美國(guó)Granville-Phillips真空計(jì)控制器 GP 307真空計(jì)控制器
307系列真空計(jì)控制器（VGC）措施pressure, and utilizes pressure-related outputs to control a variety壓力，利用壓力相關(guān)的輸出控制各種of vacuum system functions and processes. To fi t a wide range of真空系統(tǒng)的功能和流程。以適應(yīng)廣泛的needs and applications, the 307 VGC is available in a variety of的需求和應(yīng)用，307 VGC在各種可confi gurations and prices. In its simplest form the 307 VGC runs結(jié)構(gòu)配置和價(jià)格。在其zui簡(jiǎn)單的形式307 VGC運(yùn)行a single ionization gauge (IG) in the range from 1 x 10-10 to 1 x一個(gè)單一的電離規(guī)（IG）的范圍從1×10-10 1 x10-1 Torr. With available modules the 307 controls four gauges,10-1乇。與現(xiàn)有的模塊307控制四個(gè)真空計(jì)，measuring pressure from 2 x 10-11 Torr to atmosphere, and six測(cè)量從2×10-11乇壓力的氣氛，和六process control setpoints.過(guò)程控制的設(shè)定值。
