Data are also subject to a light processing in real time calculating a leak proabability index.

Features

In this configuration ALD equipment includes an acoustic sensor to be fixed to vehicle shell and a POD to be integrated in the vehicle payload. Data are acquired and recorded during the run. A partial data  analysis is done in real time while the complete processing will take place after vehicle  recovery.
