【产品中文介绍】
WSSX-480B隔爆双金属温度计是一款专为工业安全场景设计的温度测量仪表，适用于石油、化工、天然气等易燃易爆环境。该产品通过特殊结构设计实现隔爆保护功能，在确保测量精度的同时有效保障设备与人员安全。

核心特点：

1. 安全稳定结构
   采用全密封壳体与防爆接合面设计，内部元件与外部环境完全隔离。双层防护结构可承受高强度冲击，在复杂工况下仍能保持稳定运行。温度测量范围覆盖-40℃至+500℃，满足多数工业场景需求。

2. 耐用测量系统
   核心传感元件选用高品质双金属片，通过精密焊接工艺提升热响应速度。螺旋形弹性元件设计使指针回差小于全量程的1%，确保长期使用后仍保持±1.5%的示值精度。

3. 人性化设计
   表盘采用高对比度白色基底与黑色刻度组合，搭配夜光指针便于昏暗环境读数。支持轴向/径向/万向三种表头安装方向，配备M27×2标准螺纹接口，适配多数工业管道安装需求。

4. 环境适应性
   壳体表面经过多层防腐处理，可耐受PH3-H2S-CO2混合腐蚀性气体。防护等级达到IP65，在粉尘、油污或潮湿环境中均可正常工作，工作环境温度覆盖-20℃至+60℃。

应用领域：
广泛应用于油气储运、化工厂反应釜、冶金设备加热炉等场景的温度监控，特别适用于泵房、压缩机站等存在爆炸风险的特殊区域。可根据需求提供不锈钢304/316L壳体选配，支持表盘尺寸100mm/150mm定制。

服务支持：
提供专业技术咨询与选型指导，支持非标规格定制开发。产品出厂前经过72小时连续工况模拟测试，配备完善的售后服务体系。

【Product Description in English】
The WSSX-480B Explosion-proof Bimetallic Thermometer is engineered for industrial safety applications, specifically designed for hazardous environments including petroleum, chemical and natural gas facilities. Its explosion-proof construction ensures reliable temperature measurement while maintaining operational safety.

Key Features:

1. Robust Safety Design
   The fully sealed housing with reinforced joints provides complete isolation between internal components and external environment. Dual-layer protection structure withstands intense mechanical impact, maintaining stable performance within -40℃ to +500℃ measurement range.

2. Precision Sensing System
   High-grade bimetallic strip ensures measurement consistency through precision welding technology. Helical spring mechanism minimizes pointer hysteresis to less than 1% of full scale, guaranteeing ±1.5% accuracy throughout extended service life.

3. Ergonomic Configuration
   High-contrast white dial with black graduations and luminous pointer enables clear reading in low-light conditions. Offers axial/radial/universal mounting options with standard M27×2 threaded connection, compatible with most industrial piping systems.

4. Environmental Resistance
   Multi-layer anti-corrosion coating protects against PH3-H2S-CO2 mixed corrosive gases. IP65 protection rating ensures reliable operation in dusty, oily or humid environments, with ambient temperature tolerance from -20℃ to +60℃.

Application Scope:
Ideal for temperature monitoring in oil/gas storage tanks, chemical reactors, metallurgical heating furnaces, particularly suitable for pump houses and compressor stations with explosion risks. Optional 304/316L stainless steel housings available, customizable with 100mm/150mm dial sizes.

Service Commitment:
Professional technical consultation and model selection guidance provided. Customized solutions available for special requirements. All products undergo 72-hour continuous simulation testing before delivery, backed by comprehensive after-sales support system.
