Need COTS Analog Speed Signal from Encoder

[Wes_Ramm1]

Hello everyone, need some shopping help. 

I have a customer who wants to get a scaled analog output corresponding to rotational speed from an encoder instead of doing traditional freq measurements.  We want a stand alone package that does the frequency measurement on board and just puts out a scaled analog output.

Need < 100 mS latency and ability to resolve 5 rpm to 1000 rpm.  Just don't know where to go to buy one.

Anyone know of such a device?

Thanks

One example of many manufacturers of frequency to voltage converters:

Look at the detailed specs to make sure the unit's input voltage range is compatible with the encoder along with the response time.

Look at that, Din rail mounted, etc.  Way to go AK2DM!

I thought you could only get Freq-Voltage converters on the chip level.

Glad to be of assistance.

I have used several of their converters and isolators to get me out of ground loop and signal incompatibilites and have been pleased with their support and performance.

Perfect.  Now I need to find a source in the UK, and I am all set!
