Does anyone have experience that might be helpful. Bill Snead 6W 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. Craig- Hide quoted text - - Show quoted text - Great information Thanks to all Bill Snead 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? Larry 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. |
