Type T Thermocouple – Copper Constantan Temperature Sensor for Low-Temperature Precision Applications

Type T thermocouple is a high-accuracy temperature sensor designed for low-temperature and moisture-prone environments. Constructed from Copper–Constantan (Cu-CuNi) conductors and protected by a mineral-insulated sheath, it delivers excellent stability, repeatability, and long-term performance, especially in sub-zero and cryogenic applications.

Compliant with international standards such as IEC 60584 and ASTM E230, our type T thermocouples are widely used in food processing, pharmaceutical storage, environmental testing, laboratory equipment, and HVAC systems where precise low-temperature measurement is critical.

FAQ

1. What is a T-type thermocouple made of?

A T-type thermocouple is made of copper (positive leg) and constantan (negative leg, copper-nickel alloy).

This material combination offers excellent stability, good linearity, and reliable performance at low to moderate temperatures, making Type T especially suitable for laboratory, refrigeration, food processing, and cryogenic applications.

2. What is the temperature range of a T-type thermocouple?

The typical operating range of a T-type thermocouple is approximately –200°C to +350°C (–328°F to +662°F) for most industrial probes.

In some cases, thermocouple-grade wire may cover a broader range, but the actual usable temperature depends on factors such as:

  • sheath material
  • insulation type
  • probe construction
  • operating environment

For most practical industrial applications, –200°C to +350°C is the commonly recommended range.

3. What is the T-type thermocouple color code?

Under ANSI/ASTM color coding, a T-type thermocouple is commonly identified as:

  • Positive leg (Copper): Blue
  • Negative leg (Constantan): Red

However, color codes may vary by region or standard, especially between ANSI and IEC systems. To avoid wiring errors, always confirm the polarity and wire identification with the supplier’s datasheet before installation.

4. How accurate is a T-type thermocouple?

T-type thermocouples are known for good accuracy and excellent repeatability, especially at lower temperatures.

Typical accuracy depends on the wire grade and tolerance class:

  • Standard grade: typically around ±1.0°C
  • Special Limits of Error (SLE): typically around ±0.5°C

Actual performance may vary depending on:

  • sensor construction
  • wire quality
  • calibration condition
  • measuring instrument

For precision applications, calibrated or SLE Type T thermocouples are usually recommended.

5. What is the measurement uncertainty of a T-type thermocouple?

The measurement uncertainty of a T-type thermocouple depends not only on the sensor itself, but also on the complete measurement system.

Typical sources of uncertainty include:

  • thermocouple tolerance
  • cold junction compensation (CJC)
  • transmitter or instrument accuracy
  • calibration method
  • installation environment

In most applications, the sensor’s own tolerance is only one part of the total system uncertainty. For critical measurements, a full calibration and uncertainty evaluation is recommended.

6. How sensitive is a T-type thermocouple?

A T-type thermocouple has a sensitivity of approximately 43 µV/°C near common reference temperatures.

This relatively high output makes Type T a good choice for:

  • low-temperature measurement
  • high-resolution sensing
  • stable signal acquisition

Its sensitivity is one reason why Type T is widely used in scientific, medical, refrigeration, and food temperature monitoring applications.

7. What is the difference between Type K and Type T thermocouples?
