VS128N Acoustic Imaging Camera
Large-screen 10-inch, 2–65 kHz acoustic imaging for leak localization and abnormal equipment-noise screening.
Steady-state and transient algorithms
Select algorithms for continuous leakage or intermittent sounds to support screening under different conditions.Ultrasonic detection band
A 2–65 kHz range supports acoustic localization with band selection appropriate to the target signal.Partial-discharge analysis
PRPD information supports further review alongside source location and equipment condition.DESIGNED FOR INSPECTION
VS128N inspection capabilities
VS128N uses a two-hand, large-screen form factor with a MEMS microphone array to overlay sound-source distributions on visible images. Its 2–65 kHz operating band and steady-state/transient algorithms support screening for continuous leaks and intermittent abnormal sounds. The 10-inch touchscreen supports field viewing and shared review.
PRPD analysis, sound-map recording and playback support surveys of compressed-air pipes, valves, flanges and electrical equipment. An aluminum housing, IP56 protection and a specified six-hour single-battery runtime support field use. Optional external USB sensors can add sound-level or vibration information.

KEY FEATURES
Designed for real inspection work
The capabilities that matter in the field are brought together in one inspection platform.
Visible sound localization
Convert array signals into sound maps overlaid on the visible image to locate acoustic sources.
Steady-state and transient algorithms
Select algorithms for continuous leakage or intermittent sounds to support screening under different conditions.
Ultrasonic detection band
A 2–65 kHz range supports acoustic localization with band selection appropriate to the target signal.
Partial-discharge analysis
PRPD information supports further review alongside source location and equipment condition.
10-inch touchscreen
A large touchscreen supports sound-map viewing, setting adjustment and record playback.
Field protection
An aluminum housing and IP56 protection combine with two-hand operation for field work.
Power for extended surveys
A specified six-hour single-battery runtime supports route-based inspection tasks.
External sensor expansion
USB expansion supports sound-level or vibration sensors; confirm compatibility with the chosen configuration.
Typical applications
Compressed-air leaks
Locate ultrasonic leak sources at fittings, hoses, valves and pipes, then document conditions before and after repair.
Electrical partial discharge
Localize acoustic emissions around switchgear, insulation and connections, using PRPD information for further review.
Petrochemical and process facilities
Inspect valves, flanges and accessible pipelines for leak sound sources and correlate findings with operating conditions.
Mechanical noise investigation
Use sound-map overlays to locate abnormal noise regions and save records for subsequent analysis.
