Which encoder I have to use to measure a maximum speed of 3 m/min

[weigela]

I have a belt that it is moving with a maximum speed of 3 m/min.

I have to measure this speed and to visualize it on a display.

I want to use an incremental encoder (max. 25000 pulses/rev) with a measuring wheel (200 mm).

I have two questions:
1. I don’t know what encoder to choose, the adequate resolution, how many pulses/revolution
and
2. How I will calculate the speed?

Thank you very much for your support.

1024 PPR (pulses per revolution) is common. The maximum measuring speed will depend on the counter device that you encoder will be connected to. The counter will do the speed calcualtion for you after you enter all the parameters.

is 200mm the diameter or circumference of your measuring wheel?
