SENSOR FOR MEASURING THE FORCE PRODUCED BY THE DISPLACEMENT OF SAND DURING THE COMPACTION OF CLAY-BONDED MOULDING MATERIALS IN THE PRODUCTION OF CASTING MOULDS

摘要

The invention relates to a sensor for measuring the force produced by the displacement of sand during the compaction of clay-bonded moulding materials in the production of casting moulds. The invention is characterised in that the sensor comprises a dynamometer (9), a displaceable sensor probe (1), which is located in the housings (2) and (3) that form a cavity and a spring (4) that is prestressed between the sensor probe (1) and the dynamometer (9), said elements being positioned in the direction of the axis.
