This thermocouple measurement verified design provides a very simple and accurate method way to implement thermocouple measurement. This design outlines the necessary anti-aliasing filters and biasing resistors to provide sensor diagnostics. This example also provides a novel way of accomplishing cold junction compensation for the system using the onboard temperature sensor on the ADS1118. For thermocouple linearization, the design also provides a very simple algorithm for linear that can be implemented on most microcontrollers.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
