Application Matrix

One product category, multiple industrial use cases.

Acoustic cameras are used where faults create sound before they become visible. They help engineers turn ultrasonic emissions into visual evidence for inspection, maintenance and safety decisions.

Power & Grid Locate partial discharge, corona, tracking and abnormal sound sources in substations, switchgear and transmission assets.

Oil, Gas & Chemical Locate pressurized gas leaks, verify methane and support LDAR inspection in hazardous industrial environments.

Data Centers Inspect electrical rooms, switchgear, cooling equipment and cable routes for discharge, leaks and abnormal acoustic patterns.

Manufacturing Find compressed air leaks, mechanical noise and abnormal product sound sources in production and maintenance areas.

Mining & Heavy Industry Inspect conveyors, motors, fans, pumps and heavy equipment in high-noise and harsh operating environments.

Robotic Inspection Integrate acoustic modules with robots, fixed platforms or unmanned patrol systems for remote inspection workflows.

FAQ

Acoustic Imaging Camera FAQ

Common questions about acoustic cameras for gas leak detection, partial discharge inspection, methane verification, thermal imaging and fixed online monitoring.

What is an acoustic imaging camera?

An acoustic imaging camera uses a microphone array to locate sound sources and display them as a visual sound map. It helps engineers find invisible faults such as gas leaks, partial discharge and abnormal mechanical noise.

What can HERTZINNO acoustic cameras detect?

HERTZINNO acoustic cameras can help detect pressurized gas leaks, compressed air leaks, partial discharge, corona, tracking, mechanical noise, abnormal equipment sound and methane-related leak risks depending on the selected model.

How do I choose between HA3, HA3T and HA3LX?

Choose HA3 for general acoustic inspection, HA3T when thermal verification is also required, and HA3LX when methane verification is needed in oil, gas or chemical environments.

When should I use a fixed online acoustic camera?

Fixed online acoustic cameras are suitable for unmanned substations, compressor stations, data center electrical rooms, hazardous industrial zones and other sites that need continuous monitoring instead of periodic manual inspection.

Can acoustic cameras work in noisy industrial environments?

Yes. Acoustic cameras analyze frequency features and directional sound sources rather than relying only on audible sound. Models and settings should be selected based on background noise, target frequency range and inspection distance.

Which industries use acoustic imaging cameras?

Common industries include power grids, substations, oil and gas facilities, chemical plants, data centers, manufacturing lines, mining operations, hydrogen systems and critical infrastructure sites.

Key Applications & Demos

Partial Discharge Detection

Precisely locate PD sources (±15cm) from 200m away. Automatically classifies discharge types (Corona, Surface, Internal) and assesses severity using PRPD mapping to prevent failures.

Gas Leak & Cost Analysis

Detects leaks in Compressed Air, Hydrogen, SF6, and Natural Gas (20-100 kHz). Built-in AI estimates leakage volume and calculates annual energy loss costs in real-time.

Mechanical Fault Diagnosis

Visualize sound maps to identify bearing damage, blade imbalance, and misalignment in motors and fans. Pinpoints the exact location of faults to shorten troubleshooting time.
