        Thermocouple High Temperature Wire


    Thermocouples consist of two distinct metals that provide a means of sensing different levels of temperature in a variety of processes. By combining 2 distinct metals the thermocouple is able to produce a temperature dependent voltage. That specific voltage as long as it’s within the temperature range it's able to interpret accurate temperature measurements. These different forms of thermocouples can be constructed in various ways as some contain flexible wires smaller than human hairs and sheath wires that go up to half an inch in diameter. With this specific variety, no voltage is produced at the thermocouple junction, only in areas of the sensor that are temperature gradient.


    Thermocouple different grades offered:

    Type J Thermocouple (Iron / Constantan): The type J thermocouple is very common, but has a more restricted range than the others reaching temperature limits ranging from -40°C to 760°C. Type J thermocouple is a cost-effective choice that although isn’t as strong as other alternatives, is still continuously reliable.

    Type K Thermocouple (Nickel-Chromium / Nickel-Alumel): The type K is a very common type of thermocouple. The Type K thermocouple is more accurate and reliable than Type J, as the temperature range is much wider. Type K thermocouple is very reliable and has a very wide temperature range of −200°C to +1350°C.

    Type T Thermocouple (Copper / Constantan): The Type T thermocouple is very stable and has a temperature range of −200°C to +350°C. Type T is often used in cryogenics and ultra-low freezers usually located in laboratories, because of its ability to operate in extremely low temperatures.

    Type N Thermocouple (Nicrosil / Nisil): The Type N has very similar accuracy and temperature limits as Type K. The type N thermocouple has overall better performance and better repeatability than Type K, thus making it slightly more expensive for its operating temperature of −270°C to +1300°C.

    Type E Thermocouple (Nickel-Chromium / Constantan): The Type E thermocouple is able to handle stronger signals and higher accuracy than previous Types J or K. This specific grade can be used for testing heating appliance safety, for temperature ranges between −250°C to +740°C and an extremely accurate range between −110°C to +140°C.

    What is the difference between thermocouple wire and extension wire?

    Extension grade wire is a lower grade, cost-effective choice. It is applied by extending from the thermocouple probe to the instrument receiving the signal, where the user can then visually see the results. The Extension wire also has a lower temperature range in which the wire can be used effectively.
