【WZP2-330B Thermal Resistor Product Introduction (English Version)】
The WZP2-330B thermal resistor is an industrial-grade temperature sensor specifically engineered for power plant monitoring systems. With a measurable range spanning from -50℃ to +500℃, this device employs advanced platinum resistance technology to deliver precise temperature measurement. The robust 316L stainless steel sheath combined with high-density ceramic insulation ensures reliable performance under high-pressure and high-vibration operating conditions.
Featuring a platinum sensing element with linearity error within ±0.15% and annual drift below 0.05%, the sensor maintains measurement consistency over extended service periods. Its dual-sealed construction with vacuum-filled interstices achieves IP67 protection rating, effectively preventing moisture and particulate ingress. The compact probe design (6mm±0.2 diameter, customizable 150mm length) accommodates confined installation spaces, offering both axial and radial cable exit configurations for flexible integration with various power generation equipment.
Specialized manufacturing processes enhance environmental resistance: electrolytically polished sheath surfaces improve corrosion resistance against sulfur compounds, while 200℃-rated internal wiring prevents insulation degradation. Standard configuration includes 2-meter double-shielded armored cable with silver-plated copper conductors for stable signal transmission. Optional EMI filters are available for electromagnetic interference mitigation.
Customization services cover probe dimensions, cable lengths (extendable up to 50 meters), and connector types. Each unit undergoes rigorous 72-hour burn-in testing and thermal cycling validation before shipment. Comprehensive documentation including resistance-temperature reference tables and installation guidelines accompanies every product. For optimal performance, pairing with intelligent transmitters featuring cold junction compensation is recommended to ensure measurement accuracy in critical power generation applications.
