Conveyor Components Co. has introduced the Mag-Neat-O, a self-contained motion controller that magnetically couples to the end shaft of a tail pulley and indicates when a conveyor belt has slowed or quit moving altogether. The pulse output of the Mag-Neat-O can be wired into a PLC or DCS, which can determine under speed, overspeed or zero speed of the conveyor.
The controller can shut down rotating equipment before severe damage is encountered and provides protection for interlocked conveyor belts, especially if one of the belts fails due to overloading or quits due to conveyor belt tearing/separation. The standard construction is a chemical and impact-resistant polymer material, with stainless steel internal parts.
With the Mag-Neat-O, no drilling or tapping of the tail pulley shaft is required, as the unit is held in place with a strong magnetic connector on any non-driven pulley shaft. This compact design will fit in most places on a conveyer system.
Optionally, it can be connected to the model RMS-G (using the 2-wire sensor) or MSD-800 controller (using the 3-wire sensor), which supplies relay outputs to control up to two separate circuits, one for machinery shutdown and one for an alarm.
