用于气体的质量流量控制器（MFC）/仪表（MFM）8741型有两种型号：MFC / MFM型8741标准型：带工业以太网或模拟接口，适用于各种应用。 MFC / MFM型8741büS/ CANopen：适用于现有CANopen网络，以及工业以太网或现场总线网络与ME43型现场总线网关的集成。第二种选择是专为具有多个控制回路的应用而开发的。一个现场总线网关最多可连接32个MFC / MFM。 ME43型将基于CANopen的内部通信（称为büS：具有扩展功能的CANopen）转换为工业以太网和现场总线的行业标准。质量流量控制器/仪表始终可以在büS和CANopen通讯之间切换。 8741型可配置为MFM或MFC。可选，最多可校准四种不同的气体。热MEMS传感器直接位于气流中，因此可以达到非常快的响应时间。直动式比例阀作为调节单元，可确保高灵敏度。集成的PI控制器可确保MFC / MFM的出色控制特性。 8741型专门设计用于橱柜。

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
