Key Features of Fe-CuNi (Type J) Thermocouple:

1. Composition:

Positive Leg (Fe): Made of pure iron, which is cost-effective but prone to oxidation at higher temperatures.
Negative Leg (CuNi): Made of Constantan (copper-nickel alloy), which offers excellent stability and resistance to environmental effects.

2. Temperature Range:

Operational range: -40°C to 750°C (approximately -40°F to 1382°F).
Best suited for low to mid-range temperatures. Beyond 750°C, iron oxidizes quickly, limiting its effectiveness and lifespan.

3. Sensitivity (Seebeck Coefficient):

Voltage output: ~55 µV/°C (microvolts per degree Celsius).
This level of sensitivity allows for precise temperature measurement across its operational range.

4. Accuracy:

Accuracy is typically ±2.2°C or ±0.75% of the measured temperature, making it suitable for many industrial and laboratory applications.

5. Stability:

Offers good long-term stability in non-corrosive environments.
Iron's susceptibility to oxidation limits its use in environments with high oxygen or moisture levels at elevated temperatures.

6. Durability:

The Constantan leg is corrosion-resistant, while the iron leg requires protective sheaths or coatings to enhance durability in harsh conditions.
Type J is durable in moderate-temperature environments but less so in high-temperature or highly corrosive atmospheres.

7. Voltage Output:

Provides a higher output compared to Type K at similar temperatures, improving resolution and accuracy in low-temperature applications.
