类型 8711 - Mass Flow Controller for Gases (MFC)
类型描述
The mass flow controller (MFC) Type 8711 is suited for regulating the mass flow of gases over a big flow range. The thermal MEMS 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 8711 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 8711 fits for various applications, like e.g. burner controls, heat treatment, material coatings, bio reactors, fuel cell technology or test benches.
（1）Nominal flow ranges from 0.010 lN/min to 80 lN/min
（2）High accuracy and repeatability
（3）Very fast settling times
（4）Optional: Fieldbus interface
