Seeking help with thermocouple calculations
Thread Content
As stated in the title, someone reversed the polarity of the nichrome-nickel silicide compensation wire between the thermocouple and the secondary instrument. When the temperature of the electric furnace is controlled at 800°C, with a cold-end temperature of 50°C and a temperature at the instrument terminals of 40°C, the actual measured value is ___°C. How is this calculated? Solve
Let’s find out why it’s 780
How is this calculated?
I encountered one case where the compensation wire was connected in reverse; readings were normal below 50-60 degrees, but they became inaccurate at higher temperatures.
