thermocouple voltage calculator
Convert thermocouple millivolt readings to temperature or vice versa using standard type-specific reference tables and equations for accurate measurements.
type k thermocouple calculator
A thermocouple detects temperature as a measurable voltage by the Seebeck effect. This calculator interpolates NIST reference data to convert currently measured millivolts into the correct temperature (in Celsius) of a variety of thermocouple types.
Formula & Table Summary:
Formula:
\( V = S \times (T_{hot} - T_{cold}) \)
thermocouple voltage table
The Thermocouple Voltage Calculator allows you to translate thermocouple output voltage (in millivolts) to temperature readings, or temperature in anticipated voltage output. A thermocouple has a low electromotive force (EMF) that is caused because of the Seebeck response which is bound by the variation of temperature between the measuring junction and the reference junction. Standardized polynomial equations or the NIST reference tables are used in the calculator at different thermocouple types (e.g. Type K, J, T, E). Specifying the type of thermocouple and entering a voltage value or a temperature value goes a long way to obtaining an accurate conversion, which allows it to be useful in industrial applications, HVAC, lab equipment, and electronics-based work.
