Type “K” thermocouple
6、conductors are typically used as extension leads for aerospace application. These wires are only to be used in a matched pair and procured under AS5419. Thermocouple extension wires are calibrated for use together in fabricating thermocouples. If each leg of the thermocouple extension wire is from a
7、 different lot, recalibration of the thermocouple pair will be required.FIGURE 1 - Wire, Thermocouple, PTFE - PolytetrafluoroethyleneComponent wire insulation system must conform to the similar wire type designatedin Table 1 of AS5419.
