| I got caught here. I do sometimes put the sprocket in a lathe and knock the tops of the teeth off. For some reason a Hall Effect Sensor seems to work better for me on sprockets. http://www.redlion.net/products/groups/archive/hess/docs/11023.pdf This one seems to be weather and crud proof. I have some over 10 years old, and have never had a failure. You should put the sensor on the idler with a belt, but not with a chain conveyor. I did that once without thinking first and got a jumpy readout. The chordal motion of the chain causes a problem with the idler.
My first choice for a conveyor speed sensor is to get it built into the motor. http://hydraulics.eaton.com/products/pdfs/04-106.pdf It is a clean installation, comes with a Weatherpac connector, and works really well on 12 volt systems. With a 2000 series Char-Lynn motor and a Rawson gearbox you get 180 pluses/rev. | |

What parts do I need to make my litter/lime buggy do VR?
