【English Product Introduction】
The WZPK-105U thin-film platinum RTD represents cutting-edge temperature sensing technology for industrial applications. Engineered with magnetron-sputtered platinum film on alumina substrates, this sensor delivers exceptional measurement consistency through precisely controlled laser trimming processes. Its compact design accommodates diverse installation requirements while maintaining outstanding performance across a broad operational range from -50℃ to 500℃, particularly excelling in environments with rapid thermal cycling.
Three key technological advancements distinguish this product: The vacuum-encapsulated platinum sensing element resists chemical corrosion and mechanical stress, achieving over 30,000 hours MTBF. Proprietary stress-relief layers minimize zero-point drift caused by thermal shock, maintaining long-term stability with annual drift below 0.03%FS. Modular terminal blocks support flexible 3-wire/4-wire configurations, adaptable to various industrial scenarios through customizable sheath solutions.
Technical specifications include dual Pt100/Pt1000 options with Class A accuracy (±0.15℃@0℃). The IP67-rated 316L stainless steel housing withstands pressures up to 6MPa, while optimized thermal response reaches τ0.5≤8s in liquid media. Advanced annealing techniques ensure linear output characteristics with less than 0.3% nonlinearity at 600℃. Standard process connections cover DIN/IEC-compliant G1/2 and NPT 1/4 thread types.
Customization services include probe lengths (50-2000mm), cable materials (PTFE/fiberglass/metal conduit), and connector configurations. Each unit undergoes rigorous 72-hour aging tests and multi-point calibration for batch consistency. Specialized variants are available for explosive atmospheres, sanitary processes, and high-vibration environments, supported by comprehensive technical consultation throughout project implementation cycles.
