適用于真空、腐蝕性和研磨性介質(zhì)
優(yōu)良的重復(fù)性和*穩(wěn)定性
通過(guò) IEC 61508 和 IEC 61511認(rèn)證,適用于SIL2功能安全系統(tǒng)過(guò)程壓力監(jiān)測(cè)。
簡(jiǎn)單安全的菜單引導(dǎo)式操作模式:可使用現(xiàn)場(chǎng)顯示模塊進(jìn)行操作;或通過(guò)4-20 mA HART、PROF
IBUS PA、 FOUNDATION Fieldbus通訊方式遠(yuǎn)程操作。
模塊化設(shè)計(jì),測(cè)量差壓、靜壓和壓力(Deltabar M - Deltapilot M - Cerabar M)。如,可更換的
顯示模塊和主電子模塊。
無(wú)縫、獨(dú)立的系統(tǒng)集成(HART/PA/FF)
