Juan Wang, Si Yu Lai · Advanced materials research · 2011
AT89S51 microcontroller based carbon black conductive composite materials resistance-temperature measurement system is designed, which achieves the measurements of resistance and temperature with the help of thermocouple amplifier chip AD595. Describe the hardware and software design, especial the acquisition of temperature and resistance and the display process. The experimental results show that the system can easily and accurately measure the resistance and temperature and the metrical data validate the PTC properties of carbon black conductive composite.
