The A400 Elite Trackswitch belt misalignment monitor uses 4B WDA or BAP magnetic proximity sensors to monitor the alignment of the belt in bucket elevators. Each control unit incorporates two independent monitoring circuits for early detection of belt misalignment on one or two bucket elevators. The 4B magnetic reluctance sensors operate in pairs to detect the position of steel bolt heads or steel buckets as they pass through the sensor's adjustable magnetic field. Nuisance / false alarms are tuned out by setting a tolerance window on each sensor which allows for normal belt travel. Status LEDs on the control unit indicate the alignment condition of the belts on the elevators, while internal relay contacts provide alarm and automatic shutdown of the elevator when hazardous misalignment conditions are detected.

Sensors
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.
BAP Misalignment Sensor
The BAP detects moving ferrous material and is designed for use with bucket elevators to detect belt misalignment condition. It can also detect ferrous bolts where plastic or 316 stainless buckets are used . The sensor is used in conjunction with a PLC or with a Watchdog or A400 Elite control unit.

Hazard Monitoring Design Service
Hazard Monitoring Design Service
Preventative maintenance can help reduce the risk of equipment failure and consequent downtimes. When it comes to monitoring your bucket elevators and belt conveyors, 4B can recommend you the ideal combination of sensors and monitoring systems to suit your requirements and budget.
4B provides an extensive range of their own ATEX / IECEx / CSA approved hazard monitoring systems, misalignment switches and bearing temperature monitors and level controls. We can offer you anything from a replacement sensor to a fully integrated hazard monitoring system which can be operated either as a stand-alone system or connected to your PLC.
And if you do not want to install hazard monitoring sensors on every piece of equipment in your plant straightaway, we can offer you a scalable solution starting with carefully chosen equipment and systems that can be expanded at a later date to encompass other machines in the plant.
We can also offer you an installation service, and we do provide a competent after-sales technical service to help you overcome any technical problems with your monitoring equipment.
To get a recommendation from our engineers, please fill in the electronics questionnaire below. Please fill this form in as accurately as possible to allow us to deal with your enquiry more effectively.
