室内用双支铂热电阻WRN2-740 供应
产品概述
室内用双支铂热电阻WRN2-740是一款专为工业温度测量设计的精密传感器，采用优质铂丝作为感温元件，通过双支独立绕组结构实现两组同步温度信号输出。该产品适用于需要多点监测或冗余备份的室内环境，如实验室恒温系统、暖通空调设备、制药车间等场景，能够稳定测量-200℃至500℃范围内的介质温度，确保数据可靠性与系统安全性。815
核心技术特点
WRN2-740采用全密封不锈钢保护管设计（材质1Cr18Ni9Ti），具备优异的防潮、防腐蚀性能，特别适合长期在潮湿或含轻微腐蚀性气体的室内环境中使用。双支独立Pt100元件通过先进绕制工艺实现±0.3℃的高精度，热响应时间≤3秒，能快速捕捉温度变化。独特的抗电磁干扰屏蔽层设计，有效避免信号传输过程中的噪声干扰，配合三线制接线方式可消除导线电阻误差。产品机械强度达10MPa耐压，使用寿命超过常规单支热电阻30%以上。5610
应用场景与优势
在发电机组轴承监测、食品加工生产线、精密仪器温控系统等领域，WRN2-740可同时连接两套显示或控制仪表，实现温度数据的交叉验证与系统冗余。其紧凑型结构（总长可按需定制5000mm/7000mm）配合φ5.4mm柔性引线，便于在狭窄空间安装布线。与同类产品相比，该型号采用进口微型铂丝元件和聚四氟乙烯护套电缆，在30-50℃油浸或高湿环境下仍能保持稳定性能，解决传统热电阻引线易老化开裂的问题。91417

Product Overview
The WRN2-740 indoor dual-element platinum RTD is a precision temperature sensor designed for industrial applications. Featuring high-purity platinum wire sensing elements in dual independent windings, it provides two synchronous temperature outputs for redundant monitoring. Ideal for laboratories, HVAC systems, and pharmaceutical facilities, this device delivers stable measurements from -200℃ to 500℃ with enhanced data reliability. 815
Technical Highlights
Constructed with hermetic 1Cr18Ni9Ti stainless steel sheath, the WRN2-740 exhibits exceptional moisture and corrosion resistance for indoor harsh environments. Its dual Pt100 elements achieve ±0.3℃ accuracy via advanced winding technology, with ≤3s thermal response time. The anti-interference shielding layer and 3-wire configuration eliminate signal noise and lead resistance errors. With 10MPa pressure tolerance and 30% longer lifespan than single-element models, it ensures durable performance. 5610
Applications & Benefits
In power plant bearing monitoring, food processing lines, and precision instrument temperature control, the WRN2-740 enables cross-validation by connecting to dual displays/controllers simultaneously. The compact design (customizable 5000mm/7000mm length) with flexible φ5.4mm cables facilitates installation in confined spaces. Compared to conventional RTDs, its imported micro platinum elements and PTFE-jacketed cables maintain stability in 30-50℃ oil-immersion or high-humidity conditions, preventing cable degradation. 91417
Customization Options
Customers can select probe lengths (35mm standard), junction box protection ratings (waterproof/splash-proof), and cable lengths. Each unit undergoes 72-hour aging tests and -50℃~300℃ thermal cycling for performance consistency. We provide technical consultation and installation guidance to optimize temperature measurement layouts. 11120
