INFICON 皮拉尼儀表增強(qiáng)型 500 (PGE500) 采用的數(shù)字對(duì)流增強(qiáng)型皮拉尼技術(shù)。由于對(duì)流的物理性質(zhì),這種皮拉尼型產(chǎn)品在 100 至 1000 mbar 的測(cè)量范圍中可達(dá)到更高的準(zhǔn)確度。堅(jiān)固的儀表和傳感器設(shè)計(jì)結(jié)合多種工廠內(nèi)置功能,例如明亮、流暢而清晰的 OLED 顯示器及集成鍵盤、RS485/RS232 數(shù)字接口和 4 種可選模擬輸出信號(hào),使得 PGE500 成為高價(jià)值/低擁有成本的選擇。所有這些特點(diǎn)使該儀表適合眾多需要低真空度至高真空度范圍的經(jīng)濟(jì)型真空測(cè)量功能的應(yīng)用。
