All NANMAC thermocouple wire meets ANSI standards for the grade of wire specified; i.e. Extension, Standard or Special Limits of Error. A Certificate of Conformance is available with all wire at no charge upon request. A Certificate of Lot Wire Calibration, stating the actual deviation for a particular spool of wire is also available upon request, a charge may apply. NANMAC can also perform Certified Traceable Calibrations on a specific spool of wire or temperature sensor. This type of calibration is done based on your specified temperature points, contact the factory with your unique requirement for more information.

Selection and Use of Thermocouple and Thermocouple Extension Wire

Thermocouple wire can be fabricated into accurate and dependable thermocouples by joining the thermo- elements together at the sensing end. Thermocouple wire must be used to extend the Thermocouple to instruments where temperature limitations exceed that for use of TC extension wire. The conditions of measurement determine the type of Thermocouple wire and insulation to be used. Temperature range, environment, protection, insulation requirements, response and service life should be considered. The following parameters serve as a guide to the selection of wire.

Approximate Temperature Limits for Thermocouple Wire

Temperature limits for standard thermocouples that are protected with a closed end protecting tube are shown. These limits are suggested for continuous temperature sensing where insulation is not a factor. For unprotected thermocouples where fast response is required these operating limits should be reduced for equivalent service life.
