摘要
热电阻温度计是一种基于电阻的热效应来测量温度的仪器,具有良好的测温稳定性,在中低温区温度测量中应用广泛。本文详细阐述了热电阻的三种接线方式,并根据其测温原理分析了不同接线方式的优缺点,最后对在实际应用中如何选型提供了建议。
Thermal resistance themlometer is a kind of instrument based on thermal effect of resistance to measure temperature. It has good temperature stability and is widely used in temperature measurement in low and medium temperature region. In this paper, three wiring modes of thermal resistance are described in detail, and the advantages and disadvantages of different wiring modes are analyzed according to their temperature measuring principle. Finally, some suggestions are given for practical application.
