英文产品描述
The WSS-512 Bimetal Thermometer is a field-mounted instrument designed for medium-low temperature measurement in industrial applications. Featuring radial-type construction with parallel alignment between dial and protective tube, it provides clear visibility in confined spaces. The measuring range spans from -80℃ to +500℃, suitable for monitoring liquids, steam, and gases in petrochemical, power generation, and metallurgical processes. Environmentally friendly design eliminates mercury usage while maintaining measurement reliability. 2715
Constructed with spiral-wound bimetallic strip sensing element, the thermometer converts thermal expansion differential into precise pointer movement. The 1Cr18Ni9Ti stainless steel sheath offers corrosion resistance and 6.4MPa pressure tolerance. IP55-rated enclosure ensures operation in humid/dusty conditions. Modular core assembly allows in-service maintenance without process interruption. Multiple mounting options (NPT threads, flanges) adapt to diverse piping configurations. 3821
Key specifications include 100/150mm dial diameters, 1.5% accuracy, and ≤40s response time. Customizable immersion lengths (100-2000mm) and standard threads (M16×1.5, M27×2) enhance installation flexibility. Dual-layer rubber sealing prevents leakage, with operational ambient temperature from -40℃ to +85℃. Vibration-resistant design maintains stability in high-motion environments like textile machinery and marine propulsion systems. 111417
This instrument serves critical temperature monitoring in food processing (ovens, sterilizers), plastic injection molding, and pharmaceutical reactors. Energy sector applications include power plant auxiliary systems and pipeline heating networks. The adjustable-angle variant (WSS-481/581) accommodates challenging mounting positions, while contact version (WSSX-512) adds alarm functionality for threshold exceedance. Compact and maintenance-friendly, it effectively replaces traditional glass thermometers. 232515

工作原理
双金属温度计的工作原理是利用二种不同温度膨胀系数的金属,为提高测温灵敏度,通常将金属片制成螺旋卷形状,当多层金属片的温度改变时,各层金属膨胀或收缩量不等,使得螺旋卷卷起或松开。
由于螺旋卷的一端固定而另一端和一可以自由转动的指针相连,因此,当双金属片感受到温度变化时,指针即可在一圆形分度标尺上指示出温度来。这种仪表的测温范围是200~650℃,允许误差均为标尺两程的1%左右。
概述
双金属温度计的英文名称是bimetal thermometer;bimetallic thermometer,是一种适合测量中低温的现场检测仪表,可直接测量各种生产过程中的液体、蒸汽和气体介质温度。
双金属温度计主要的元件是一个用两种或多种金属片叠压在一起组成的多层金属片,利用两种不同金属在温度改变时膨胀程度不同的原理工作的。是基于绕制成环性弯曲状的双金属片组成。一端受热膨胀时,带动指针旋转,工作仪表便显示出热电势所应的温度值。
