Burkert 239037 (00239037)

Mass flow controller

The thermal inline sensor is located directly in the gas stream and therefore achieves very fast response times.

Burkert Type 8626 Mass Flow Controllers (MFC) are compact devices that control the mass flow rate of gases. They command the set flow rate nonetheless of obstruction such as pressure loss or provisional resistance to flow. Flow controllers include a flow meter, an electronic module, as well as a proportional valve. Inline sensors function in the constant temperature anemometers mode. In that event, the electrical heating resistance and the measuring resistance are set to a constant temperature difference. Both resistances are directly in the gas stream; and three resistances are out of it. All resistances are combined in an electrical bridge. The first resistance is gauge the temperature of the fluid. The second, low resistance, is heated continuously to sustain an expressly specified surplus temperature relative to the fluid temperature. Due to the reality that the resistances are disposed directly in the channel, the apparatus have superb dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
