Hall Effect

Hi,

Being a novice at electronics maybe there is someone on the list that could explaine why the following cannot be done.

Take a 1/4" internal diameter tube of aluminum and mill a 3/16" slot down it then fill itwith high grade ball-bearings. You have just made a very accurate scale. If you then move a Hall-Effect device alone it lenth what kind of signel do you get, is it analog or digital. If the former could the signel then be feed into an analog/digital converter the rest is easy.

Regards,

Terry
