What signal conditioning is required for thermocouple inputs?

Thermocouple signal conditioning requirements: Cold junction compensation (CJC) - corrects for reference junction temperature using RTD or thermistor at terminal block. Amplification - TC output is small (40-60 microV/degree C typical), requires high-gain amplifier. Linearization - TC response is non-linear, requires lookup table or polynomial correction. Filtering - removes noise while preserving slow-changing temperature signal. Burnout detection - identifies open thermocouple. These functions are typically integrated in TC transmitters or input modules.
