Does anyone have experience that might be helpful.

You can buy strain gauge based electronic tension systems with hand
held readout units either wired or wireless. They are sometimes
called "crane scales" or "dynomometers". Just Google "tension load
cell". You'll want a 0-2000 Lbf unit.

There are also clevis attached USB tension load cells which plug into
your laptop which come with appropriate software. The USB units are
nice since they are powered by the USB bus - just plug and play.

There are others too. I've been looking for a similar inline load cell
and will probably purchase fromhttp://www.futek.com/. I don't have
any relation to the company, but have been looking for a while and
their offerings appear to be pretty solid.

Great information

Thanks to all

Just out of curiosity, where is one of the items placed in the system???

They look like a big "S". *Where do you attach what?

There will be threaded holes in the top and bottom of the "S" for I-
Bolts. *The "S-Beam" shape is to maximize the deformation (strain)
under load so the thin film strain gauges have a larger signal to work
with. * It's a good idea to enclose the load cell in a housing to
protect it.

eye bolts?
