摘要：
Thermocouples have become the most widely used in the field of temperature measurement, due to its wide temperature coverage range, fast response time, simple structure, durability and other characteristics. This paper outlines the working principle of thermocouples, and describes in detail the circuit design of multi-channel thermocouples data acquisition using the precision ADC ADS1258, as well as the data acquisition and processing flow, And how to solve the influence of multiple thermocouples hot-junction grounding in engineering application and the features of using parallel thermocouples for temperature measurement.
