【English Product Introduction】

The Armored Platinum Thin-Film RTD WZP-421D is a high-performance temperature sensor designed for industrial measurement applications, integrating advanced encapsulation technology with platinum thin-film processing to deliver reliable monitoring in challenging environments. Featuring a core sensing element made of high-purity platinum material enclosed in a precision-engineered stainless steel armored sheath, this product combines measurement sensitivity with long-term stability across wide temperature ranges.

Constructed with a seamless 316L stainless steel outer sheath and magnesium oxide insulation layer, the robust housing demonstrates exceptional corrosion resistance and mechanical durability, capable of withstanding high pressure, vibration, and particulate impact. The internal platinum sensing element is deposited on a ceramic substrate using thin-film technology, enhancing response speed while minimizing signal drift risk. Its compact design supports multiple installation configurations including threaded fixation, flange mounting, or direct immersion, adaptable to diverse industrial scenarios such as pipeline, tank, and reactor monitoring.

Operating within a -200°C to 600°C range, the WZP-421D exhibits linear output characteristics with optimized thermal conductivity pathways to reduce thermal equilibrium time, making it particularly suitable for dynamic temperature tracking. The built-in electromagnetic shielding layer effectively suppresses signal interference, while the fully welded hermetic sealing achieves IP68 protection level, ensuring reliable performance in humid, dusty, or mildly corrosive media environments.

This model finds extensive applications in temperature control systems across energy generation, petrochemical processing, pharmaceutical manufacturing, and food production sectors. It demonstrates strong environmental adaptability in steam pipeline monitoring, industrial kiln temperature regulation, and fluid medium detection scenarios. Multiple cable length and connector configuration options are available for field customization, supported by dedicated technical service teams to ensure efficient system integration and maintenance coordination.
