Description:
Thermocouples are the simplest form of temperature sensors. Thermocouples are normally:
  • Very inexpensive
  • Easily manufactured
  • Effective
over a wide range of temperatures Thermocouples come in many different types to cover nearly every possible temperature application. In Application Note AN684, thermocouple basics are covered along with some circuits to measure them. This Application Note begins where AN684 leaves off and describes methods of obtaining good accuracy with minimal analog circuitry. Also covered in this Application Note are:
  • Different linearization techniques
  • Cold junction compensation
  • Diagnostics
