Type T Thermocouple Extension Wire Essential For Temperature Control In Laboratories And Industrial Processes

Cu-CuNi, Type T thermocouple extension wire, is recognized for its accuracy and stability in temperature measurement, particularly in low to moderate temperature ranges. Composed of a copper (Cu) positive leg and a copper-nickel (CuNi) negative leg, Type T thermocouples are designed for temperatures between -200°C and 350°C. They offer high sensitivity, approximately 43 µV/°C, and are known for their repeatability and resistance to oxidation in moist conditions. Type T thermocouples are widely used in cryogenic applications, laboratory settings, food processing for temperature control during cooking or freezing, and various industrial processes where precise temperature monitoring is essential. Their versatility and compatibility with standard measurement equipment make them a popular choice for applications requiring reliable temperature data in moderate temperature environments.

Some Key Features Cu-CuNi (Type T) Constantan Thermocouple Wire include:

• Composition: Type T thermocouples consist of a positive leg made of pure copper (Cu) and a negative leg made of Constantan (CuNi), which is an alloy of approximately 55% copper and 45% nickel .
• Temperature Range: The operational temperature range for Type T thermocouples is from -200°C to +350°C . They are best suited for low to moderate temperature environments and are not advisable for use beyond this range due to the oxidation susceptibility of copper .
• Accuracy: Type T thermocouples have a high level of accuracy, with a sensitivity of about 43 µV/°C. They offer excellent repeatability between –200°C to 200°C .
• Advantages: Type T thermocouples are known for their high accuracy, stability, robustness, and resistance to oxidation. They perform well in the presence of moisture without oxidizing and are well-suited to oxidizing atmospheres .
• Insulation Material: MgO insulation is commonly used in Type T thermocouples due to its desirable characteristics such as fast response, compact size, broad temperature range, formability, weldability, durability, accuracy, and resistance to thermal shock and vibration .

In summary, Cu-CuNi (Type T) thermocouple extension wire is a reliable choice for temperature measurement in a variety of applications where low to moderate temperatures are involved.

Applications:

• Cryogenics: Type T thermocouples are reliable for ultra-low temperature measurements, making them ideal for cryogenic applications.
• Laboratory Environments: They are commonly found in laboratory settings for controlled experimental setups requiring precise temperature readings.
• Food Processing: Type T thermocouples are used for accurate temperature control during cooking or freezing processes in the food industry.
• Industrial and Commercial Temperature Sensing: These thermocouples play a pivotal role in industries such as power generation, oil/gas, pharmaceutical, biotech, cement, paper & pulp, and more, where precise temperature measurement is crucial.
• Domestic Appliances: Type T thermocouples are also used in everyday appliances like stoves, furnaces, and toasters for temperature sensing.
• Moist Environments: They perform well in the presence of moisture without oxidizing, making them suitable for use in moist environments.
• Oxidizing Atmospheres: Type T is well suited to oxidizing atmospheres, which adds to its versatility in industrial applications.

The Type T thermocouple extension wire's versatility, combined with its high accuracy and stability, makes it a popular choice for a range of temperature measurement applications.
