Product Application - Belt Conveyor


4B has a wide range of sensors for monitoring the various parts of your belt conveyor. The most


common areas for monitoring include: bearing temperature, speed / motion, belt alignment and


level / plug indication .


All of 4B's sensors can be connected to our hazard monitoring systems.


4B also has has an entire line of material handling products, including - conveyor belting.
