VS138XH Product and Test Capacity
VS138XH integrates acoustic imaging, infrared thermal imaging, visible light and laser ranging into handheld equipment.138 MEMS microphones covering 2-100 kHz bands showing the location of the target ‘ s acoustic sources, such as leaks or discharges, on the scene;640 x 512 Infrared Explorer supplements temperature distribution information to allow for the inspection of equipment from both sound and heat angles.
The instrument supports leakage analysis, PRPD partial discharge analysis, spectrum and time frequency analysis, and allows for the preservation of photographs, videos and various forms of labelling.The site can use point, line, area and temperature differential analysis to review heat anomalies and then combine sound, distance and work-collating detection records for compressed air systems, electrical equipment and process industry inspections.

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Acoustic location is superseded to visible light images using 138 MEMS microphones to collect sound signals.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.
infrared thermal imaging Integration
640 x 512 Infrared Detector support points, lines, areas, temperature differential analysis and temperature alerts.
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.
Test Process
