On a conveyor and elevator they should be installed on the tail drum, tail roller, snub roller, gravity take up roller or any roller that is driven by the conveyor belt itself.

Alternatively the Rotech Wheel Driven Motion Sensors can be fitted directly to run on the return side of the Conveyor Belt.

Any slowing down of the Drive Motor, Gearbox, Drive Chains, Drive Belts, or the conveyor belt slipping, etc, will result in the conveyor belt and the selected drum/roller slowing down which will be detected by the Motion Sensor.
