Mass Flow Controllers Type 8626 are succinct arrangement that monitoring the mass flow rate of gases. They command the set flow rate regardless of hurdle for example drop in pressure or temporary flow resistance. Flow controllers consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors work in the constant temperature anemometers mode. In that event, the electrical heating resist and the measuring resistance are adjusted to a constant temperature differentiation. Both resistances are immediately in the gas stream; three more resistances are outside him. All resistances are joined in an electrical bridge. The first resistance is measures the temperature of the liquid. The second, low resistance, is constantly heated to maintain an expressly defined surplus temperature relative to the liquid temperature. Due to the fact that the resistances are inclined directly in the channel, the devices have excellent dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not contaminated.
