Temperature computer control system of a resistance furnace is designed with industry person computer (IPC), temperature input module, PWM output card, solid state relay(SSR) and interrelated circuit.
The resistance and Seebeck voltages used to calculate the ZT and the maximum temperature difference are measured using a testing system composed of a DC pulse generator and a DAQ card.
