Deflection monitor protects vibratory feeders and conveyors
November 17, 2009
The deflection monitor intelligently tracks the operation of vibratory feeders and conveyors to prevent any damage during operation. The unit can detect abnormal amounts of material on vibratory trays or when some feeder components are failing. The monitor detects changes in tray deflection because material accumulation on the tray surface affects operation. As material accumulates on the tray surface, it adds weight to the tray, affecting performance and possibly damaging the feeder. The monitor alerts, warns or shuts down the feeder so the tray can be cleaned to improve performance and reduce costly downtime. If the tray becomes overloaded, an amplifier senses this and trips a relay to shut down the feeder. Features of this unit include: circuitry pre-set at factory to correspond with feeder amplitude; comparator can be integrated with safety or signaling circuits; sensor cable length available for onsite and remote locations; and NEMA 12 enclosure standard.
