The first sensor is positioned proximate the inlet of the housing and along a lateral side of the conveyor or along a first cantilever arm extending laterally across the conveyor. The second sensor is positioned within the processing zone. The third sensor is positioned proximate the outlet of the housing and along a lateral side of the conveyor or along a second cantilever arm extending laterally across the conveyor.
