Bürkert 是流體控制系統(tǒng)的全球供應(yīng)商，具有70年的流體控制經(jīng)驗(yàn)， 在德國(guó)和法國(guó)擁有多個(gè)研發(fā)中心和生產(chǎn)廠，并在35個(gè)國(guó)家和地區(qū)設(shè)有分公司。 Bürkert 產(chǎn)品與系統(tǒng)適用于對(duì)液體和氣體介質(zhì)進(jìn)行測(cè)量和控制，具備極廣泛的產(chǎn)品系列（包括電磁閥、過程控制閥、分析閥、氣動(dòng)執(zhí)行機(jī)構(gòu)、傳感器和控制器等）和解決方案，可對(duì)液位、流量、壓力、溫度和分析等參數(shù)進(jìn)行測(cè)量和控制。 Bürkert不僅為客戶提供單個(gè)的產(chǎn)品，我們的目標(biāo)是要為客戶提供滿足其實(shí)際應(yīng)用需求的解決方案和完整的系統(tǒng)。Bürkert可為客戶定制不同應(yīng)用領(lǐng)域的流體控制系統(tǒng)，如化學(xué)工業(yè)、水和污水處理、醫(yī)療設(shè)備、食品飲料行業(yè)、制藥行業(yè)和工業(yè)加工等。
用于氣體的質(zhì)量流量控制器（MFC）/儀表（MFM）8741型有兩種型號(hào)：MFC / MFM型8741標(biāo)準(zhǔn)型：帶工業(yè)以太網(wǎng)或模擬接口，適用于各種應(yīng)用。 MFC / MFM型8741büS/ CANopen：適用于現(xiàn)有CANopen網(wǎng)絡(luò)，以及工業(yè)以太網(wǎng)或現(xiàn)場(chǎng)總線網(wǎng)絡(luò)與ME43型現(xiàn)場(chǎng)總線網(wǎng)關(guān)的集成。第二種選擇是專為具有多個(gè)控制回路的應(yīng)用而開發(fā)的。一個(gè)現(xiàn)場(chǎng)總線網(wǎng)關(guān)最多可連接32個(gè)MFC / MFM。 ME43型將基于CANopen的內(nèi)部通信（稱為büS：具有擴(kuò)展功能的CANopen）轉(zhuǎn)換為工業(yè)以太網(wǎng)和現(xiàn)場(chǎng)總線的行業(yè)標(biāo)準(zhǔn)。質(zhì)量流量控制器/儀表始終可以在büS和CANopen通訊之間切換。 8741型可配置為MFM或MFC。可選，最多可校準(zhǔn)四種不同的氣體。熱MEMS傳感器直接位于氣流中，因此可以達(dá)到非?？斓捻憫?yīng)時(shí)間。直動(dòng)式比例閥作為調(diào)節(jié)單元，可確保高靈敏度。集成的PI控制器可確保MFC / MFM的出色控制特性。 8741型專門設(shè)計(jì)用于櫥柜。
Type Description
The mass flow controller (MFC) / meter (MFM) type 8741 for gases is available in two versions: MFC / MFM type 8741 Standard: with Industrial Ethernet or analog interface, suitable for a wide range of applications. MFC / MFM type 8741 büS / CANopen: suitable for the integration in existing CANopen networks, as well as Industrial Ethernet or fieldbus networks in combination with the fieldbus gateway of type ME43. The second option was especially developed for applications with multiple control loops. Up to 32 MFC / MFM can be connected to one fieldbus gateway. Type ME43 translates the internal CANopen based communication (called büS: CANopen with extended functionalities) to industry standards for both Industrial Ethernet and fieldbuses. The mass flow controller / meter can always be switched between büS and CANopen communication. Type 8741 can be configured as MFM or MFC. Optional, up to four different gases can be calibrated. The thermal MEMS sensor is located directly in the gas stream and therefore reaches very fast response times. A direct-acting proportional valve as regulating unit guarantees high sensitivity. The integrated PI controller ensures outstanding control characteristics of the MFC / MFM. Type 8741 is especially designed for use in cabinets.
Nominal flow ranges from 0.010 lN/min to 160 lN/min
High accuracy and repeatability
Very fast response times
Easy device exchange through configuration memory
Available in two versions: 8741 Standard and 8741 büS / CANopen
