Mike Biddle Posted September 16, 2002 Share Posted September 16, 2002 I need to measure up to 1800 RPM on a small shaft, 40MM dia, prefferably with a small magnet + sensor arrangement, with a small digital readout. The whole thing has to be battery powered a la bike computer. Anybody know where I could source it? Thanks, Mike. Link to comment Share on other sites More sharing options...

Stijn LUYCK 1 Posted September 16, 2002 Share Posted September 16, 2002 How correct does it have to be? Why not use a bike computer ... you could set it up to indicate 180kph for 1800rpm (wheel cicumfence of 1.666m, about an ACB10 I think :-) Link to comment Share on other sites More sharing options...
Mike Biddle Posted September 18, 2002 Author Share Posted September 18, 2002 Thanks for your posts gentlemen, I have now solved the problem by getting a local instrumentation company to make some for me. Mike. Link to comment Share on other sites More sharing options...
