ON/OFF process temperature control is recommended for less demanding applications. Systems with two or more heating stages utilize an electronic sequencer (step controller), driven by an analog output PID temperature controller to minimize the amount of load cycling while providing good outlet temperature control.
This fully proportional SCR system with PID temperature control is recommended for industrial heating applications which must accommodate material flow changes and provide the highest degree of accuracy for outlet temperature control.
