Type Of Sensor Selection

04/03/2017 6:08 AM

Hello everyone

I am working in a food company.powder is packed by us in aluminium foil paper. I want to install a metal sensor on the pouch to sense the metal but due to aluminium foil it sense the aluminium foil aswell. Can anyone have any suggestion.

Thanks

What type of metal is it that you're trying to sense, and how thick is it? does it cover the face of the sensor when in position? What sensor are you using (manufacturer and part number)?

I'm wondering if this doesn't even require machine X-vision. Depending on the shape, density, and position, possibly just an X-ray threshold detector will do, if the OP is simply looking to see if the part is present or not.

Use ultrasound/ultrasonic sensor, may be where EM sensing is not possible due to interference.

What is an 'untrasonic' sensor?

Ultrasonic, rather. He may analyse reflected sound wavelengths at certain bandwidths larger than the powder and less than the packaging.

That should work.

Maybe you could switch from foil packs to a safer cheaper alternative....?

Why not do the sensing before the packing?

Because the packing is the potential polluter...
