Bulldog - Conveyor Belt Alignment & Rip Detection System

Bulldog - Conveyor Belt Alignment & Rip Detection System

14 March 2012

The Bulldog is a new addition to 4B’s range of hazard monitoring components. A belt alignment and rip detection switch, this electro-mechanical system has been designed to detect dangerous misalignment of the conveyor and also detection of belt tear damage.

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 15º to trigger an alarm, and 30º to trigger a shut down procedure of the conveyor. The sensors are usually installed in pairs on opposite sides of the belt. A steel flexible wire is set below the running conveyor belt approx 20-30mm attached by a rare earth magnet at each end. If the belt is ripped or damaged the wire is pulled away releasing the magnet connection which in turn will activate a switch.

The system is easy to install and doesn’t require any calibration. Its robust design makes it suitable even for arduous applications such as quarrying and mining.

The 4B Bulldog is ATEX and IECEx approved.

The Bulldog is compatible with 4B’s CBS2A control unit for misalignment sensors and also with the Watchdog complete hazard monitoring system.

The 4B group has been serving the bulk materials handling industry for many years. 4B’s electronics division specializes in level controls, intelligent sensors and safety control systems that prevent costly downtime and minimize the risk of explosion in hazardous areas.
