Product Overview
The WZPK-233S armored platinum resistance thermometer utilizes imported platinum resistance elements as its core temperature-sensing component, delivering high-precision temperature measurement for industrial applications. With a compact diameter, excellent flexibility, and superior vibration resistance, this product is ideal for installations where conventional assembled platinum resistors cannot fit. Its stainless steel sheath, filled with high-density oxide insulation, ensures robust performance in harsh environments by combining contamination resistance with mechanical durability. The operating range spans from -200°C to 500°C, and it connects directly to secondary instruments via copper wires, providing reliable temperature signals for displays, recorders, and controllers.
Featuring a modular design, the product includes a sensing element, protective sheath, junction box, and multiple mounting options, with single or dual-element configurations (dual-element models output two synchronized signals). The junction box offers waterproof variants for diverse installation conditions, while fixation methods such as threaded or flanged mounts enable versatile deployment. The platinum element leverages the resistance-temperature characteristics of platinum wire for accurate measurements, supported by structural optimizations that enhance long-term stability and repeatability. 151724
技术优势
WZPK-233S在热响应时间、绝缘性能及兼容性方面表现突出。其热响应时间（t0.5）指温度阶跃变化时输出达到50%所需时间，优化设计显著提升了动态响应速度。常温绝缘电阻值不低于100MΩ（测试电压10～100VDC），保障了信号传输的稳定性。产品允许最大测量电流为5mA，避免过热影响精度。保护管材料采用1Cr18Ni9Ti不锈钢，兼顾耐腐蚀与承压需求，公称压力测试为1.5倍常规值，确保结构安全。
针对流动气体或液体测量场景，可选带固定螺栓接头的型号（如WZPK-233S），减少介质冲击影响。双支型号采用三线制引线，有效抵消导线电阻误差，适合高精度应用。用户可根据实际需求选择不同外径（如φ3mm～φ6mm）和插入深度，适配管道或设备空间限制。3712
Technical Advantages
The WZPK-233S excels in thermal response time, insulation performance, and compatibility. Its thermal response time (t0.5) — the duration required to reach 50% output after a temperature step change — is minimized through optimized design for rapid dynamic response. With a minimum insulation resistance of 100MΩ (tested at 10–100VDC), the product ensures stable signal transmission. The maximum measuring current is limited to 5mA to prevent accuracy degradation from self-heating. The 1Cr18Ni9Ti stainless steel sheath balances corrosion resistance and pressure tolerance, with a nominal pressure test of 1.5× rated value for structural integrity.
For measuring flowing gases or liquids, models with fixed bolt connections (e.g., WZPK-233S) mitigate medium impact. Dual-element versions employ a 3-wire lead configuration to cancel lead resistance errors, ideal for high-precision applications. Customizable outer diameters (e.g., φ3mm–φ6mm) and insertion depths accommodate spatial constraints in pipelines or equipment. 152428
