The acoustic imager is an advanced sound‑visualization and positioning device for industrial use, mainly for pressurized gas leak detection and power‑system partial discharge inspection. With its built‑in data acquisition and processing module and beamforming technology, it captures real‑time acoustic signals from leaks or partial discharges and converts invisible sound into visual images for fast anomaly localization.

Its onboard system logs key inspection parameters such as sound intensity, leakage rate and partial‑discharge position. It provides real‑time acoustic analysis with single‑point positioning accuracy of ±3 mm, and supports auto‑analysis, photo/video capture and quick inspection‑report generation. Compatible PC software enables multi‑modal fusion of acoustic and infrared imaging.

Designed for routine and preventive maintenance, the instrument cuts equipment downtime and maintenance costs. Suited for sites with wide inspection coverage and many risk points, it greatly boosts inspection efficiency and operational safety for industry and power systems.

Product Advantages

● High detection efficiency

Through real-time imaging technology, the leak source is automatically located and visualized, greatly improving detection efficiency.

● High precision

Extremely high resolution, capable of detecting extremely small leaks, with a positioning error not exceeding ±3mm over a certain distance.

● Leakage Assessment

It can capture ultrasonic signals generated by leaks and combine them with data analysis to automatically assess the size of the leak.

● Partial Discharge Assessment

It can determine the type of partial discharge based on the ultrasonic signals generated by partial discharge, and can assess the intensity of partial discharge.

● Long testing distance

It can detect gas leaks and partial discharges (up to 150 meters) at a relatively long distance (up to 50 meters).

● Multi-sensor fusion

Multi-sensor fusion technology can maintain high detection efficiency even under more complex conditions.

● High screen resolution

The 8-inch display with a 1280*800 resolution provides a more intuitive visual experience.

● Strong anti-interference capability

Advanced ultrasonic processing technology suppresses ambient noise to capture leak‑specific frequency signals for accurate detection.
