منتوج وصف
Product Overview
This economical Type J Iron-Constantan flat thermocouple strip is independently produced by Huona for medium and low-temperature industrial temperature measurement scenarios. It adopts strictly matched Iron positive conductor and Constantan negative conductor alloy pair, processed via medium-thickness precision rolling and soft stress-relief annealing craft. The flat strip features consistent dimensional tolerance, bright scratch-resistant metallic surface and stable thermoelectric output under 0~750°C working range. Delivered in multiple plastic spools fully wrapped with transparent protective film as shown in the picture, the packaging effectively isolates dust and oxidation during transit, perfectly suited for mass production of medium-temperature contact sensors, machinery surface temperature probes and cost-controlled thermal monitoring components for general manufacturing workshops.

Key Differentiating Advantages
1. Standard Iron-Constantan Alloy Matching for Medium-Low Temp Sensing
This flat thermocouple strip uses classic Type J Iron-Constantan alloy combination with rigorous raw material composition control. Each production batch undergoes dedicated thermoelectric calibration to deliver highly linear signal response within its designated temperature span, effectively reducing reading deviation for routine medium-temperature detection. The mature alloy formula maintains stable performance batch after batch to lower overall production cost for sensor manufacturers.
2. Excellent Stability in Medium-Low Dry Thermal Environments
The alloy pair exhibits reliable anti-oxidation capacity under temperatures below 750°C in dry air. It avoids rapid surface rust and oxide layer buildup during long-cycle medium-temperature heating, preventing gradual loss of sensing precision and extending the service life of general-purpose industrial thermocouple probes for ovens and forming equipment.
3. Optimized Soft Annealing Balances Bendability & Structural Stability
Stress-relief soft annealing eliminates internal rolling residual stress, granting the strip outstanding pliability for tight winding, stamping and surface laminating without cracking or permanent warping. The medium thickness flat profile creates sufficient contact area for accurate thermal signal capture, while remaining flexible enough for assembly in moderately confined installation spaces.
4. Multi-Spool Film Packaging Preserves Original Surface Quality
All spools are individually sealed with transparent protective film to shield the polished strip surface from scratches, dust and air oxidation during transportation and inventory storage. Precision closed-loop rolling and slitting technology ensures ultra-uniform thickness and width across the full reel length, with smooth deburred edges that will not damage insulation sleeves during sensor encapsulation procedures.
5. High Cost-Performance for Mass General Industrial Applications
Compared with high-temperature thermocouple alloy series, this Iron-Constantan flat tape delivers reliable temperature measurement performance at a more competitive material cost. It maintains consistent mechanical and thermoelectric properties through frequent medium-low temperature cycling, serving as an economical core material for daily factory thermal monitoring and routine equipment temperature tracking.
