Introduction
The WRE-621A explosion-proof thermal resistor is specifically engineered for chemical industries, providing safe and accurate temperature measurement in hazardous environments with flammable gases, liquids, or vapors. Its robust construction ensures reliable performance in pipelines, reactors, and other critical equipment, supporting real-time temperature monitoring and control. Designed for compatibility with display instruments, it is widely used in fertilizer plants, petroleum refineries, and pharmaceutical processes.110
Key Features
Featuring a high-strength aluminum alloy housing and optimized internal spacing, the WRE-621A effectively isolates potential sparks from external explosive atmospheres. The downward-facing cable port prevents contamination, while its vibration-resistant design maintains accuracy under dynamic conditions. Suitable for Zone 1/2 hazardous areas with Group IIB and T4 classification, it eliminates the need for additional compensation cables, simplifying installation and reducing costs.1223
Specifications
With a temperature range of -200°C to 600°C and optional Pt100 sensing elements, the WRE-621A offers rapid response (τ0.5 ≤ 0.2–120S) and IP54-rated protection. Installation options include fixed flanges or threaded connections, with protective tubes available in carbon steel or stainless steel for corrosive media. Proper grounding and avoidance of high-temperature sources are recommended during deployment.717
Applications
Ideal for fertilizer pipeline monitoring, petrochemical reactor tracking, and pharmaceutical batch processing, this product excels in acidic/alkaline environments. Multi-point variants (e.g., WRE-240D) facilitate simultaneous measurements in distillation columns. Compliance with safety protocols during installation is essential to preserve its explosion-proof integrity.2526
