FIELD: instrumentation.SUBSTANCE: proposed device comprises case 1 with cylindrical split bush 3 secured thereto and connected via flexible mechanical link 4 with sensitive element 5 composed by float or buoy. Lateral surface of bush 3 made of spring steel or alloy has circular rows of through cut-outs 6 between which rows of solid flat rings 7 are arranged over bush 3 height. Inside of bush 3 are opposed permanent magnets 9 in the area of rings 7 and rigidly secured therein. Hall sensor 11 is arranged between magnets 9 in the case of nonmagnetic material 10 connected to measuring unit 12. Bush 3 acts as said spring element responding to displacement of sensor 5.EFFECT: higher precision of measurement.7 cl, 3 dwg |
