A400 Elite Trackswitch
Belt Alignment Monitor for Bucket Elevators

The A400 Elite Trackswitch belt misalignment monitor uses 4B WDA 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 WDA 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.

			WDA Motion Alignment Sensor The WDA is a non-contacting extended range magnetic proximity sensor, not affected by dust or material build up, used to detect moving ferrous material up to 3 inches away from the sensor. Used for detecting alignment on belt bucket elevators, or slack / broken chain on drag chain conveyors. More Info

	Preventative maintenance can help reduce the risk of equipment failure and consequent downtime. When it comes to
	monitoring your bucket elevators and conveyors, 4B can recommend the ideal combination of sensors and monitoring
	systems to suit your requirements and budget.

	4B has an extensive range of CSA / ATEX / IECEx approved hazard monitoring systems, misalignment switches,
	bearing temperature monitors and level controls. 4B can offer you anything from a replacement sensor, to a fully
	integrated hazard monitoring system which can be operated as a stand-alone device 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, 4B
	can offer you a scalable solution that can be expanded as your needs grow.
