Folks,

I just finished up a  vertical  sensor with an AS-1 like suspension.
After looking at the AS-1 pictures, and reading about it, I cannot see any
information about the damping of the suspension spring.

Does any one have one of these?  What am I missing because the spring being
used here while allow in for almost 4 sec. period, once excited rings for a
long time.

It seems that a magnet mounted in the center of the spring, and an aluminum
plate is very effective in reducing these.

Any ideas?

My spring is ferrous, and I would like to get a non ferrous replacement.
