Capacitance Sender converter

My Tracy Crook EM-2 Engine Monitor needs a 0-5 volt input to work properly with the Van's Cap. senders. Blue Mountain sells a set for $140 which a friend of mine used successfully in his 7A, but I'd hope there was someone selling them at a wee bit more reasonable price...does anyone know who that might be?

Thanks for any information.

Build them yourself

If you have the stuff, you won't get a better price than building them yourself (unless someone gives them to you for free). However, having built circuits before, I can say that $140 is not outrageous for a device that is debugged, hardened and ready to bolt into place.

I have a pair of the Dynon units (Beta tester) and they work great!
