Sensor system keeps conveyors in sync

A 4B Braime Elevator Components product story
Edited by the Engineeringtalk editorial team Jul 5, 2006

The AB400 Elite from 4B uses an electronic microprocessor control unit and up to four magnetic alignment sensors to monitor the alignment of the belts of two separate bucket elevators/conveyors.

The AB400 Elite from 4B uses an electronic microprocessor control unit and up to four magnetic alignment sensors to monitor the alignment of the belts of two separate bucket elevators/conveyors.

Alternatively the four sensors can monitor the top and bottom belt alignment in a single bucket elevator.

For alignment sensing, the two probes, which are mounted on the elevator, will generate one pulse for each metallic bucket or bolt.

If the elevator belt becomes misaligned, one of the probes will fail to detect the buckets or bolts, and the control will then cause the alarm relay to energise and, after a delay, the stop relay will de-energise.

Two separate alarm relays and two separate stop relays are provided.

A self-test feature allows the control unit to check itself for correct function.

An option for RS485 comms allows remote monitoring by PLC or PC.
