DGF-I1 Gas Density and Concentration Sensor

This case study illustrates how the DGF-I1 density sensor is used in welding machinery to monitor gas mixtures to ensure a strong weld seam.

For a strong weld seam, the gases used must be correctly mixed. However, mechanical valves can move and leaks or mix-ups can lead to the mixing ratio no longer being correct. Up to now, it has only been possible to check the gas used by means of random sampling. With the TrueDyne sensor, you can monitor the quality of your welding gas directly in the process. With the density data and with the help of tables and calculation algorithms, the concentration of the gases used can be precisely determined and reported to the customer.

monitoring gas mixtures in welding machinery

  1. Welding device.
  2. Gas mixer which mixes the gases used for welding.
  3. TrueDyne’s DGF-I1 density sensor measures the density of the gas mixture directly in the process. If this deviates from the nominal value, the process can be interrupted immediately.
  4. Thanks to the ongoing quality control of the gas used, you can weld without rejects.
