opis produktu
Huona J-Type Thermocouple Bare Wire SWG30/SWG25/SWG19 High Thermal Sensitivity
Product Overview
Type J thermocouple bare wire, a high-precision temperature-sensing element crafted by Huona New Material, consists of two dissimilar alloy conductors--iron (positive leg) and constantan (copper-nickel alloy, negative leg)--engineered for accurate temperature measurement in moderate-temperature environments. Available in three standard wire gauges: SWG30 (0.305mm), SWG25 (0.51mm), and SWG19 (1.02mm), this bare wire eliminates insulation interference, making it ideal for custom thermocouple assembly, high-temperature calibration, and applications requiring direct contact with measured media.
Standard Designations
- Thermocouple Type: J (Iron-Constantan)
- Wire Gauges: SWG30 (0.315mm), SWG25 (0.56mm), SWG19 (1.024mm)
- International Standards: Complies with IEC 60584-1, ASTM E230, and GB/T 4990
- Form: Bare wire (uninsulated, for custom insulation/protection)
- Manufacturer: Huona New Material, certified to ISO 9001 and calibrated to national temperature standards
Key Advantages
- Gauge-Tailored Performance: SWG30 (thin gauge) offers high flexibility for tight-space installations; SWG19 (thick gauge) provides enhanced mechanical strength for industrial environments; SWG25 balances flexibility and durability for general-purpose use.
- Superior Thermoelectric Accuracy: Generates a stable electromotive force (EMF) with a sensitivity of ~52 μV/°C (at 200°C), outperforming Type K in the 0-500°C range, with Class 1 accuracy.
- Bare Wire Versatility: No pre-applied insulation allows users to customize protection based on specific temperature/corrosion requirements.
- Cost-Effective: Iron-constantan alloy is more affordable than precious metal thermocouples while delivering higher sensitivity than Type K.
- Good Oxidation Resistance: Performs reliably in oxidizing environments up to 750°C.
