Multi-Channel Temperature Sensor

Overview

Aiming at the high and low temperature test requirements of cars before being sent on roads, this paper designs and implements a multi-channel thermocouple temperature measurement system based on FPGA. The system adopts thermocouple as temperature sensor, and K Type is used as thermocouple cold junction temperature compensation, which solves the problem of thermocouple cold junction compensation better. The front end adopts MAX11200, a 24-bit analog-to-digital converter with low noise, multi-channel and low power consumption, to amplify and A/D convert the signal at measuring junction of thermocouple. The control core is a field programmable logic gate array FPGA, which can better solve the problem of parallel processing of multi-channel temperature signals. At the same time, it uses the transposition method of the thermocouple standard graduation table, the interpolation look-up table algorithm and the cold junction compensation reverse look-up table algorithm, which is effective. The temperature measurement accuracy of each channel is improved. The experimental results show that the system can be connected to 8 K-type thermocouple sensors, the measurement range can reach -200℃~220℃ (73.15K~493.15K), and the relative error is less than ±0.3%F.S.
