burkert8711氣體質(zhì)量流量調(diào)節(jié)高精度裝置
型號(hào) 8711 是一臺(tái)用于調(diào)節(jié)氣體質(zhì)量流量的裝置,適合工藝技術(shù)領(lǐng)域內(nèi)大多數(shù)的用途。在數(shù)字的電子調(diào)節(jié)設(shè)備中,會(huì)將以硅芯片為基礎(chǔ)的傳感器(參見第 2 頁(yè)的描述)提供的數(shù)值,與規(guī)定的額定值進(jìn)行比較;存在調(diào)節(jié)偏差時(shí),會(huì)通過一種 PI 調(diào)節(jié)算法對(duì)發(fā)送到比例閥上的調(diào)節(jié)參數(shù)進(jìn)行修改,由此補(bǔ)償調(diào)節(jié)偏差。因?yàn)閭鞲衅髦苯犹幱跉饬髦校詼y(cè)量反應(yīng)時(shí)間非常短。質(zhì)量流量可以保持在一個(gè)確定的數(shù)值上,或遵循規(guī)定的額定值曲線輪廓,而不會(huì)受到壓力波動(dòng)或設(shè)備中其他變化的影響。可針對(duì)兩種不同的氣體對(duì)型號(hào) 8711 進(jìn)行校準(zhǔn),用戶可在兩者之間進(jìn)行轉(zhuǎn)換。一個(gè)直動(dòng)式比例閥作為調(diào)節(jié)元件,確保了高反應(yīng)靈敏度和裝置良好的調(diào)節(jié)特性。典型的用途是,在以下領(lǐng)域中進(jìn)行氣體計(jì)量或配制混合氣體:試驗(yàn)臺(tái)、生物反應(yīng)堆、熱處理、材料涂層、燃燒器控制以及燃料電池技術(shù)。
