Misalignment Monitors for Belt Conveyors
Misaligned conveyor belts can not only lead to spillage and unscheduled downtimes; they can also damage a conveyor. Misalignment sensors can detect belt misalignment and shut down the conveyor if necessary.
4B offers a range of contacting / mechanical and non-contacting sensors to detect misalignment on belt conveyors as well as compatible hazard monitoring systems.
