What’s a thermocouple?
A thermocouple consists of two dissimilar metal wires joined at one end, known as the measurement junction. When the measurement junction is heated or cooled, it generates a thermoelectric voltage that can be correlated to temperature. The other end, where the wires are not joined, is connected to the instrumentation that reads this voltage. The difference in temperature between the measurement junction and the reference point (usually at the instrument) is used to determine the actual temperature at the measurement junction.
Tankii Available types:
One of the factors to consider when choosing metals used in a thermocouple is the temperature range of the application. Common thermocouple types include:
These types are used for high-temperature applications, offering stability and resistance to oxidation in temperatures up to +1700°C for Type S and R, and up to +1800°C for Type B.
Positive Lead for Type S and R: Platinum-Rhodium alloy (Type S has 10% Rhodium, Type R has 13% Rhodium)
Negative Lead for Type S and R: Platinum
Positive Lead for Type B: Platinum-30% Rhodium
Negative Lead for Type B: Platinum-6% Rhodium
