【English Product Introduction】
The WZPK-335S explosion-proof platinum resistance thermometer is engineered for precise temperature measurement in demanding industrial environments. Featuring industrial-grade platinum sensing elements and multi-layer protective construction, this device delivers stable temperature monitoring and reliable signal transmission, specifically designed for applications in combustible gas or dust atmospheres. The housing, crafted from high-strength alloy with anti-corrosion surface treatment, demonstrates exceptional resistance to chemical erosion in prolonged service.
Incorporating modular design philosophy, the sensor head integrates an explosion-proof isolation chamber with specialized threaded connection mechanism, achieving effective energy containment between internal components and hazardous environments. The probe employs hermetic welding technology combined with dual-layer armored protective tubing, maintaining excellent thermal response while enhancing mechanical durability. The terminal compartment contains explosion-proof wiring terminals compatible with multiple cable connection configurations, facilitating field installation and maintenance optimization.
This temperature measurement instrument covers a standard operating range from -200℃ to +500℃, delivering measurement accuracy better than ±0.3℃ under normal working conditions. Its unique vibration-damping structure effectively mitigates measurement deviations caused by mechanical vibration, making it suitable for dynamic equipment such as pumps and compressors. The wetted parts can be customized with various materials including 316L stainless steel and Hastelloy alloys to accommodate diverse application requirements in petrochemical, natural gas processing, and industrial furnace systems. The optimized thermal dissipation design ensures consistent performance during continuous operation by minimizing measurement errors induced by temperature gradients.
