【English Part】
The armored platinum resistance thermometer WZPK-476U is a precision temperature sensing device engineered for industrial applications. Featuring a platinum thin-film sensing element and multi-layer protective structure, it delivers reliable long-term monitoring in challenging operating conditions. The product is widely adopted in petrochemical, power generation, and pharmaceutical industries due to its robust construction and measurement consistency.
Key Features:
-
Enhanced Durability
316L stainless steel armor with magnesium oxide insulation provides exceptional resistance to high temperature (up to 650℃), pressure fluctuations, and corrosive media. IP68-rated sealing ensures reliable operation in humid or dusty environments.
-
Rapid Thermal Response
Miniaturized sensing tip combined with compact encapsulation technology achieves fast heat transfer, delivering a typical thermal response time (T0.5) below 0.8 seconds for dynamic temperature monitoring scenarios.
-
Measurement Consistency
Multi-stage annealing process minimizes internal stress in platinum elements, maintaining accuracy within ±0.15%FS across the full range (-200℃~650℃). Long-term drift is controlled below 0.02% annually, reducing calibration requirements.
-
Configuration Flexibility
Customizable cable lengths (100mm-2000mm) and threaded connections (M12×1.5/M16×1.5) support diverse installation methods including flange, threaded, and compression fittings, compatible with DN15-DN250 pipelines.
-
System Integration
IEC 60751-compliant output supports Pt100/Pt1000 dual modes for seamless integration with PLCs and temperature transmitters. Built-in EMI shielding maintains signal integrity in electrically noisy environments.
The modular design simplifies maintenance procedures, allowing quick sensor replacement. Regular inspection of armor integrity is recommended to prevent media ingress. Proper selection of temperature range and installation orientation can extend service life beyond 8 years under typical operating conditions.
