Abstract
A rotary pressure filter, comprising a filter drum and a housing. A sensor is attached to the housing and emits light through a light-permeable section of the housing in the direction of a filter cake. The sensor receives light reflected from the filter cake through the light-permeable section of the housing. A processing unit compares properties of the emitted light with those of the received light and determines an absolute thickness of the filter cake and/or a change in the thickness of the filter cake over a pre-determined time. The invention further relates to a corresponding method.
