  • Device for measuring mass of consumable electrodes being remelted in electric furnaces
    Patent number: 4002816
    Abstract: The device of the invention comprises a hollow cooled rod on which a mass transmitter for a consumable electrode is secured. The casing of the mass transmitter accommodates two bellows of different diameter operating as a sensitive element interacting with an annular projection on a bar shifting along the axis of the bellows and acting as a movable element. The bellows are arranged one above the other along the bar axis, one end of each of the bellows being fixed on the annular projection and the other, on the casing. One bar end face is rigidly associated with the consumable electrode holder and the other one has a recess filled with a current-conducting liquid medium receiving the rod end face directed towards the bar. The bellows space defined by the bellows proper, the casing and annular projection is filled with a liquid, variations in the pressure thereof being indicative of the mass of the consumable electrode.
