摘要 本文阐述SWINGWIRLⅡ电容式涡街流量计中所采用的差动开关电容基本结构原理,并对其抗振能力特别强这一性能特点进行详尽分析。 Abstract Starting from the basic structure principle of differential switch capacity,the feature of its strong vibration resistance are analyzed. Thus,the effect of noise interfernce prod.ced by process line vibration on flow meter is eliminated.Abstract
