The NDU system is intrinsic safe. So, it can be operated also in potentially explosive environments. The housing is either weatherproof (IP 65) or explosion - proof. Data transfer to the computer is done by optical fibre transmission lines which allow up to 1500 m distance between sensorhead and the evaluation PC.

The first system was installed at Hoechst AG in 1995, the next were installed in 1996 / 97. They have has proved their supervision capability, and in addition, some alternative materials have been screened for future plant design.
