rpm sensor for 60 tooth steel wheel with weird f/v converter

rpm sensor for 60 tooth steel wheel with weird f/v converter

(OP)
I'm a retired calibration & controls guy.
I have a client with a testing machine that uses a 60 tooth wheel for rpm.
The sensor (magnetic? hall effect? prox?) was lost. Of course, no records.
The sensor's output was sent to an f/v converter - Analog Decives, Inc. 5B45-05.
Spec. pdf is at:
http://www.analog.com/static/imported-files/data_sheets/5B45_46.pdf
Tried standard NPN & PNP prox's - no good.
I would like to find a hall effect or magnetic sensor that would work with the existing 5B45 f/v.
Alternatively, I could replace the f/v converter with another model that accepts a standard hall effect sensor.
I need to have 0-5vdc=0-10,000rpm output from the replacement.

I can even go to a photo sensor, if you think it best. There's a 6-black/6-white disk I can use for that.
Thanks for your help.

RE: rpm sensor for 60 tooth steel wheel with weird f/v converter

It looks like it is designed to take almost any standard frequency input. It simply has to be configured and wired correctly for the given input. What did you try that did not work? A 60 tooth wheel has to turn at 10,000 to get a 5v output.
