一、概要在中温测量领域里,珠状玻璃密封式热敏电阻在国外早已广为应用。但国内产品因其稳定性和互换性欠佳,至今未能普遍采用。七十年代由于生产工艺的进步和国防工业的需要,元件的稳定性已大为提高。我们对国产元件的稳定性进行了一些试验,现将情况介绍如下。 First, a summary In the field of temperature measurement, bead glass sealed thermistor has long been widely used in foreign countries. However, due to their poor stability and interchangeability, domestic products have not been widely adopted so far. Seventies Due to the progress of production technology and the needs of the defense industry, the stability of components has been greatly improved. We made some experiments on the stability of domestic components, the situation is as follows.
