VS138X Product and Test Capacity
VS138X is a handheld acoustic imaging camera for gas leaks and electrical partial discharge inspections.138 MEMS microphones collected 2-100 kHz sound signals, which were superseded with 13 million pixels visible images, to help operators locate abnormal sources from live images.A body less than 1 kg is suitable for mobile patrols and multiple inspections.
The built-in laser range allows for the recording of target distances, and leakage loss estimates, PRPD classification and spectrum analysis are used to further understand detection signals.The instrument supports off-line analysis and reporting, which is accompanied by photographic, video, voice and text labelling, and keeps the location of the equipment, detection conditions and anomalies in the same field record.

Core functions
Designed for physical testing
The key capabilities that affect the efficiency of on-site testing are centralized in a testing platform.
138 Channel Acoustic Array
Acoustic location is superseded to visible light images using 138 MEMS microphones to collect sound signals.
Wideband Filter
Adjust detection bands within 2-100 kHz to help distinguish target acoustic sources from background noise.
Leak analysis
Support for leak detection and loss estimates could form the basis for the maintenance ranking, for example, in combination with on-site pressure.
partial discharge analysis
Provides PRPD analysis and cutting-edge, along-line, suspended electricity and noise classification information to assist subsequent diagnosis.
Laser ranging
Inline 0.1-20 m laser ranging to record target distance and assist with detection settings.
Review and reporting on board
Support for acoustic data analysis, photo video playback and processing of test reports, offline.
Multi-form record
Text, voice, images and labels can be added to facilitate association equipment, location and unusual records.
Wireless and power supply
Double-frequency Wi-Fi, Bluetooth and USB are available to support Type-C PD and base charging.
Typical application
Compressed air leak
(c) Positioning the ultrasound sources in the interface, hoses, valves and pipes and recording the state of maintenance before and after maintenance.
Electrical partial discharge
The acoustic positioning of switch equipment, insulation components and connection locations was performed, and PRPD information was reviewed.
Petrochemical and process industries
Checking the leaking sources of valves, Frank and accessable pipes, and identifying problems in conjunction with field work.
Mechanical acoustic screening
The preservation of audio records is used for subsequent analysis through the abnormal acoustic area of the audio superheavy positioning device.
