Burkert 304427 (00304427)

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 rate nonetheless of interference including drop in pressure or provisional resistance to flow. Flow regulator consist of a flow meter, an electronic module, and a proportional valve. Inline sensors function in the CTA mode (constant temperature anemometers). In this case, the electrical heating resist and the measuring resistance are set to a constant temperature differentiation. Either resistances are immediately in the gas stream; and three resistances are out of it. All resistances are united in an electric bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is heated continuously to sustain a clearly defined excess temperature relative to the temperature of thefluid. Due to the fact that the resistances are located at once in the channel, the devices have superb dynamics: the response time when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not contaminated.
