Method for measuring the thickness of a solids layer on the peripheral wall of a centrifuge drum, and device for carrying it out

摘要

To determine the thickness of a solids layer (38), which has permanently formed on the peripheral wall (12) of a centrifuge drum (10), a measurement container (34), into which the liquid ring (28) sinks when the centrifuge is switched off, is placed underneath the open centrifuge bottom (20). The corresponding level change in the measurement container (34) is determined by level sensors (42, 54) located there. An alarm is triggered when the level change falls below a minimum. <IMAGE>
