Abstract

PURPOSE:To prevent the foreign matter in molding and from being caught by an electrode and obtain accurate electric resistance value (it is expressed in terms of moisture value) by intermittently and vertically moving the electrode for measuring the electric resistance of the molding sand. CONSTITUTION:An electrode supporting body 8 buried with an electrode 7 is mounted to the bottom end of a supporting plate 9 which is made vertically movable by a parallel link mechanism. The top end of the supporting plate 9 is connected via a chain 17 to the dog 18 of a piston rod which is moved vertically by a cylinder 19. The terminal of a limit switch 20 is abutted on the dog 18. The above-mentioned device is used and the moisture of molding sand is measured by abutting an electrode 2 on the molding sand 2 conveyed in an arrow A direction, measuring the electric resistance of the molding sand and expressing the obtained value in terms of degree of moisture, wherein catching of the foreign matter 21 mixed in the molding sand by the electrode supporting body 8 is averted by vertically moving electrode intermittently at this time (during ascending of the electrode, the contact of the dog 18 and the terminal of the limit switch 20 is broken and the measurement of the resistance value is suspended by the signal thereof).
