid working fluid in the measuring tube, in the initial (zero) state, are removed after the empty container is attached to the measuring device and filled with a hydraulic chamber / water.

The test material (or product) in the container and attachment last to the measuring instrument, using the scale measured in the buoyancy scale and measurements 8, determines the floating buoyancy of the test sample in the absence of an overpressure. With an increase in pressure in the hydrochamber / sample under investigation, it is compressed and, decreasing in volume, loses part of the buoyancy. Under the influence of the container 3 which has changed (increased) from the side of the container 3 to the closed vessel 5, the volume of the latter changes, which displaces part of the working fluid from it and a corresponding increase in the height of its column in the measuring tube 6, balancing the resultant force acting on the closed vessel 5 The change in the buoyancy of the sample under study, depending on the change in the hydrostatic pressure, is recorded on the measurement scale 8. The pressure in the hydrochamber 1 is then determined using a pressure gauge 2.

If necessary, extend the measurement limit of the device by means of the screw 11 and move the sleeve W and put the spring 9 into operation, the balancing forces of which are directed in the same direction as the balancing forces of pressure of the working fluid column in the measuring tube. In this case, the absolute value of the price divided by the measurement scale 8 increases.
