| Abstract: | The thermoelectric-potential determining system of E-type thermocouple based on MCU is introduced in this paper. The cold end temperature is measured by an integrated digital temperature sensor and the hot end temperature is measured by an E-type thermocouple.After being pre-amplified and A/D transformed,the signals are transferred to the MCU and processed by it.Finally the thermoelectric potential and temperature are displayed on the digital displayer.The temperature measuring system has many advantages,su... |
