Hello everyone,
Sorry for my enquiry if it's too simple problem for you, anyway I am new to LabView. I want to measure rpm of a shaft. Let me describe the setup. I have attached two magnets on either side of the shaft and placed a hall effect sensor near by. In each revolution when north pole passes I get positive volt and when south pole passes it reduced to 0 volt. So i get square signal and each consecutive peak indicates one revolution. Now the thing is that I want to count the peaks lets say 10 peaks (or 10 rev) and the time from 1st peak to 10th peak. then I want to calculate the rpm.
