The Material Code of SC Wires
The conductor of SC compensating wires is made of copper-nickel alloy (commonly known as constantan), and the outer insulation is mostly high-temperature resistant polyvinyl chloride or silicone rubber. This combination is like putting an "air-conditioned suit" on the wire: the copper-nickel alloy can automatically offset the resistance fluctuations caused by temperature changes, while the special insulation layer can remain stable in environments ranging from -60℃ to 260℃, making it particularly suitable for industrial scenarios with large temperature differences.
Why It Is Unaffected by Alternating Temperatures
Intelligent Compensation: The resistance temperature coefficient of the copper-nickel alloy perfectly matches that of the thermocouple, automatically correcting temperature measurement errors.
Double Protection: The insulation layer is both resistant to chemical corrosion and mechanical wear, like putting a bulletproof vest on the wire.
Flexible Adaptability: Different thicknesses and specifications can cope with strong electromagnetic interference or high bending frequency requirements.
Three Golden Rules for Purchasing
Check the Color Marking: The positive electrode has a red insulation layer, and the negative electrode is mostly blue or white.
Test Flexibility: High-quality SC wires can withstand more than 30 bends per minute.
Smell the Odor: Qualified products should have no pungent odor when heated to 200℃, proving the purity of the material.
