Stainless Steel Detection

[Oseania]

I read that most PI metal detectors don't detect some stainless steel grades because the conductivity is so low that the eddy currents dissipate before by the time pulse delay has ended and the sampling begins. Is it possible to detect stainless steel with VLF metal detectors and has anyone tried it?

I believe stainless steel is hard to detect with VLF machines too. It is a problem for the food industry, as it is one of the most likely contaminants in the processing chain. Search the web for articles about metal detecting in the food manufacturing process.
