Bürkert Mass Flow Controller for Gases (MFC) Type 8710

The mass flow controller (MFC) Type 8710 is suitable for controlling aggressive gases, gas mixtures and applications with alternating gases. A thermal capillary sensor, with non-wetted sensor elements, is used for this. The forms in contact with medium are made of high-quality stainless steel and FFKM as seal material for high chemical resistance. Type 8710 can optionally be calibrated for two different gases; the user can switch between these two gases. The MFC achieves high control accuracy thanks to the use of Bürkert proportional valve technology, the application-appropriate layout of the valve orifice and the integrated PI controller. The MFC can be implemented with low pressure loss as required, due to the diversity of the available valve orifices. As electrical interfaces both, analogue standard signals and fieldbuses are available.
