Products Description

The bare wire of T-type thermocouple is an important temperature sensor element, composed of two different materials of metal wires (usually copper/conventional copper nickel alloy). It uses the small voltage difference generated by these two metals at different temperatures to measure temperature changes. The bare wire of T-type thermocouple has high sensitivity and stability, and can work reliably in the range of -200 ° C to up to 400 ° C. Due to its excellent performance in low-temperature environments, T-type thermocouple bare wires are often used in low-temperature laboratories, refrigeration equipment, food processing, and the pharmaceutical industry. Its high sensitivity and reliability make T-type thermocouple bare wire highly favored in application scenarios that require accurate temperature measurement.

Parameter

Copper nickel thermocouple (T-type thermocouple), also known as copper constantan thermocouple, is the best inexpensive metal thermocouple for measuring low temperatures. Its positive electrode (TP) is pure copper, and its negative electrode (TN) is a copper nickel alloy, commonly known as constantan. It is compatible with the constantan EN of nickel chromium constantan, and cannot be compatible with the constantan JN of iron constantan, although they are both called constantan.

The measurement temperature range of copper nickel thermocouple is -200~350 ° C.

Notes:

T-type thermocouples are not suitable for high-temperature environments because their performance at high temperatures is not as good as other types of thermocouples.

In oxidizing atmospheres, the performance of T-type thermocouples may be affected, especially when copper electrodes are prone to oxidation.

Due to the relatively low thermoelectric potential of T-type thermocouples, they are not suitable for applications that require high sensitivity measurements.
