Hi guys, this is my first post. I'm building a wind generator, and would like to monitor the RPM so I can compare it to wind speed and output. I tinker with electronics but am much more mechanically competent, so looking for some advice on the right way to do it.
Here is the generator I'm using- **broken link removed**
Here is the tach that I plan to use (already have one)- http://www.veeder-rootcounters.com/uploadedFiles/Downloads/MaxJrTachMan.pdf
I was thinking that it would be easiest to monitor 2 of the 3 legs before it is rectified to DC and calibrate the tach to read RPM. So, I think I need a circuit that can turn the variable voltage frequency into a pulse that is compatible with the tach. Voltage could potentially get over 100 VAC if the DC breaker trips in a storm and the generator has no load.
The simpler the better...any advice would be appreciated!
