Chain Conveyor Monitoring

4B has a wide range of sensors for monitoring the various parts of your drag chain conveyor. The most common areas for monitoring include: bearing temperature, speed / motion, level / plug indication and slack/broken chain detection.

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

Chain Conveyor Monitoring

    WDA3 Motion Alignment Sensor

    4B WDA motion alignment sensor
    WDA3 Motion Alignment Sensor

    Non-contacting extended range magnetic proximity sensor, not affected by dust or material build up, used to detect moving ferrous material up to 100mm away from the sensor. The WDA sensor can be used on bucket elevators to measure speed and alignment by sensing either the metal elevator buckets, or the ferrous bolts attached to plastic buckets. A more specialized use for the WDA switch is as a broken/slack chain detector on drag chain conveyors, or as a non-contact speed switch for screw conveyors. The sensor is used in conjunction with a PLC or with 4B's Watchdog™ Elite or A400 Elite control units. Two output signals are provided: one signal is a pulse output, representing each bucket detected: the second signal is a continuous output when moving buckets are detected.

    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.

    Speed Switches

    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.
