WSSX-411型电接点双金属温度计产品介绍
WSSX-411型电接点双金属温度计是一款基于双金属传感原理设计的工业级温度监测与控制装置。该产品通过机械结构实现温度测量与接点信号输出的双重功能，适用于需要对温度变化进行实时监控并触发控制动作的工业场景。其表壳采用全不锈钢材质，防护等级达到IP65，可适应潮湿、粉尘等复杂工况环境。
该温度计的核心测温元件由两种不同膨胀系数的金属片复合而成，随着温度变化产生形变位移，带动表盘指针精准指示当前温度值。内置可调节式电接点装置，用户可通过旋转表盘外置旋钮独立设定上下限报警位置，当被测介质温度超过预设范围时，接点机构自动接通或断开控制电路，实现设备保护、流程联锁或声光报警功能。接点容量设计满足常规控制回路需求，接触电阻小且稳定性优异。
产品采用轴向或径向型表头结构，测温杆长度支持100mm至500mm定制，适用管道、罐体等不同安装需求。表盘直径标准化设计，黑色刻度线与白色表盘形成鲜明对比，在5米距离内可清晰辨读。工作温度覆盖-40℃至+500℃范围，基本误差控制在±1.5%量程以内，在持续震动小于25Hz的环境中仍能保持可靠工作。
WSSX-411型温度计已广泛应用于石油化工设备、工业锅炉系统、食品加工机械、中央空调机组等场景，其机械式结构无需外部供电即可长期稳定运行。产品制造过程严格执行质量管理要求，出厂前经过72小时连续工况模拟测试，确保每支温度计具备稳定的计量性能和防护能力。
WSSX-411 Bimetallic Thermometer with Electrical Contact Product Introduction
The WSSX-411 bimetallic thermometer with electrical contact is an industrial-grade temperature monitoring and control device based on bimetal sensing technology. This product integrates temperature measurement and electrical signal output through mechanical structure design, suitable for industrial applications requiring real-time temperature monitoring and control activation. Featuring an all-stainless-steel enclosure with IP65 protection rating, it demonstrates reliable performance in humid or dusty environments.
The core sensing element consists of two bonded metal strips with different thermal expansion coefficients. Temperature variations induce mechanical deformation, driving the dial pointer to accurately indicate current temperature values. The built-in adjustable electrical contact mechanism allows independent setting of upper/lower alarm thresholds via an external dial knob. When measured temperature exceeds preset limits, the contact system automatically opens or closes control circuits to activate equipment protection, process interlocking or alarm functions. The contact capacity meets standard control circuit requirements with low and stable contact resistance.
Available in axial or radial configurations, the thermometer supports probe lengths from 100mm to 500mm for pipeline or vessel installations. The standardized dial diameter features high-contrast black graduations on white background, ensuring legibility within 5 meters. Covering -40℃ to +500℃ measurement range, its fundamental error remains within ±1.5% of span while maintaining reliable operation under vibration below 25Hz.
This thermometer has been widely implemented in petrochemical equipment, industrial boiler systems, food processing machinery, and HVAC units. Its purely mechanical design ensures long-term stable operation without external power supply. Manufacturing processes adhere to strict quality protocols, with each unit undergoing 72-hour simulated operation tests before delivery to verify measurement consistency and environmental durability.
