用于气体的质量流量控制器/仪表8742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ME2X型系统控制单元（SCU），可以将基于CANopen的通信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，8742型也可以直接集成到现有的CANopen网络中。 8742型可配置为MFM或MFC。可选，可以校准两种不同的气体。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。 8742型特别设计用于恶劣环境，具有高防护等级和防爆性能。

• 标称流量范围为0.010 lN / min至160 lN / min

• 高精度和可重复性

• 防护等级IP65和IP67

• 基于CANopen的现场总线通讯

• 可选：ATEX II Kat.3 G / d

Type Description

The mass flow controller / meter type 8742 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 8742 can also be directly integrated into existing CANopen networks. Type 8742 can be configured as MFM or MFC. Optional, two 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 8742 is especially designed for use in harsh environments due to high protection class and explosion-proof.
