MODEL BM-3 BELT BELT MISALIGNMENT SWITCH

The Model BM-3 Belt Misalignment Switch detects conveyor belt misalignment. Two (2) micro switches can trigger an alarm or conveyor shutdown to protect the conveyor belt from damage when belt drift occurs.

When the belt runs off center, the roller arm will be deflected from its normal vertical position and at a preset angle activates the first micro switch which can output an alarm. When the belt further displaces the roller arm at a preset angle, the second micro switch will be activated to shut down the conveyor before damage can occur to the belt or plant.

The BM-3 belt misalignment switches are usually installed in pairs on both sides of the belt and positioned at a distance between 1- 6 feet from the head or tail pulley. Typically, it can be mounted on the top or bottom of the conveyor stringers with the actuating arm trained 1-3 inches away from the outside edge of the belt.

Features:

• Universal mounting, usually at the top or the bottom of the conveyor belt stringer.

• Robust die cast aluminum housing with epoxy based powder coat finish and all stainless steel external hardware.

• Integral cover, permits easy access to the wiring terminals and adjustments.

• Easily removed cover without the requirement of removing the roller arm.

• Roller arm bearings rated to 5000 RPM, suitable for belt speeds up to 1250 FPM.

• Normal roller arm angle adjustment within + 22.5 degrees.

• Bi-directional roller actuating arm suitable for installing on both sides of the conveyor.

• Provides an alarm when the roller actuating arm moves 10 degrees and shutdown with an actuating angle of 20 degrees.
