Conversion of Thermocouple Voltageto TemperatureGerald Recktenwald February 27, 2020 AbstractThis article provides a practical introduction to the Conversion of ther-mocouple Voltage to Temperature . Beginning with a description of theSeebeck effect, the basic equations relating EMF and Temperature arepresented. A few of the more practical Thermocouple circuits are ana-lyzed, Temperature measurement with a basic ice-point reference circuitis described, and computational formulas for data reduction are of a zone box with a floating reference junction Temperature is OverviewThermocouples are inexpensive and versatile devices for measuring can be purchased in many different prefabricated basic laboratory work, thermocouples can be easily fabricated from bulkthermocouple wire.
conductor wire. On the other hand, the Seebeck coe cient of a given material can be e ected by oxidation or reduction of the conductor material, or by plastic strain of the conductor. In general, the Seebeck coe cient is a function of temperature. To develop a more precise and versatile relationship than Equation (1), consider an exper-iment ...
