Wet Case Detector


Detects wet bottom cases that result from leaking or broken bottles within the case.  Wet cases are detected and rejected before reaching the palletizer and causing damage to other cases on the skid.  The Wet Case Detector is a quality control unit that increases line productivity and reduces customer complaints.  A series of spring-loaded probes positioned between the rollers on the case conveyor measure conductivity of all cases on the line. When the probes come into contact with a wet case, they detect increased conductivity and send a signal to the controls. The probe assembly is easily bolted to the under side of the existing conveyor.
