conveyor belt wikipedia. 201985the belt sway switch will stop the conveyor if the belt starts losing its alignment along the structure the speed switch will stop the belt if the switch is not registering that the belt is running at the required speed the belt rip switch will stop the belt when there is a cut or a flap indiing that the belt is in danger of further damage
i'm trying to detect if a conveyor belt is really moving or not. at first i thought of using a rotation sensor (inductive proximity sensor) on the pulley (or drum don't know how you call it) to detect if it's moving. i cannot put it on the motor itself because if the chain breaks the
2011522&ensp·&enspthe choice of scoop type fluid couplings or slip ring motors is likely to lead to the use of smaller motors with safety and possible savings on switch gear maintenance. 4.3 other drive methods: where a variable conveying rate is required d.c. drives can be used
