Abstract

A measurement apparatus for use with a molding machine comprising an electrical measurement value transmitter responsive to distance variations for determining the degree of filling of a casting mold, the mold parts of which are supported against one another in the closed position of the mold by means of at least one fluid-operated, for instance, hydraulic displacement device incorporating a closure cylinder and closure piston. One transmitter component of the electrical measurement value transmitter is operatively coupled with the closure cylinder and a second transmitter component of the measurement value transmitter is operatively coupled with the closure piston.
