The wet case detector uses a sensor bar beneath cases. In the event of a wet case the liquid increases conductivity between the two connections of the sensor bar. This signal is then interpreted by the PLC and based on a user set threshold the case is tracked to a reject station where it will push the wet case off the conveyor. The Wet Case Detection System can also be used to notify production if a programmed number of wet cases has been detected by the sensor bar, indicating a production issue.
