With more than 99% availability, Openair® Plasma systems offer our Plasmatreat customers the greatest process capability. Openair® Plasma nozzles can also be equipped with threefold process monitoring in order to respond quickly and effectively and prevent a system outage.
To ensure uniformly high plasma quality, the emergent plasma stream is spectrally monitored on a continuous basis. A sensor integrated into the plasma nozzle measures the light emitted by the plasma as part of a one-channel optical detection system. This is followed by a permanent amplitude evaluation in the relevant spectral range of the emitted light. This monitoring is independent of plasma generation and reliably describes the process parameters of the plasma.
Along with plasma intensity and effective distance, the travel and rotation speed of the plasma nozzles is an important criterion of treatment quality. The movement control systems available in Plasmatreat systems ensure reliable process runs and high production process reliability.
Control of the supply of media is indispensable to ensure reproducible process-specific plasma parameters (temperature and intensity). Plasmatreat offers monitoring units for every need, including a flow measuring device controlled by a micro-controller.
