A bit off topic, but I have an old heat trace controller where they used the power cable to get the rtd reading. They have lil pc board at the rtd the converts the signal so it can be carried on the 120vac ckt back to the panel. Naturally they are no longer in business and we are looking at replacing the panel. I hate to run new RTD wires for a standard control. Does any know if some one make a converter to impose a rtd reading over the 120 vac ckt? Guess I could wireless, but I hate to go down that path if not needed.
