Screw Conveyor Monitoring

4B has an extensive range of CSA / ATEX / CE / IECEx / GOST-R approved hazard monitoring systems specifically designed for bucket elevators and conveyors in dust hazard environments. As an industry leader in developing high quality, innovative, and dependable electronic components, 4B can recommend the ideal system to suit your requirements and budget.

4B inductive proximity sensors are designed to detect shaft speed, shaft position, gate position or object presence. No contact is made between the sensor and the target being monitored. 

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.
