Thermocouple wires are essential components in temperature measurement systems, widely used across industries such as manufacturing, HVAC, automotive, aerospace, and scientific research. At Tankii, we specialize in producing high-performance thermocouple wires designed for precision, durability, and reliability in even the most demanding environments.
How Does a Thermocouple Wire Work?
A thermocouple consists of two dissimilar metal wires joined at one end (the "hot" or measuring junction). When this junction is exposed to heat, it generates a small voltage due to the Seebeck effect—a phenomenon where temperature differences between two connected metals produce an electrical potential. This voltage is measured at the other end (the "cold" or reference junction) and converted into a temperature reading.
The key advantage of thermocouples is their ability to measure a wide range of temperatures, from cryogenic conditions up to extreme heat, depending on the wire type.
Types of Thermocouple Wires We Offer
We provide a complete selection of thermocouple wires to suit various industrial and commercial needs:
