Description

Bulk Pro Conveyor Belt Damage Detectors are designed to shutdown a conveyor system in the event of belt damage. The device warns supervisory personnel of impending belt failures due to rips, punctures, splice failures, and sharp objects protruding through the belt carcass. Model BD-3 conveyor belt damage detectors are mounted in pairs, positioned on both sides of the moving conveyor belt. The units are connected by two spans of aircraft cable. One end of the cable mounts permanently to a support bracket and the other connects to a spring loaded ball located on the detector. The aircraft cables loop underneath the belt from each side crossing at the midpoint. A belt problem is detected when an object or piece of damaged belt hangs below the belt surface and sweeps away one or both cables. As the cable is detached, it pulls a spring loaded ball out of a socket, causing two micro switches to trip. One for annunciation to a PLC or alarm system and the other to shut down the conveyor belt, lessening potential damage and downtime caused without this type of detection.
