Abstract
A method for determining the thickness of a charge wall being formed against the side wall of a rotating centrifugal basket by flow of charge material into the basket comprises the steps of establishing a capacitance across the charge space of the basket and sensing any change of capacitance which results as the charge wall thickness is increased by the flow. An apparatus for determining the thickness of the charge wall formed against the side wall of the centrifugal basket includes an electrically conductive plate disposed in the basket inwardly of the charge space and a source of voltage for establishing an electric field between the plate and the side wall. A capacitance sensor senses any change in the established capacitance resulting from the formation of a charge wall in the basket.
