velocity sensor

[cdnrookie 0]

Good morning guys and gals, We are looking for a velocity sensor 4-20ma or 0-10v is fine. It needs to be relatively inexpensive (testing puposes only) and play nicely with a slc 5/03 analog input. Output expected is no more than 500 fpm, more likely under 300 fpm. It is for some venting we have at our plant. Any suggestions? It would be much appreciated. thanks in advance
