Type J Thermocouple Bare Wire Iron Constantan Alloy for Metal Smelting -40°C to 750°C Temperature Range
J-type thermocouple bare wire is a reliable temperature measurement solution specifically designed for metal smelting applications. Composed of iron-copper alloy (positive leg) and copper-nickel alloy (negative leg), this thermocouple utilizes the thermoelectric effect to provide accurate temperature monitoring in demanding industrial environments.
- Temperature Range: -40°C to 750°C (-40°F to 1382°F)
- Thermoemf Output: Microvolt (μV) level based on temperature changes
- Linear Characteristics: Excellent linear response across operating range
- Wire Composition: Iron (JP) positive leg, Cu-Ni (JN) negative leg
- Long-term Working Temperature: Up to 600°C (depending on wire diameter)
- Real-time melting process monitoring in smelting furnaces
- Precise temperature control and regulation systems
- Alloy composition control and quality assurance
- High-temperature environment temperature measurement
- Excellent oxidation resistance in high-temperature environments
- High measurement accuracy and stability
- Fast response time for real-time process control
- Reliable operation in metal smelting conditions
