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.
Detects level or plug situations for bulk granular solids or liquids in tanks, bins, or silos and can be used as a plug or choke detector in chutes, conveyors and elevator legs.
Overheated bearings are one of the main risk factors for dust explosions in bucket elevators and need to be closely monitored.
4B offers a range of Atex, CSA and IECEx certified bearing temperature sensors and compatible monitoring systems.
4B's line of speed switches includes: proximity, inductive, zero speed, stop motion and rotech encoders to monitor dangerous belt slip, underspeed or stop conditions on conveyors, bucket elevators and any other shaft driven machinery. Our non-contacting sensors can be used to detect screw conveyor flights, elevator bucket bolts and other moving ferrous targets. Speed switches can be connected to a PLC or to one of 4B’s hazard monitoring systems to provide alarm and/or shutdown of your machinery when dangerous conditions are detected.
