Flexible, Low Power, 4-Channel Thermocouple System with Arduino-Compatible Analog Interface

Analog Devices Inc.

The circuit is a flexible, integrated, 4-channel thermocouple measurement system based on the Arduino compatible EVAL-ADICUP360 platform, which contains the ADuCM360 low power, precision analog microcontroller. The ADuCM360 has an ARM Cortex™-M3 processor core, a number of peripherals, and also precision analog functions including a dual, 24-bit, Σ-Δ analog-to-digital converter (ADC); multiplexer; programmable gain amplifier (PGA); and voltage reference. The circuit 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.
