WDA3 - New alignment sensor for bucket elevators

Product catalog summary

Product Overview
The WDA Sensor is a high power, extended range magnetic proximity sensor designed for non-contact detection of moving ferrous materials up to 75mm away. It is primarily used with bucket elevators to measure speed and alignment, and can also detect screw conveyor flights and ferrous bolts on non-ferrous buckets. A specialized application includes broken or slack chain detection.

Method of Operation
The sensor operates in conjunction with a PLC or 4B's Watchdog™ Elite or A400 Elite control units. It provides two output signals: a pulse output for each detected bucket and a continuous output when moving buckets are detected.

WDA3 - New alignment sensor for bucket elevators-1

Product Information WDA Sensor High Power Extended Range Magnetic Proximity Sensor APPLICATION Non-contacting extended range magnetic proximity sensor, not affected by dust or material build up, used to detect moving ferrous material up to 75mm away from the sensor. METHOD OF OPERATION 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.
