SRI Chute Height Sensors measure the height of bagasse in a Donnelly chute above the mill, and is typically used in the control system for the flow of bagasse through a sugarcane crushing mill or, for the first mill, to control speed of the prepared cane feed elevator.
The height is measured via stainless steel electrodes installed in the chute wall. By measuring conductivity to determine the presence of material at each electrode, chute height control is an important regulating component that evens out bagasse flow through the mill. Its output signals are used to control feed rate, giving maximum sugar extraction, lower mill stress and reduced power use.
