Pneumatic tubes capabilities

Hi,

I have recently developed a pneumatic gizmo to remotely act on my train
track points, which is working quite nicely. The thing is, I don't know *how
far apart* can I place the compressor so that the loss of charge in the
tubes isn't too big. Has anyone tested this?
And another question, related: to remotely act on the points, I need to have
the pneu-switches *far* from the points (doh!). But by doing that, instead
of having one *long* tube from the compressor to the pneu-switch, I'll have
two from the pneu-switch to the pneumatic cylinder. Does that mean the
design will work less efficiently, or is the difference neglectible?

TIA,


Pedro

(...) From my experience, you can have really long tubes (10~20 feet, or more) and not have significant losses due to friction. What you should be concerned with is the volume of the tubes. Basically, if you have a lot of long tubes, your system (...) (22 years ago, 6-Sep-02, to lugnet.technic)

It's a pity there isn't a remote-control pneumatic switch you could connect up to Mindstorms or a similar system. I would *love* to be able to remotely control switches, this would solve your problem somewhat by drastically cutting (figuratively (...) (22 years ago, 7-Sep-02, to lugnet.technic)
