NL Acoustic camera for Partial Discharge (90019000-P001)
The NL Camera PL001 is a smart acoustic device for locating:
• Leaks in compressed-air systems
• Partial discharge problems in high voltage electrical systems
The NL Camera automatically locates leaks or partial discharges by the sound that they emit, even in loud industrial environments. It is lightweight,
easy to use and offers industry leading performance.
The 124 microphones of NL Camera allow detection in a wide field of view and from extended
range. This helps identifying problems up to 10 times faster than with traditional methods. The located
leaks or partial discharges are instantly superimposed on the camera view allowing the user to pinpoint and report leaks visually.
Leaks or partial discharges are analyzed in real time utilizing the built-in processing power. Collected information and images can be uploaded to
NL Cloud service for deeper analysis and reporting.

NL Camera Viewer is an offline computer
software alternative to the NL Cloud used for viewing and analyzing the snapshots taken with the NL Camera.
The offline software expands your sound imaging experience by offering various analysis methods for the sound image and the signal.
When using the leak version of the camera, the software analyzes leak sizes and leak costs.
When using the PD version, the software shows the PD pattern.
