Description

Bulk Pro Conveyor Belt Misalignment Switches are designed to prevent damage to belts and equipment due to a misalignment condition of the conveyor belt. They are normally located one to six feet from the head and tail pulley on both sides of the belt with the roller arm positioned approximately one inch from the normal belt position. If the belt begins to wander, it makes contact with the roller arm causing it to spin. As more force is applied to the roller arm it will rotate away from the normal position and at 10° it will actuate the first alarm SPDT micro switch. The first micro switch will annunciate the alarm condition to the control system so corrective action can be taken. If the belt continues to track off it will cause the roller arm to rotate from its 10° position to the 20°position, which will activate the second alarm SPDT micro switch. This second micro switch is wired into the motor starter of the conveyor belt to shut it down. Conveyor belt misalignment switches reduce downtime and maintenance associated with belt tracking problems.
