Type J Thermocouple Probe (316 Stainless Steel Sheath, M20×1.5 Thread, IP65)
Product Overview
Type J thermocouple probe (as shown) from Huona New Material is a robust industrial temperature sensor featuring a Type J (Iron/Constantan) thermocouple junction, a 316 stainless steel protective sheath, and a brass connection head (IP65). Manufactured with precision welding and high-quality insulation, it delivers stable thermoelectric performance across -40℃ to 750℃ (continuous) / 800℃ (short-term). Ideal for petrochemical processing, industrial furnaces, and HVAC systems, it offers excellent oxidation resistance, reliable performance in harsh environments, and long-term durability.
Standard Designations & Core Material Foundation
- Thermocouple Type: Type J (Iron/Constantan; compliant with IEC 60584-2 Class 1)
- Key Specification:
- Sheath: 316 stainless steel; diameter: 8mm (customizable: 3–12mm); length: customizable (e.g., 300mm, 500mm, 1000mm)
- Connection head: Brass (IP65 protection, waterproof and dustproof)
- Mounting thread: M20×1.5 (standard industrial thread)
- Thermocouple wire: Iron (JP) / Constantan (JN), diameter: 0.5mm (customizable: 0.3–1.0mm)
- Sheath Material: 316 Stainless Steel (corrosion-resistant, high-temperature)
- Chemical Composition: Positive (JP): Pure Iron (Fe ≥99.5%); Negative (JN): Constantan (Cu 55% / Ni 45%)
- Compliant Standards: IEC 60584-2, ASTM E230, GB/T 4989, RoHS 2.0
- Manufacturer: Huona New Material, certified to ISO 9001 and IATF 16949
Key Core Advantages (Centered on Type J Stability & Brass Connection Head)
1. Reliable Performance in Reducing Atmospheres
- Superior Oxidation Resistance: Type J thermocouple exhibits excellent stability in reducing atmospheres and vacuum environments, making it ideal for applications where Type K is prone to degradation.
- Wide Temperature Range: Continuous operation from -40℃ to 750℃, suitable for a broad range of industrial temperature monitoring applications.
2. High Precision & Accuracy
- Class 1 Accuracy: Thermoelectric potential error ≤±1.1℃ (0–200℃) / ±0.4% t (200–750℃), meeting the precision requirements for industrial process control.
- Fast Thermal Response: Compact sheath design provides a thermal response time (τ₅₀) ≤2s in air at 500℃, ideal for dynamic temperature monitoring.
3. Rugged Construction & Environmental Resistance
- 316 Stainless Steel Sheath: Resists corrosion, abrasion, and mechanical impact, extending service life in harsh industrial environments (e.g., petrochemical, marine).
- IP65 Brass Connection Head: Brass head with IP65 protection, preventing ingress of dust and water, suitable for outdoor and wet industrial settings.
4. Secure Mounting & Easy Installation
- Standard M20×1.5 Thread: Enables secure, stable installation in process pipelines, equipment casings, and furnace walls, with adjustable insertion depth.
- Universal Compatibility: Compatible with most industrial temperature controllers, data loggers, and PLC systems.
5. Versatile Processability
- Flexible Termination: Connection head accommodates standard terminal blocks for easy wiring and maintenance.
- Customizable Options: Supports various sheath lengths, diameters, and mounting configurations to meet specific application needs.
