have a three wire thermocouple with the plastic round connector head on the new tanks. we've just used basic johnson/ranco type setups in the past, hollow thermowell and shove the probe down there, etc. haven't used these RTD type setups before so not sure what controllers are good options.
looking for decent quality three wire/RTD and aren't super expensive?
