Abstract:
1. An apparatus for the separation of solids and liquids comprising: a perforated basket which is mounted rotatably within a fixed outer casing, said perforated basket having a perforated outer surface through which liquids are centrifugally expelled from the basket, said fixed outer casing having an inner surface that faces the perforated outer surface of the perforated basket and receives the liquids centrifugally expelled from the basket, a washing liquid supply means for providing washing liquid to the basket and its contents, and a transducer for establishing a control signal representative of the state of liquids centrifugally expelled from the basket, the transducer located in or on the inner surface of said fixed outer casing for monitoring the conductance of the liquids centrifugally expelled from the basket when such liquids impinge on and flow down the inner surface of said fixed outer casing, said transducer comprising at least two electrodes set in an electrically insulating material and having a distance therebetween.
