I have a need for a temperature controller which will use a thermocouple as the setpoint and a different thermocouple as feedback.
I have 2 heaters and I want the second one to follow the temperature of the first. I want to use a TC in the first one to determine the setpoint for the controller of the second one.
I would prefer a discrete controller although PLC may be an option if necessary. I have a few vendors working on it but I'd appreciate any input regarding this type of controller, it seems none of the standard controllers have this ability.
