Product Description
Type K Industrial Thermocouple Probe
Stainless Steel Sheath, M20*1.5 Thread, IP65 Protection
Product Overview
The Huona Type K industrial thermocouple probe is a rugged, general-purpose temperature sensor featuring a Type K (Chromel/Alumel) thermocouple junction, 304 stainless steel protective sheath, and blue cast aluminum connection head with IP65 rating. Manufactured with precision welding and high-quality insulation, it delivers stable thermoelectric performance across -40℃ to 1100℃ (continuous) / 1200℃ (short-term). Ideal for industrial furnaces, HVAC systems, petrochemical processing, and power generation applications.
Standard Designations & Core Materials
- Thermocouple Type: Type K (Chromel/Alumel) compliant with IEC 60584-2 Class 1
- Sheath Material: 304 stainless steel, corrosion-resistant for high-temperature applications
- Connection Head: Blue cast aluminum with IP65 protection (waterproof and dustproof)
- Mounting Thread: M20*1.5 standard industrial thread
- Compliant Standards: IEC 60584-2, ASTM E230, GB/T 4989, RoHS 2.0
- Manufacturer Certification: ISO 9001 and IATF 16949 certified
Key Advantages
Wide Temperature Range & Stability
Continuous operation up to 1100℃ with short-term capability to 1200℃. Stable EMF output with minimal drift ensures reliable measurement data for industrial temperature monitoring.
High Precision & Accuracy
Class 1 accuracy with thermoelectric potential error ≤±1.5℃ (0-400℃) / ±0.4% t (400-1100℃). Fast thermal response time (τ₅₀) ≤2s in air at 800℃ for dynamic monitoring.
Rugged Construction & Environmental Resistance
304 stainless steel sheath resists corrosion, abrasion, and mechanical impact. IP65-rated connection head prevents dust and water ingress for outdoor and wet industrial environments.
Secure Mounting & Easy Installation
Standard M20*1.5 thread enables secure installation in process pipelines and equipment. Universal compatibility with industrial temperature controllers, data loggers, and PLC systems.
