Hello all. I would like to measure the tension on a very thin magnet wire and I have read about people making scales with a galvanometer (voltmeter). Basically, instead of using the meter to measure current, you send current thru the galvanometer and use the needle to exert force on an object. The current required to exert force and the force exerted are supposed to be linear. I was thinking a wheatstone bridge type setup. I am looking to measure in the neighborhood of 5-15 grams. I don't think I'd be able to generate this much force with a regular old analog meter, but I was curious if anyone knows what kind of actuator they use in seismic and polygraph plotters. This would probably be suitable.
I was also looking at strain gages to measure wire tension.
Does anyone have experience in this area? Which route should I go? Does anyone have a better idea?
Any help would be greatly appreciated!...D
