The kx compensation wire is a pair of insulated wires that have the same nominal value of the thermoelectromotive force of the matched thermocouple within a certain temperature range (including normal temperature), and use them to connect the thermocouple and the measuring device to compensate them The error caused by the temperature change at the junction with the thermocouple. There are two types: extended type and compensated type.

kx compensation wire type, name and matching thermocouple:

Model Name Equipped with thermocouple Thermocouple indexing number Product model meaning

SC or RC copper-copper-nickel 0.6 compensation wire platinum rhodium 10-platinum thermocouple

Platinum rhodium 13- platinum thermocouple S or R S- indicates that the tolerance of thermoelectric characteristics is a precision compensation wire; P- indicates a shielded compensation wire; G- indicates a general compensation wire; V- polyvinyl chloride material (PVC) ; H- means heat-resistant compensation wire; F- PTFE material; R- means multi-strand compensation wire; B- alkali-free glass wire material
