I think you are not reading my question carefully.
The example you mention is using to measure the rotational speed of some shaft equipped with gear. gear may have 16, 25 or up-to maximum 100 teeth if you increase the dia.
they use full to measure the rpm of generator which have one gear attached to flywheel, normally magnetic pick up is used there.
hear i am talking to 1024 Pulses encoder (normally used in industrial veritable speed drive.
encoder are very special sensor (these are normally optical ) let me find some detail on net.
yes here they are.
I am not a newbie tell me some thing useful l specific to my question.
thanks your time
