General Description

In thermocouple temperature measurement, the thermocouple temperature is calculated based on the measured thermo-emf voltage. The voltage to temperature conversion is characterized by the National Institute of Standards and Technology (NIST), and NIST provides tables and polynomial coefficients for thermo-emf to temperature conversion. The NIST tables and polynomial coefficients can be found in the following link:

Thermocouple temperature measurement also involves measuring the thermocouple reference junction temperature and converting it into a voltage. The Thermocouple Calculator component simplifies the thermocouple temperature measurement process by providing APIs for thermo-emf to temperature conversion and vice versa for all thermocouple types mentioned above, using polynomials generated at compile time. The thermocouple component evaluates the polynomial in an efficient way to reduce computation time.
