Measuring Angular Velocity and Position

Other Hardware Sensors
1

Hi,

I'm working on a project and I need to be able to measure the angular velocity and angular position of a beam that pivots at its end. It wont make a full revolution, only about 135deg range of motion. I'm not sure what sensor to use for this. An incremental rotary encoder seems like my best option so far, but I don't really have any experience with sensors like this.

Is it possible to derive the angular velocity of the beam using a single turn rotary potentiometer?

Is there some type of sensor that I am over looking that would be better suited for this application?

Thanks in advance

Rotary encoder is ideal for the job. Simply time the space between pulses and it's inversely proportional to the angular velocity.
