Burkert 225117 (00225117)

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 are succinct devices that inspection the mass flow rate of gases. They command the set flow velocity irrespective of hurdle for example drop in pressure or interim flow resistance. Flow regulator include a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the constant temperature anemometers mode. In that event, the electrical heating resistance and the measuring resistance are set to a constant temperature difference. Either resistances are immediately in the gas stream; three more resistances are outside him. All resistances are joined 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 sustain an expressly defined excess temperature relative to the temperature of thefluid. Owing to the fact that the resistances are situated straight away in the channel, the devices have excellent dynamics: the response time when altering a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not contaminated.
