Compensation wires and compensation cables, to a certain temperature range (including room temperature) and the matching of the thermocouple thermoelectric emfs values the same pair with insulation layer or more wires or cables.Use them to connect the thermocouple and measuring devices, in order to compensate them with the error produced by the temperature change of the thermocouple junction.Compensation wires and compensation cables are divided into extension type and compensation type two kinds.
