Abstract
This invention relates to a device of electrodes for measuring water content in foundry sand, an apparatus for measuring water content in foundry sand, and a method and an apparatus for supplying water to a sand mixer. When the prior art device for measuring water content in the foundry sand is disposed in it, the size or shape of the device of the electrodes is limited. To solve this problem, the device of the electrodes for measuring water content in the foundry sand by supplying an electric current to it is comprised of a plurality of conductive elementsconcentrically disposed with certain intervals between them in a longitudinal direction, wherein the elements form an annular shape, a retaining elementto retain the plurality of the conductive elements, wherein the retaining elementhas an electrical insulating property and a cylindrical shape having the same diameter as the conductive elements, and the two conductive wiresto connect alternate respective elements of the plurality of conductive elementsso that the conductive elementsform two poles, wherein the two conductive wirespass through the cavity in the retaining element
