8741中文资料宝帝流体控制系统数据手册PDF规格书

The Type 8741 mass flow controller (MFC)/mass flow meter (MFM) for gases is

suitable for a variety of applications and is available with Industrial Ethernet, analogue

or fieldbus interfaces. The variant with CANopen-based Bürkert Systembus

(büS) is suitable for integration into existing CANopen networks or (in combination

with the Type ME43 fieldbus gateway) for integration into all common industry

standards for Industrial Ethernet and/or fieldbus. The latter option is tailor-made for

applications with many control loops. Up to 32 MFCs/MFMs can be connected to

one fieldbus gateway. Type ME43 transmits the internal CANopen-based communication

to Industrial Ethernet and fieldbus standards. The mass flow controller/

mass flow meter can always switch between büS and CANopen communication.

Type 8741 can be configured as an MFM or an MFC according to demand. Furthermore

a Modbus RTU variant is available as well. Optionally, up to four calibration

curves can be stored in the device. The thermal MEMS sensor is located directly in

the gas stream and therefore achieves very fast response times. As actuator, a

Bürkert direct-acting proportional valve guarantees high response sensitivity.
