6、EW POLICY. Type “K” thermocouple 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 ther
7、mocouple extension wire is from a different lot, recalibration of the thermocouple pair will be required.FIGURE 1 - Wire, Thermocouple, PTFE - PolytetrafluoroethyleneOuter surface must be smooth, homogeneous PTFE with no mineral filler exposed.Component wire insulation system must conform to the sim
