English Product Introduction
The WZPK-405S flameproof thermal resistor is specifically engineered for chemical processing environments with combustible media. Its integrated explosion-proof structure features precision-machined housing components and isolated internal chambers, effectively preventing contact between electrical sparks and hazardous substances, ensuring reliable temperature monitoring for chemical installations.
Constructed with austenitic stainless steel that undergoes multiple surface treatment processes, the device demonstrates enhanced corrosion resistance for prolonged exposure to acidic/alkaline media and organic solvents. The sensing element utilizes specially alloyed wires wound with high-purity magnesium oxide insulation, achieving optimal thermal conductivity while maintaining electrical isolation. The detachable terminal box cover facilitates efficient field wiring and maintenance operations.
This model operates effectively within standard chemical reaction temperature ranges, maintaining linear output characteristics even under significant thermal fluctuations. The dual-element design provides redundant temperature signals for critical equipment, compatible with DCS/PLC systems. Multiple process connection options including flanged and threaded types adapt to diverse installation requirements on pipelines, reactors, storage tanks, etc.
Ideal for petroleum refining, synthetic fiber production, and agrochemical synthesis processes, the product ensures intrinsic safety while improving control system accuracy through optimized thermal response time. The modular architecture allows maintenance personnel to replace components without interrupting production, significantly reducing operational costs.
