Product Overview
The WZP2-330B thermal resistor for power plant temperature measurement is specifically engineered for monitoring critical equipment such as boilers and steam turbines. Featuring dual Pt100 sensing elements housed in stainless steel protective tubes, it delivers reliable temperature data within -200°C to 420°C range. The waterproof junction box and flange mounting design ensure stable operation in high-humidity environments, making it suitable for 300MW-600MW generating units. Its dual-channel configuration allows simultaneous connection to multiple control systems. 1126
Technical Features
Manufactured with deep-blind-hole technology, the integrated protection tube exhibits exceptional pressure resistance (1.5x nominal pressure) and impact tolerance. The thermal response time is optimized to 90 seconds (16mm diameter) or 45 seconds (12mm version). Precision-wound sensing elements achieve B-grade accuracy of ±(0.30+0.005|t|)°C. Superior insulation maintains ≥100MΩ resistance between electrodes and sheath under 10-100VDC test voltage, ensuring performance in harsh plant conditions. 613
Structural Advantages
The removable flange design facilitates easy installation on steam pipelines, while the splash-proof junction box protects internal components. Available in 1Cr18Ni9Ti or 0Cr18Ni12Mo2Ti stainless steel, the protection tube resists various corrosive media. The separable sensing assembly enables quick maintenance without system shutdown, significantly reducing operational downtime. Customizable insertion depths (standard lengths 300-1150mm) accommodate diverse installation requirements. 521
Applications
This thermal resistor is widely implemented in coal-fired plants for boiler wall temperature monitoring, turbine bearing protection, and steam header measurement. Its vibration-resistant construction and high-pressure endurance make it ideal for petrochemical reactors, metallurgical furnaces, and other demanding industrial processes where reliable temperature data is crucial for operational safety and efficiency. 214
