Within the normal temperature range below 100%C, extension wire has the same character as nominal value of thermal electromotive force of matched thermocouple. And it can extend the reference junction of thermocouple when connecting with thermocouple. Extension wire can be divided into extension type and compensation type. Its advantage is to improve flexibility of circuit and make wiring convenient. At the same time, it can adjust line resistance and prevent outside interference. What’s most important is that it can reduce cost of circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"IndustriElectric","offers":[{"title":"Default Title","offer_id":43588843176071,"sku":null,"price":98.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0640\/2818\/0615\/files\/Screenshot2025-12-10194129.png?v=1765417311","url":"https:\/\/industrielectric.com\/products\/thermocouple-t-type-sheath","provider":"IndustriElectric","version":"1.0","type":"link"}
