Re: Tachometer

Zach,
McMaster-Carr has several in their catalog. (2-3 pages) A non-contact one would serve you best but these are not cheap devices. $150-$400. Although there was a pocket one that was at the low end of the scale. Unless you are using it for analysis or experimentation it is not a really useful device for our applications. You can only use it when the robot is off the floor so the speed you are measuring is the unloaded speed. When the robot is running you won't be able to follow it around and get a reading especially if the shafts are buried in the body of the robot.
If you are using it for experimentation or demonstration then the cheapest one available will show enough info to be useful.
