Belt alignment switch protects conveyor belts from damage

Conveyors help automate processes by carrying products from one area to another. However, all of the efficiencies gained by introducing conveyors to a process could be lost if they are not properly cared for.

Enter the Model BA100-1 Conveyor Belt Alignment Switch, a device that protects conveyor belts from damage due to belt misalignment or runoff. These controls are used in pairs with one switch placed on each side of the conveyor belt. Each unit can be equipped with two limit switches to produce signals indicating belt misalignment at two deviation points. The first signal point could indicate small belt deviation by sounding an alarm. The second signal point could guard against extreme belt runoff by shutting down the conveyor. 

Each control consists of an aluminum housing with a red epoxy-coated roller that is adjustable up to 90 degrees in both directions and is positioned approximately one inch from the conveyor belt. The roller arm is spring loaded for automatic reset, though manual reset is available. The switch actuation points are adjustable from zero to 45 degrees by a simple change of the actuating cam(s). The model BA100 can be furnished with general purpose or explosion-proof construction. Cast iron and epoxy-coated housings are also available.

The Model BA100-1 Conveyor Belt Alignment Switch, from Electro-Sensors, is a conveyor belt protection system that saves the money, process downtime and product loss associated with replacing a damaged conveyor belt. The switch is available through Pickering, Ont.-based Durham Instruments.
