Thông tin sản phẩm

Bronkhorst® model F-200CI Mass Flow Controllers (MFCs) are suited for precise measurement of flow ranges between 0,014…0,7 mln/min and 0,6…9 mln/min with pressure rating between vacuum and 64 bar. The MFC consists of a thermal mass flow sensor, a precise control valve and a microprocessor based pc-board with signal and fieldbus conversion. As a function of a setpoint value, the flow controller swiftly adjusts the desired flow rate. The IN-FLOW model is of rugged design (IP65) for use in industrial environments or even Zone 2 hazardous areas, with optional ATEX Cat. 3 approval.

IN-FLOW series are equipped with a digital pc-board, offering high accuracy, excellent temperature stability and fast response. The main digital pc-board contains all of the general functions needed for measurement and control. In addition to the standard RS232 output the instruments also offer analog I/O. As an option, an on-board interface can be mounted to provide DeviceNet™, PROFIBUS DP, Modbus, or FLOW-BUS protocols.

Lowest gas flow rates
Compact design, small internal volume
High accuracy and repeatability
Virtually pressure and temperature independent
Rugged, weatherproof housing (IP65, dust and waterproof)
