Using microcomputer PC 8001, A/D and D/A converter, a continuous voltage feedback control system has been developed for accurate and flexible temperature control.
Control parameters can be changed during running, and the controlled ADC and DAC data are recorded in RAM of PC 8001. And Z80 assembly language is used for software programming.
8-bit A/D converter is used and the developed temperature control system has been runned with the accuracy ±0.2℃ for the setting temperature, on condition that the experiments have been done under a steady supplying voltage.
