WSSX414电接点双金属温度计是一种广泛应用于工业现场的温度测量与控制仪表。它能够直接测量生产过程中-80℃至+500℃范围内的液体、蒸汽和气体介质温度。该温度计采用双金属片作为感温元件，当温度变化时，双金属片会发生形变，从而带动指针转动，指示出温度的变化值。它还带有电接点装置，当温度达到预设的上下限值时，能够自动触发继电器动作，实现自动控制和报警功能。

这种温度计具有多种结构形式，能满足不同安装和使用要求。其表壳通常采用铝板拉伸成型，表面经过黑色电泳处理，具有良好的防水防腐性能。保护管等部件则多采用1Cr18Ni9Ti等不锈钢材料，坚固耐用。在正常工作大气条件下，温度计的性能稳定可靠。

The WSSX414 electric contact bimetallic thermometer is a widely used temperature measuring and control instrument in industrial fields. It can directly measure the temperature of liquid, steam, and gas media in the range of -80℃ to +500℃ during the production process. The thermometer uses bimetallic strips as temperature sensing elements. When the temperature changes, the bimetallic strips deform, causing the pointer to rotate and indicate the temperature change. It is also equipped with an electric contact device, which can automatically trigger the relay action when the temperature reaches the preset upper and lower limit values, achieving automatic control and alarm functions.

This thermometer is available in various structural forms to meet different installation and usage requirements. The housing is usually made of aluminum plate by drawing, with a surface treated by black electrophoretic coating, providing good waterproof and corrosion-resistant properties. The protective tube and other components are often made of stainless steel materials such as 1Cr18Ni9Ti, which are strong and durable. Under normal working atmospheric conditions, the performance of the thermometer is stable and reliable.
