智能差壓變送器用于防止管道中的介質(zhì)直接進(jìn)入變送器里，感壓膜片與變送器之間靠注滿流體的毛細(xì)管連接起來(lái)。用于測(cè)量液體、氣體或蒸汽的液位、密度、壓力、以及流量，然后將其轉(zhuǎn)變成4～20 mADC電流信號(hào)輸出。它可以通過(guò)HART通訊協(xié)議的手操器相互通訊，進(jìn)行設(shè)定和監(jiān)控。
差壓式變送器適用于下述測(cè)控情況：
在石油化工生產(chǎn)過(guò)程中，智能差壓變送器經(jīng)常用來(lái)與節(jié)流裝置配合測(cè)量液體、蒸汽和氣體流量，或用來(lái)測(cè)量液位、液體分界面及差壓等參數(shù)。
二、性能規(guī)格
