Product Description


Explosion-Proof Type K Thermocouple (Stainless Steel Sheath, 16×300mm, 1000mm Probe Length)


Product Overview


Explosion-proof Type K thermocouple (as shown) from Huona New Material is a heavy-duty industrial temperature sensor designed for hazardous environments. It features a cast aluminum explosion-proof head, 304/316 stainless steel protective sheath, and Type K (Chromel/Alumel) thermocouple elements. Engineered to meet explosion-proof standards (Ex d IIB T6), it delivers stable measurement up to 1200℃ continuous / 1300℃ short-term, making it ideal for petrochemical, metallurgical, and power plant applications requiring safety and high-temperature reliability.

Standard Designations & Core Material Foundation


  • Thermocouple Type: Type K (Chromel/Alumel; IEC 60584-2 Class 1)
  • Explosion-Proof Grade: Ex d IIB T6 (suitable for Zone 1/2 hazardous areas)
  • Sheath Material: 304 Stainless Steel (optional 316/316L for corrosion resistance)
  • Sheath Specification: 16mm (diameter) × 300mm (insertion length); total probe length (head to tip) 1000mm
  • Conductor Specification: 2×1.0mm (MgO insulated, high-temperature)
  • Head Material: Cast aluminum (IP65/IP67 protection)
  • Process Connection: M20×1.5 or 1/2" NPT (threaded mounting)
  • Compliant Standards: IEC 60584-2, GB/T 4989-2013, ATEX, IECEx, RoHS 2.0
  • Manufacturer: Huona New Material, certified to ISO 9001 and IATF 16949

Key Core Advantages (Centered on Explosion-Proof & Heavy-Duty Design)


1. Explosion-Proof Safety & Reliability


  • Ex d IIB T6 Certification: Cast aluminum explosion-proof head prevents ignition of flammable gases/vapors, ensuring safe operation in oil refineries, chemical plants, and gas pipelines.
  • IP67 Protection: Sealed head and MgO insulation resist dust, water, and oil mist, suitable for outdoor and harsh industrial environments.

2. Ultra-High-Temperature Performance


  • 1200℃ Continuous Operation: MgO-insulated stainless steel sheath withstands extreme heat, with no insulation breakdown or element drift after 1000 hours at 1100℃—far exceeding standard thermocouple limits.
  • Fast Thermal Response: 16mm diameter sheath provides a thermal response time (τ₅₀) ≤3s in air at 1000℃, ideal for dynamic high-temperature monitoring.

3. Rugged Mechanical & Mounting Design


  • Heavy-Duty Sheath: 16mm diameter stainless steel sheath resists bending, vibration, and mechanical impact, suitable for high-flow pipelines and furnace applications.
  • Threaded Mounting: M20×1.5 or 1/2" NPT connection enables secure installation in pressure vessels and process pipelines, with adjustable insertion depth.
