Burkert - Model Type 8626 - Mass Flow Controller
The Type 8626 mass flow controller forms an integrated system, consisting of the flow sensor, control electronics and control valve. Using this controller, mass flows of gases can be kept constant or can follow a predefined set-point profile regardless of interfering influences (such as pressure or temperature variations). The sensor works according to the thermal principle (constant-temperature anemometer). The measurement is made in the main channel and provides the mass flow directly without any corrections.
The digital flow controller compares the set point with the actual value and calculates the control signal for the proportional valve. The direct-acting solenoid control valve works according to the well-tried plunger-type principle, and is driven by a PWM voltage signal. Besides its control function an intelligent algorithm ensures that the valve closes tight with 0% set point. The measurement in the main flow of the MFC Type 8626 is characterized by an excellent dynamics and a low sensitivity to contamination. The MFC can be used in versatile flow control tasks.
