4B Group - Model WDA4 -Belt or Chain Alignment and Motion Monitor

The WDA sensor is designed for use with bucket elevators to detect the buckets in order to measure speed and alignment. It can also detect screw conveyor flights, and ferrous bolts when attached to non-ferrous buckets. A more specialized use of the WDA sensor is for broken/slack chain detection.  

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.  The continues output can be wired normally energized or normally de-energized (please see manual).
