Burkert 252914 (00252914)

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 succinct devices that inspection the mass flow rate of gases. They control the set flow velocity nonetheless of obstruction such as drop in pressure or provisional resistance to flow. Flow regulator include a flow meter, an electronic module, and a proportional valve. Inline sensors operate in the CTA mode (constant temperature anemometers). In this case, the electrical heating resist 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 joined in an electric bridge. The first resistance is measures the temperature of the fluid. The second, low resistance, is constantly heated to sustain a clearly specified excess temperature relative to the temperature of theliquid. Owing to the fact that the resistances are located straight away in the channel, the apparatus have excellent dynamics: the time for reaction when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not polluted.
