Analog Devices 4-Channel Thermocouple | EVAL-CN0391-ARDZ
Flexible, Low Power, 4-Channel Thermocouple System with Arduino-Compatible Digital Interface
This circuit is a flexible, integrated, 4-channel thermocouple measurement system based on the AD7124-8 low power, low noise, precision 24-bit, Σ-Δ analog-to-digital converter (ADC). It can process up to four independent thermocouple channels, and the software linearization algorithms support eight different types of thermocouples (B, E, J, K, N, R, S, and T). The four thermocouples can be connected in any combination, and resistance temperature detectors (RTDs) on each thermocouple channel provide cold junction compensation (CJC). No extra compensation is needed. Thermocouple measurements using this system cover the full operating range of the various types of thermocouples.
