摘　　要：为节约工业铂热电阻铂金属的用量,作者介绍了采用覆铂一钯引线玻璃骨架工业铂热电阻元件的试制及其引线的物理性质、热电性能,并提供了抽测10支样品的测试结果。测试和实际应用证明,这种感温元件应用于550℃以下是没有问题的。In order to minimize the consumption of metallic Pt in producing industrial RTDs, the author introduces the development of an in- dustrial RTD with glass frame and Pt-Pd co- ated leads. The physical and thermoelectric proporties of the leads are introduced and the testing results of 10 samples are given. The testing data and practical applications show that these elements are suitable for tempera- ture up to 550℃.
