类型 8626 - Mass Flow Controller for Gases (MFC)

类型描述

The mass flow controller (MFC) type 8626 is suited for regulating the mass flow of high gas flows. The thermal inline sensor is located directly in the gas stream and therefore reaches very fast response times. A direct-acting proportional valve from Bürkert guarantees a high sensitivity. The integrated PI controller ensures outstanding control characteristics of the MFC. Type 8626 can optionally be calibrated for two different gases; the user can switch between these two gases. As electrical interfaces both, analog standard signals and fieldbuses are available. The mass flow controller type 8626 is especially designed for use in harsh environments due to a low sensitivity to contamination and the high protection class. The MFC fits for various applications, like e.g. burner controls, heat treatment, metallurgy, food and beverage industry, environmental technology, material coatings, fuel cell technology or test benches.

（1）Nominal flow ranges from 20 lN/min up to 1500 lN/min

（2）High accuracy and repeatability

（3）Short settling times

（4）Protection class IP65

（5）Optional: Fieldbus interface
