Burkert 267030 (00267030)

Mass flow controller

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

SPECIFICATIONS:

Mass Flow Controllers Type 8626 are compact arrangement that inspection the mass flow of gases. They control the set flow velocity nonetheless of hurdle including pressure drops or interim resistance to flow. Flow regulator include a flow meter, an electronic module, as well as a proportional valve. Inline sensors function in the CTA mode (constant temperature anemometers). In this case, the electrical thermal resist and the measuring resistance are set to a constant temperature difference. Both resistances are directly in the gas stream; three more resistances are outside him. All resistances are combined in an electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is constantly heated to maintain a clearly defined surplus temperature relative to the temperature of thefluid. Due to the reality that the resistances are situated directly in the channel, the apparatus have splendid dynamics: the response time when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
