: I´m searching for any knid of info for build a conductivity transmitter, such schematics, advices, theory of operation, etc.
: The goal is to get a 4..20mA signal proportional to the conductivity of a solution, and to use this signal to control a process in a boiler.
: Any info would be very thanked.
: Thanks in advance,

There are many sources of products and help for conductivity measurements, but give a look at http://www.topac.com/ for a start.
