Product Application - Screw Conveyor


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


common areas for monitoring include: bearing temperature, speed / motion, level / plug indication and


door / gate position.


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