The Model DB is a cable operated damaged belt detector that looks for punctures, tears, or protrusions through the conveyor belt and provides a means of automatic shutdown to limit the amount of damage to the conveyor belt. The output contacts of the Model DB can control up to two separate circuits, one for machinery shutdown and one for an alarm.
The model DB provides substantial cost savings in replacement belting and downtime associated with belt splicing or replacement.
