We cannot control through thermocouple/RTD, they are only
measuring elements,which is connected to temperature
controller which as set value for which point it has to
control temperature (PID/Relay logic control)..Meanwhile
Temperature transemeter is used to convert mv/ohm to anolog
signal(4--20 ma)...we have to refer ohms/mv to degree Celsius
