热电偶作为温度传感元件在数据收集、设备检测、工业制造方而获得了广泛应用。它的主要优点是,价格低廉、使用寿命长、测量温度可高达数千度。事实上,当温度达650℃时,热电偶与非接触式红外线高温仪是唯一有效的温度测量工具。所有这些特点使得热电偶在众多领域中有着广泛的应用。然而,要真正作到测温准确,必须遵循一些基本准则并对其基本构造有一定了解。当把两种不同材料的导线连接在两个接
Thermocouples are widely used as temperature sensing elements in data collection, equipment inspection, and industrial manufacturing. Its main advantages are low cost, long service life and measurement temperatures of up to several thousand degrees. In fact, thermocouples and non-contact infrared pyrometers are the only effective temperature measurement tools at temperatures up to 650 ° C. All of these features make the thermocouple has a wide range of applications in many fields. However, to truly make temperature measurement accurate, some basic guidelines must be followed and a certain understanding of its basic structure. When connecting two different material wires in two connections
