How do metal detectors work in food industry?
According to Food Quality Assurance & Inernational Food Safety
All viking food metal detector (Ferrous Non-ferrous.Sus Detection )/
working principle as :
electromagnetic coils are built exactly fixed in a metal detector head frame
The metal detector head center coil is connected to a high-frequency radio transmitter.
Two transmission-receiving coils sit on either side of the center coils of a metal detection
two outer coils are identical and the exact same distance from the center
When two coils of metal detector receive the same signal and produce an identical, balanced output voltage.
when a particle of metal passes through the system,The metal detection will sense it and sent singal to control PCB
The high-frequency field is disturbed beneath one coil, changing the voltage and disrupting the balance.
The output fluxes from zero, producing a signal alerting the system to the presence of metal.
Depending on the specifics of the system, a rejection mechanism is generally activated,
with the ideal result of removal of 100 percent of the metal and a minimum amount of salable product.
