Type 8741 - Mass Flow Controller (MFC)/ Mass Flow Meter (MFM) for Gases

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 in combination with the system control unit (SCU) of type ME2X for büS networks. The second option was especially developed for applications with multiple control loops. The büS network technology is based on CAN physics. Up to 32 MFC / MFM can be connected to one SCU. One functionality of the SCU is the translation of the internal, CANopen based communication 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.
