型號(hào)描述

型號(hào) 8710 是一臺(tái)用于調(diào)節(jié)侵蝕性氣體質(zhì)量流量的裝置，它需要一個(gè)與介質(zhì)相分離的傳感器。在數(shù)字的電子調(diào)節(jié)設(shè)備中，會(huì)將傳感器提供的實(shí)際值與通過標(biāo)準(zhǔn)信號(hào)或現(xiàn)場(chǎng)總線規(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。這樣一來，就可以將質(zhì)量流量保持在一個(gè)確定的數(shù)值上，或使其遵循規(guī)定的曲線輪廓，而不會(huì)受到壓力波動(dòng)或設(shè)備中其他變化的影響。一個(gè)無摩擦工作的比例閥作為調(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，在熱處理、冶煉處理、環(huán)境技術(shù)、材料涂層以及燃料電池技術(shù)中進(jìn)行氣體計(jì)量或配制混合氣體。

1）采用毛細(xì)管技術(shù)的旁通裝置，適合額定流量范圍 5 mlN/min 至 10 lN/min
2）適合侵蝕性氣體
3）現(xiàn)場(chǎng)總線選項(xiàng)

Type Description

The mass flow controller (MFC) Type 8710 is especially suited for regulating the mass flow of aggressive gases, which need a sensor which is not in direct contact with the gas. The thermal capillary sensor reaches fast response times. A direct-acting proportional valve from Bürkert guarantees a high sensitivity. The integrated PI controller ensures outstanding control characteristics of the MFC. Type 8710 can optionally be calibrated for two different gases; the user can switch between these two gases. As electrical interfaces both, analog standard signals and fieldbuses are available.

1）Nominal flow ranges from 0.005 lN/min to 15 lN/min
2）High accuracy and repeatability
3）Applicable for aggressive gases
4）Optional: Fieldbus interface
