High Accuracy Type T Thermocouple Wire Positive Leg Cu(TP) With Copper Positive Leg For Low-Temperature Measurements

High Accuracy Type T Thermocouple Wire Positive Leg Cu(TP) With Copper Positive Leg For Low-Temperature Measurements

The positive leg of Type T thermocouple wire, designated as Cu(TP), is composed of pure electrolytic copper (≥99.9% purity). This material offers a stable and predictable thermoelectric response when paired with the negative leg (constantan, a Cu-Ni alloy). Common applications include food processing, HVAC systems, refrigeration, and laboratory equipment. Cu(TP) ensures reliable performance in non-aggressive environments, balancing durability and cost efficiency.

Composition & Properties:

• Positive Leg (TP): Pure Copper (~99.9%)
• Temperature Range: -200°C to 350°C
• Accuracy: ±1.0°C or 0.75% (Standard), ±0.5°C or 0.4% (Special)
• Electrical Conductivity: High (similar to pure copper)
• Corrosion Resistance: Good in dry air but prone to oxidation in humid environments
• EMF Output: ~40.69 µV/°C at 0-100°

Thermocouple temperature range and tolerance

Key Features of Type T Positive Leg (Cu, TP):

• Temperature Range: Operates effectively from -200°C to +350°C (-328°F to +662°F), ideal for cryogenic and moderate-temperature applications.
• Precision: Provides high accuracy (±0.5°C typical) and linear output, making it suitable for calibration and control systems.
• Corrosion Resistance: Resists oxidation in dry environments but requires protection in humid or corrosive conditions.
• Cost-Effectiveness: More affordable than noble-metal thermocouples (e.g., Type S/R/B).
• Flexibility: Available in various gauges (e.g., 30AWG to 12AWG) for different installation needs.

Applications:

• Cryogenic Temperature Measurements:

Used in laboratories and industrial applications requiring precise low-temperature measurements (-200°C and below).

Common in liquid nitrogen and liquefied natural gas (LNG) monitoring.

• Food Processing & Storage:

Used in food safety monitoring, refrigeration units, and cold storage systems.

Helps ensure compliance with food industry standards (e.g., HACCP).

• Biomedical & Pharmaceutical Industry:

Monitoring temperatures in medical storage units for vaccines and pharmaceuticals.

Used in incubators and cryogenic freezers.

• Environmental Monitoring & Meteorology:

Used in weather stations, climate research, and environmental studies.

Ideal for measuring soil, water, and air temperatures.

• Industrial Applications:

Suitable for plastics molding, HVAC systems, and scientific equipment calibration.

Used in temperature-sensitive electrical components.

• Aerospace & Automotive Industry:

Helps in cold chamber testing of aircraft and automotive components.

Used in space research for measuring extreme temperature conditions.

Key Advantages:

• High Accuracy & Stability – Excellent for precision measurements in critical industries.
• Wide Temperature Range – Functions efficiently from cryogenic to moderate temperatures.
• Corrosion Resistance – Performs well in humid and wet environments.
• Non-Magnetic – Suitable for sensitive applications.

Limitations:

• Prone to Oxidation – Copper oxidizes at high temperatures, limiting its range.
• Soft Metal – Susceptible to mechanical damage and requires careful handling.

The Cu (TP) positive leg in Type T thermocouples is a reliable, high-accuracy option for low-to-moderate temperature applications. Its strong thermal conductivity, corrosion resistance, and non-magnetic properties make it ideal for food processing, medical storage, environmental monitoring, and cryogenic research.
