How to use the thermocouple voltage calculator
Estimate the voltage a thermocouple produces for a given temperature difference. Enter seebeck coefficient, temperature difference in the fields above; the thermocouple voltage is computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “thermocouple output”, “Seebeck voltage”, “K-type thermocouple voltage”, “calculate thermocouple voltage”, “find thermocouple voltage”.
Formula
Variables
- S — Seebeck coefficient (µV/K)
- dT — Temperature difference (K)
Worked example
With seebeck coefficient = 41 µV/K, temperature difference = 100 K, the calculator gives thermocouple voltage ≈ 4.1 mV.
Frequently asked questions
What is the thermocouple voltage calculator used for?
Estimate the voltage a thermocouple produces for a given temperature difference. It helps with questions such as “thermocouple output”, “Seebeck voltage”, “K-type thermocouple voltage”.
What is the formula for the thermocouple voltage calculation?
Thermocouple voltage (mV) = S × dT / 1000. Here S is seebeck coefficient (µV/K), dT is temperature difference (K).
What inputs do I need for the thermocouple voltage calculator?
You need seebeck coefficient in µV/K, temperature difference in K. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the thermocouple voltage calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the thermocouple voltage result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
