A type K thermocouple with a 0C reference is used to monitor

A type K thermocouple with a 0°C reference is used to monitor an oven temperature at 300°C. What voltage would be expected from the thermocouple?

Solution

Type K Thermocouple (Nickel-Chromium / Nickel-Alumel): The type K is the most common type of thermocouple. It’s inexpensive, accurate, reliable, and has a wide temperature range. The type K is commonly found in nuclear applications because of its relative radiation hardness. Maximum continuous temperature is around 1,100C.

for the type k thermocouple with reference voltage at 0celsius and hot junction at 300 celsius the thermoelectric voltage is within the range 12.209mV to 12.626mV
