Thermocouple Wire

Thermocouple wire is a special insulated wire which is available in thermocouple grade or the extension grade. Read More

An extension grade wire is a preferred choice for connection of thermocouples and the control or sensing equipment. Thermocouple Wires are generally high temperature cables, which are designed with different insulations to fit in different environmental conditions and for this reason; you are required to go for the one that best suits your measurements.

Standards and Certifications

• Flame test 383
• ASTM B3 and B8
• UL Standard 13

• Conductor

Thermocouple Wires have different measurements in accordance to American Wire Gauge (AWG). However, they rarely exceed 10 feet long. They are made of copper conductors which are stranded or tinned for maximum performance.

• Insulation

They are insulated for chemical and mechanical protection by:

a) Polyvinyl Chloride (PVC)
b) Ethylene Propylene Rubber (EPR)
c) Ethylene Propylene Diene Monomer (EPDM)

• Shielding

Shielding prevents the conductors from overlapping, thus holding them in their position. This helps in maintaining the circular phase identification of thermocouple cables.

• Jacketing

Jacketing is what houses the cable. This layer offers an additional protection to the cable and the handler and keeps the cable structure together. Thermocouple Wires are jacketed by fiberglass braid to withstand high temperature conditions.


a) Motor engines
b) Food Processing
c) Petrochemical
d) Geothermal industries
