Thermocouple Wire

Thermocouple wire is the essential conductor used to build or extend thermocouples and transmit accurate temperature readings. IOThrifty offers premium thermocouple wire in Types K, J and T, all in measurement-grade construction with Special Limits of Error (SLE) accuracy. Our wire is designed for long-lasting insulation and dependable performance in high-temperature and industrial applications.

Why Use Thermocouple Wire
Thermocouple wire consists of two dissimilar metal conductors matched to specific thermocouple types. When joined at a hot junction, these paired metals produce a millivolt signal that corresponds to temperature, making wire quality and composition critical for accurate measurement. Measurement-grade wire ensures tighter accuracy tolerances than standard extension wire, which helps maintain temperature precision across your sensor system.(/sourced by product page content and thermocouple principles/)

Types of Thermocouple Wire We Offer
IOThrifty stocks thermocouple wire for the most commonly used thermocouple calibrations, providing flexibility for sensor fabrication and installation:

• Type K measurement grade wire ideal for general-purpose, wide-range temperature measurement.

• Type J measurement grade wire suited for environments where moisture is minimal and reliable service is needed.

• Type T measurement grade wire excellent for cryogenic or low-temperature applications with stable performance.
  All of our wire is offered on spools ranging from shorter lengths to 1,000 feet, allowing you to cut the exact amount you need for your project. Wire is manufactured with high-temperature insulation such as PFA or glass to handle demanding conditions.

Applications
Thermocouple wire is used whenever custom sensor assembly or wiring extension is required.

• Fabricating thermocouple probes, sensor leads and assemblies to exact lengths

• Extending thermocouple connections between sensors and measurement instruments

• Replacing worn or damaged sensor leads in industrial environments

• Wiring temperature sensing networks for process control, data logging or automation

• Custom installations in ovens, furnaces, HVAC systems and research equipment

Wire Quality and Performance Considerations
Measurement-grade thermocouple wire meets tight tolerance specifications, helping ensure consistency and accuracy when constructing or repairing thermocouples. Proper insulation and color coding make it easier to match wire to the correct thermocouple type and maintain signal integrity as temperature signals travel from the sensing junction back to your instrument.
