All THERMOCOUPLE WIRES, CABLES & EXTENSION WIRE | RTD CABLES & WIRES

Thermocouple grade wire is used in construction of a thermocouple temperature sensor. Thermocouple extension wire is used to carry the signal from the thermocouple sensor to the readout device while maintaining a high degree of accuracy. The extension wire material must match the material used in the positive and negative leg of the thermocouple type (e.g. type K) being used in the application. If a transmitter is installed within the thermocouple sensor assembly, copper wire is typically used in place of thermocouple extension wire to send the scalable (4 to 20) mA signal back to the process control equipment.

RTD sensors use ordinary copper instrumentation cable to send the resistance signal back to the recording, readout or control device. If a transmitter is installed within the RTD sensor assembly, copper wire is typically used to send the scalable (4 to 20) mA signal back to the process control equipment.

Pyromation stocks and sells a variety of sizes and gauges of thermocouple grade and extension wire, as well as wire insulators. We also offer special construction thermocouple wire and RTD cable, including multi-pair thermocouple extension wire.

Thermocouple and extension wires are generally ordered and specified by ASTM/ANSI designations for calibration.

Popular generic and trade name examples are:

Chromel®/Alumel® – ASTM/ANSI Type K
Iron/Constantan – ASTM/ANSI Type J
Copper/Constantan – ASTM/ANSI Type T
Chromel®/Constantan – ASTM/ANSI Type E
Nicrosil®/Nisil® – ASTM/ANSI Type N
Platinum/Platinum (10% Rhodium) – ASTM/ANSI Type S
Platinum/Platinum (13% Rhodium) – ASTM/ANSI Type R
Platinum (6% Rhodium)/Platinum (30% Rhodium) – ASTM/ANSI Type B
