Quick Details
What is Thermocouple Wire?
The two wires that make up the thermocouple pair are made from a range of different alloys and metals and have been standardised by both international and national bodies.
K Type Thermocouples
Thermocouples are temperature sensors that work based on the principle of the Seebeck effect, discovered by Thomas Johann Seebeck in 1821. The Seebeck effect states that when two different metals are joined at two junctions, and there is a temperature difference between the junctions, an electromotive force (EMF) or voltage is generated across the metal junctions.
Type K
thermocouple is one of the most popular types of thermocouple.
K
thermocouple consists of a positive Nickel/Chromium alloy leg and a negative Nickel/Aluminium leg.
K
thermocouple can be used across a wide temperature range (from -200°C to 1250°C), making it suitable for many applications in a variety of industries.
K
thermocouple is a much more affordable option than the Platinum based Type R and Type S thermocouples which can be used at higher temperatures.
K type thermocouple wire is commonly used for temperature measurement in high-temperature environments, such as furnace temperature, heat treatment, and melting processes.
Types of Thermocouples
What differentiates one thermocouple from another is the metals in its two wires: the positive leg and the negative leg. Because each thermocouple type has a different pairing, they differ in temperature limits, process conditions (inert, oxidizing, reducing atmospheres, heavy vibration), and so on.
