I have a device that varies from 19 to 63 ohms and need to read it and determine its present value. It appears that a Wheatstone Bridge would allow a 5v input with the output used by an A to D converter. My problem is that I am not up on the math needed to calculate the appropriate values of the ot…

Wheatstone Bridge Values Needed

It doesn't have to swing from zero to 5 volts.

If someone familiar with this could give me some R values I would greatly appreciate it.

Thanks in advance.
