用于气体的质量流量控制器/仪表8746型适用于büS或CANopen网络。 büS网络技术基于CAN物理，由Bürkert开发，特别适用于具有多个控制回路的应用中的工业以太网或现场总线通信。结合系统控制单元（SCU）类型ME2X，基于CANopen的通信可以转换为客户的现场总线。质量流量控制器（MFC）/仪表（MFM）始终可以在büS和CANopen通讯之间切换。鉴于此，8746型也可以直接集成到现有的CANopen网络中。 8746型可配置为MFM或MFC。可选，可以校准四种不同的气体。热在线传感器直接位于主气流中，因此响应时间非常快。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。 8746型特别设计用于恶劣环境，因为它对污染的敏感性低，防护等级高，防爆。 MFC 8746型有两种型号：带电磁阀或电机驱动的比例阀。

• 标称流量范围为20 lN / min至2500 lN / min

• 高精度和可重复性

• 基于CANopen的现场总线通讯

• 可选：ATEX II Cat。 3G / d

• 可提供电磁和电动阀门驱动

Type Description

The mass flow controller / meter Type 8746 for gases is intended for the use in a büS or CANopen network. The büS network technology is based on CAN physics and was developed by Bürkert especially for Industrial Ethernet or fieldbus communication in applications with multiple control loops. In combination with the system control unit (SCU) Type ME2X, the CANopen based communication can be translated to the customer’s fieldbus. The mass flow controller (MFC) / meter (MFM) can always be switched between büS and CANopen communication. Given that, Type 8746 can also be directly integrated into existing CANopen networks. Type 8746 can be configured as MFM or MFC. Optional, four different gases can be calibrated. The thermal inline sensor is located directly in the main 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 8746 is especially designed for use in harsh environments due to a low sensitivity to contamination, high protection class and explosion-proof. MFC Type 8746 is available in two versions: With electromagnetic or with motor-driven proportional valve.
