As a temperature sensor, thermocouple is usually used with display instruments, recording instruments and signal conditioners. Sheath thermocouple also can be used as a temperature sensing element for assembly thermocouple.Specification:1. S/E/K/J/T type thermocouple temperature range and accuracy chart

Thermocouple installation diagramTips: Extension wire of thermocoupleExtension wire of thermocouple is often constituted by alloy wire, insulating layer, protective jacket and shielding layer of extension wire. 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.How to select and connect extension wire? The same kind of extension wire is matched with the same kind of thermocouple. The negative and positive poles of extension wire should be correctly connected according to color. The length of extension wire should be no more than 15 meters to enhance anti-interference.
