補(bǔ)償導(dǎo)線與補(bǔ)償電纜是在一定溫度范圍內(nèi)（包括常溫）具有與所匹配的熱電偶的熱電動勢值相同的一對或多對帶有絕緣層的導(dǎo)線或電纜，用它們連接熱電偶與測量裝置，以補(bǔ)償它們與熱電偶連接處的溫度變化所產(chǎn)生的誤差，補(bǔ)償導(dǎo)線與補(bǔ)償電纜分為延長型和補(bǔ)償型兩種。
Compensational wire & cable are cables & wires with one pair or multi-pair and insulated layer with the same Pyro-EMF value of matched thermocouple within certain temperature. They are used to connect thermocouple and measuring devices to compensate the error resulting from temperature change on connection part. They are divided into two type including extension type and compensational type.
