【English Product Introduction】
The WZPK2306SA explosion-proof thermoresistor is specifically engineered for temperature measurement in hazardous chemical environments, delivering reliable performance in petrochemical plants, pharmaceutical facilities, and metallurgical applications. Its integrated explosion-proof architecture combines precision sensing technology with corrosion-resistant materials, providing enhanced safety and measurement consistency in flammable atmospheres.
Constructed with stainless steel housing and advanced ceramic insulation, the device achieves IP65 protection rating, effectively resisting dust ingress and high-pressure water exposure. The sensing unit employs multi-point welding technology and mineral oxide insulation layers, maintaining linear output characteristics across a broad temperature range from -200°C to +500°C, with annual temperature drift limited to 0.1%FS. The modular design facilitates swift maintenance, offering flexible installation through standardized M27×2 or G1/2 threaded connections.
Innovative multi-layer isolation technology integrates dual explosion-proof barriers between the sensing terminal and wiring chamber. Precision-engineered flameproof joints and gap control mechanisms effectively contain potential ignition sources. The corrosion-resistant alloy sheath and redundant sensing element design ensure long-term accuracy in sulfur-rich or acidic media. With response time under 5 seconds, the device captures real-time temperature fluctuations critical for process control.
This model excels in demanding applications including refinery reactors, polymerization towers, and solvent storage tanks. Its vibration-resistant structure withstands mechanical shocks within 15Hz-60Hz frequency range. The built-in self-diagnostic module continuously monitors sensor integrity, while standardized analog outputs enable seamless integration with DCS and PLC systems. Rigorous 72-hour burn-in testing and triple-stage thermal cycling validation guarantee operational stability under extreme conditions.
