What is a type K Thermocouple?

K%20Thermocouple

All Thermocouple types work on the same basis, they consist of two wire legs made from dissimilar metals (Nickel-Chromium / Nickel-Alumel in type K) which are fixed together at one end, creating a junction (Fig 1). When this junction experiences a change in temperature a voltage is created, this voltage can then be measured and referenced back to the temperature.
