Thông tin sản phẩm

Bronkhorst® model F-230MI Mass Flow Controllers (MFCs) are suited for accurate measurement and control of flow ranges between 0,2…10 mln/min and 10…500 mln/min with an operating pressure up to 400 bar and max. 400 bar pressure difference (ΔP). 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.

High accuracy, excellent repeatability
Fast response
Operating pressure / delta-P up to 400 bar
Compact, rugged design (IP65, dust and waterproof)
