Title: Measuring gap width between material pressing bodies - ascertaining distance between body projections to enable pressed material density measurement
Inventor: GATERMANN BODO
IPC: G01B21/16
Filed: 1980-06-26
Abstract: The measuring method is applicable to a gap between surfaces of two bodies which are to be forced together by forces acting outside the surfaces on projections deforming under load. The method enables a very accurate measurement of the width of the gap and hence of the density of the material pressed within it. The projections have extensions unaffected by the forces and measurement points between which are measurement distances lying on lines parallel to the line along which the body separation is to be determined. The ratio of the decreases in the two distances is independent of the applied force so that the relationship is known between the width of the gap, the first measurement distance and the projection position.
