If 20 mV shows 750 degrees Fahrenheit and 50 mV shows 1250 degrees Fahrenheit then 35 mV will show 1000 degrees Fahrenheit.

How is thermocouple WORKING?
A thermocouple is a thermometer made by using two wires of different metals in a circuit. Two junctions are then formed between the different metals-- one of which is joined to the object having the temperature to be measured and the other is joined to an object having a fixed temperature. An measurable voltage proportional to the temperature difference is generated in the loop.
What is the function of thermocouple?
The thermocouple does not actually measure temperature, but the temperature difference between two points. If the temperature at one point is known (reference junction) then the temperature of the other point (sensing junction) can be calculated.
Can copper wire be used for thermocouple extention?
No. A thermocouple is made from two dissimilar wires. At the junction of these two wires, an electrical signal is generated that is measured in millivolts. If you insert another type of wire, such as copper, then you have introduced another electrical junction. Your signal will be (millivolt from junction 1 + millivolt from junction 2). <><><> Maybe. A thermocouple measures the temperature difference between the sensing junction (where the two different metal wires meet) and the other end of the wire, the reference junction. If you extend a thermocouple with copper wire, you will measure the temperature difference between the junction and the location where the copper extension is spliced on. If the copper splice is the same temperature as the reference junction, or if you can measure the temperature at the splice, then it will be fine. In general, it is better to run the thermocouple wire to the reference junction.
How does a thermocouple work on a gas boiler?
A Thermocouple is simply a temperature-sensor consisting of a junction between two metals, where the tiny voltage between them varies with temperature. This change in voltage can be detected and acted upon by the electronics controlling such things as boilers.
What is the difference between thermocouple and RTD?
A thermocouple measures temperature difference between two points, producing a tiny voltage corresponding to the difference in temperature. To measure temperature with a thermocouple, you need to know the temperature of one junction and calculate the difference from the table or equation for the type of t/c used. An RTD changes resistance in response to temperature--to measure temperature with an RTD you measure its resistance (usually by putting a known voltage across it and measuring the current).
What temperature is between 8 Fahrenheit and -12 Fahrenheit?
The halfway point temperature is -4 F.
What is the temperature difference between 74 Fahrenheit then 63 Fahrenheit?
11 degrees Fahrenheit
Is thermocouple a temperature measuring device?
No, by itself a thermocouple can only measure temperature difference between two points (junctions) in a circuit. To use a thermocouple as a temperature sensor, you must know the temperature of one junction by some other means. Often an additional temperature sensor is used. However, in some applications temperature difference is enough. For example, in gas appliances a thermocouple detects presence of a flame because the flame is much hotter than room temperature-- you don't need to actually measure the flame temperature. ====================== Yes, it is. If you look up "thermocouple" in Wikipedia, you will find a very detailed explanation of how and why they work.
What is the temperature difference between -6 Fahrenheit and 74 Fahrenheit?

Can a mercury thermometer be used to measure temperature between 500 and 600?
No, you need another type of device as a thermocouple.
