Mass Flow Controller (MFC)/ Mass Flow Meter (MFM) for Gases
Type 8742 / Ident No. 311384
Product 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.
