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
