Electronic combusible gas mixer reduces
costs
An electronic gas mixing and dosing system with CMos sensors, regulates the supply to a burner or any other consumer with gas mixtures consisting of two or more gases.
Witt Gas Witt Gas Techniques, the Warrington, Cheshire based gas safety, control, mixing and analysis equipment supplier has launched the MDE electronic gas mixing and dosing system with CMos sensors, which regulates the supply to a burner or any other consumer with gas mixtures consisting of two or more gases When used in the manufacture and forming of glass it helps reduce costs

System delivers gases, air, power from one point
From one central point, a modular energy compact system provides services such as Acetylene, Oxygen, CO2, Argon, shielding gas as well as compressed and fresh air, vacuum and electricity.
For each product change, the burner supply for separating, shaping, tempering, flame polishing, burling or rounding must be set individually for each product.
This means that the mass flow of burnable gases must be adjusted and disturbances such as primary pressure fluctuations, burner changes and temperature influences must be counterbalances.
With the MDE series this is different.
This system uses 'MFC' (mass flow controller) technology, which not only keeps set-up times to a minimum, but also supplies digital measurement data to ensure a consistent quality control.
Unlike analogue control engineering, the control electronics developed by Witt Gas Techniques ensures exact reproducibility of any process parameter once it has been ascertained.
The deviations do not exceed 0.5% of the final scale value.
In terms of its control characteristics, The MDE series reaches the required target values in less than 0.3 seconds, using an auto-calibration function to ensure a rapid, accurate flow rate.
This control function keeps values stable throughout the production cycle.
The integrated digital RS-485 bus system allows remote control from a PC on the series interface, PLC machine control or the AWE/AWS evaluation systems available from WITT Gas Techniques.
The MDE series delivers a continuous data flow from the sensor to the control unit so that specific operating parameters can be ascertained and monitored.
The consumption levels of individual gasses can also be accurately recorded.
MFC technology combines all components required for the burner supply in a single device.
It is easy to install, as backflow valves, filters and solenoid valves are fully integrated into the MDE series.
With an integrated flame non-return finger, the MDE series meets the strictest safety requirements.
