随着国民经济的飞速发展,真空技术在各个领域得到更广泛的应用,同时对低真空的测量提出了越来越高的要求。为了适应低真空的准确测量,我们研制了几种性能稳定的新型热偶规管,其特点是:性能稳定,量程宽(10~(-1)～10~(-2)帕),结构紧凑小巧,适应性强。与传统的热偶规管DL—3相比,还具有反应快、抗氧化、抗污染、寿命长等优点。
With the rapid development of the national economy, vacuum technology has been widely used in various fields, and at the same time, higher and higher requirements have been put forward on the measurement of low vacuum. In order to meet the accurate measurement of low vacuum, we have developed several new thermocouples with stable performance, which are characterized by stable performance and wide range (10-1 to 10-2 Pa) Small, adaptable. Compared with the conventional thermocouple regulation DL-3, it also has the advantages of fast reaction, anti-oxidation, anti-pollution and long service life.
