由于国内市场均未见出售生产现场用真空校验装置,因此仪表使用厂对绝对压力变送器及其它真空测量仪表(以下统称为“真空仪表”)的现场校验,一直感到特别困难,尤其是使用真空仪表数量多的单位,这个矛盾更为突出。为此,我们设计制作了一台手提式真空校验仪,体积小,重量轻,性能稳定可靠,使用操作方便。在现场可同时校验两台真空仪表,不仅大大提高了工效,而且减轻了劳动强度,深受仪表工人的欢迎。
Since none of the domestic market has seen the use of vacuum gauges on production sites, it has been particularly difficult for gauges to use on-site verification of absolute pressure transmitters and other vacuum gauges (hereinafter collectively referred to as “vacuum gauges”), in particular Is the use of a large number of vacuum gauge units, this contradiction is even more prominent. To this end, we designed and manufactured a portable vacuum calibrator, small size, light weight, stable and reliable performance, easy to use. At the scene can be verified at the same time two vacuum gauges, not only greatly enhance the work efficiency, but also reduce the labor intensity, welcomed by instrumentation workers.
