【Product Introduction in English】
The WZPK-165S explosion-proof platinum resistance thermometer is engineered for industrial process control applications in hazardous environments containing combustible gases or dust. Featuring a modular design with physical isolation and energy restriction mechanisms, this temperature sensing solution delivers reliable performance in potentially explosive atmospheres.
Constructed with high-purity platinum film elements using vacuum sintering technology, the device maintains precise conformity to international resistance-temperature characteristics across a broad measurement range from -200℃ to +500℃. Dual-layer 316L stainless steel armored sheathing with laser-welded seams provides complete hermetic sealing, achieving IP67 protection against corrosive media and mechanical stress. The explosion-proof terminal chamber incorporates multi-stage labyrinthine flamepath joints to safely contain electrical sparks and thermal energy.
Adaptable to diverse industrial scenarios including petroleum extraction, chemical processing, and material handling systems, the sensor supports flexible configuration of probe dimensions and standard mounting interfaces (flange, threaded, compression fittings). Integrated temperature compensation circuitry automatically adjusts for ambient variations, while electromagnetic shielding ensures stable signal transmission. Each unit undergoes 72-hour burn-in testing and multi-point calibration, demonstrating long-term stability with annual drift below 0.02% under typical operating conditions. This design emphasizes maintenance convenience with field-replaceable components and standardized connection protocols compatible with major control systems.
