产品名称：WSSX-484电接点双金属温度计 / WSSX-484 Bimetallic Thermometer with Electrical Contact
中文产品介绍：
WSSX-484电接点双金属温度计是一款专为工业温度测量与控制设计的机械式仪表。其核心部件采用双金属传感元件，通过金属片的热膨胀特性实现温度指示，同时配置可调节接点装置，可对温度进行定点控制或报警输出。产品适用于液体、气体及蒸汽介质的温度监控，具备直观显示与电气控制双重功能。
该温度计表壳采用不锈钢材质，表盘直径为100mm，支持轴向或径向安装方式。测量范围覆盖-80℃至+500℃，满足不同场景需求。表内接点装置采用磁助式结构，接触信号稳定，最大接点容量可达AC 220V/1A，可直接驱动小型继电器或报警装置。防护等级达到IP65，可适应潮湿、粉尘等复杂工况环境。
产品核心优势体现在三个方面：其一，机械结构设计简洁可靠，无需外部电源即可实现温度指示；其二，接点位置可通过表盘外置旋钮灵活调节，设定温度误差不超过量程的±1.5%；其三，表壳内部填充硅油阻尼液，有效减少指针震动，延长使用寿命。广泛应用于热力管道、机械设备、化工反应釜等场景的温度监控，特别适合需要就地显示与电气联动的控制系统。
使用建议：安装时需注意介质流向与感温管方向一致，定期校准指针零点。接点装置建议配合中间继电器使用，避免直接控制大功率负载。建议每12个月进行机械部件检查，清理接点表面氧化层。
英文产品介绍：
The WSSX-484 Bimetallic Thermometer with Electrical Contact is a mechanical instrument designed for industrial temperature measurement and control. Utilizing a bimetallic sensing element that operates on thermal expansion principles, this device provides clear temperature indication while integrating adjustable electrical contacts for preset control or alarm functions. Suitable for monitoring liquid, gas, and steam media, it combines visual readout with electrical control capabilities.
Constructed with stainless steel housing and available in 100mm dial size, the thermometer supports axial or radial mounting configurations. Its measurement range spans from -80℃ to +500℃, accommodating diverse application requirements. The magnetically assisted contact mechanism ensures stable signal transmission, supporting up to AC 220V/1A contact capacity for direct operation of relays or alarm systems. With IP65 protection rating, it reliably operates in humid or dusty environments.
Key advantages include: 1) Self-powered mechanical operation requiring no external energy source for temperature indication; 2) Externally adjustable set point dial with ±1.5% full-scale accuracy; 3) Silicon oil damping system minimizing pointer vibration and extending service life. Typical applications encompass thermal pipelines, mechanical equipment, chemical reactors, and other systems requiring local display with electrical interlocking.
Installation guidelines: Align the thermal probe with medium flow direction. The contact system should connect through intermediate relays when controlling high-power loads. Routine maintenance includes zero-point calibration and annual inspection of mechanical components, with periodic cleaning of contact surfaces recommended.
