Description
The range of Bulldog misalignment and rip detection electro-mechanical switches are designed to detect dangerous misalignment and/or rip on open belt conveyors.
The switch will detect horizontal misalignment of belts. When contact is made with the roller, the roller arm will be forced to pivot by the belt, activating a switch at 20º to trigger an alarm, and 35º to trigger a conveyor shut down. The switches are usually installed in pairs on opposite sides of the belt.
For belt rip detection, a flexible cable is set below the running conveyor belt approximately 20-30mm. It is attached by a rare earth magnet at each end and if the belt is ripped or damaged, it will impact the cable to disconnect the magnet from the Bulldog and trigger a conveyor shutdown.
