Hi All,  I am moving right along on the small vertical spring sensor I =
am building.  At this point I would like to ask two questions;

1.  I have made an adjustable magnetic damper, which I can slide in and =
out to increase or decrease the effect.  Chris, gave me a very good =
example of how to adjust the damper on the Horz Lehman, I finished a few =
months ago.  It was something like, "move the arm 10mm and release it, =
it should move past center and extend 5mm past center, it then should =
return to center and stop;"   Would it be the same for a vertical spring =
sensor?

2.  The coil measures 847 ohms.  If I were to use a resistor to act as a =
damper, what would the ohms value be for the resistor?
     Is there a formula?

Thanks, Ted







Hi All,  I am moving right along = on the small=20 vertical spring sensor I am building.  At this point I would like = to ask=20 two questions;
 
1.  I have made an adjustable = magnetic damper,=20 which I can slide in and out to increase or decrease the effect.  = Chris,=20 gave me a very good example of how to adjust the damper on the Horz = Lehman, I=20 finished a few months ago.  It was something like, "move the arm = 10mm and=20 release it, it should move past center and extend 5mm past center, it = then=20 should return to center and stop;"   Would it be the same for = a=20 vertical spring sensor?
 
2.  The coil measures 847 = ohms.  If I=20 were to use a resistor to act as a damper, what would the ohms value be = for the=20 resistor?
     Is there a=20 formula?
 
Thanks, Ted
