Electromagnetic Noise

MANAGING ELECTROMAGNETIC INTERFERENCE IN FOOD METAL DETECTION

EMI/RFI noise occurs when different electrically powered machines and peripheral equipment operating in close proximity to each other are not shielded or filtered correctly.

Noise is a common occupational hazard in food processing factories, from vibrating panels to mechanical rotors, stators, fans, conveyors, pumps, compressors, palletizers, and fork lifts. Additionally, some less audible disturbances can impair the performance of highly sensitive metal detection equipment, the most overlooked being electromagnetic interference (EMI/RFI) noise generated by ground loops and electric motor drives. 

Eric Garr, regional sales manager at Fortress Technology examines the cause and effect of these disturbances and the measures that can be implemented to reduce noise interference.
