Dwyer 316濕濕差壓變送器 655A系列

量程可低至3英寸水柱,NIST溯源6點(diǎn)校準(zhǔn)

655A系列316L不銹鋼液用微差壓變送器用于高靜壓場(chǎng)合的微差壓監(jiān)測(cè),特別適用于OEM設(shè)備,它能在過(guò)壓非常高的情況下用于低至3英寸水柱的量程范圍,精度達(dá)到0.25%。

655A系列變送器采用了先進(jìn)的科技來(lái)保證高低壓口的平衡。自動(dòng)焊接制造技術(shù)使它在承受很高的壓力的應(yīng)用場(chǎng)合可靠耐用,壽命長(zhǎng)。每個(gè)產(chǎn)品都帶有NIST六點(diǎn)校準(zhǔn)證書。

655A系列微差壓變送器是全焊接的316不銹鋼材質(zhì),在設(shè)計(jì)中沒(méi)有采用任何O型環(huán),特別適用于高靜壓應(yīng)用場(chǎng)合,和保證不能泄露的應(yīng)用場(chǎng)合。
