Hi Guys,
I am finishing up the design and
fabrication of my variable length EDDIE intake and need some assistance. I
want to use a voltmeter (or LEDs) to indicate the postion of the manifold.
The simplist approach would appear to have a linear resistor attached such that
its arm is moved as the manifold moves thereby changing the resistance
indicating distance.
I've done a lot of Web surfing and found a number
of linear postion potentiometers. The problem is they cost more than I
have invested in the manifold. Regular audio linear potentiometers do not
have the mechanical range I need. I need a position indictor that has at
least 5 1/2 - 6" of travel. Anyone have any ideal where something
reasonably priced might be found.
If you know of a retail catalog that have
such things I'd appreciate a pointer. I can find plenty of Linear Postion
Potentiometers - but they cost in the hunderds of $$. Need something much
cheaper.
I know I could devise a 3:1 lever ratio or some
such thing and use one of the cheap (but mechanically range restricted) linear
potentiometers for audio circuits, but would rather not.
Thanks
