PDF Instruction 1
The Hertzinno HZ-FA-371 is an advanced fixed acoustic imaging camera engineered for continuous 24/7 online monitoring of electrical partial discharge, compressed gas leaks, and mechanical noise anomalies. Equipped with a high-density 128-channel MEMS microphone array and sophisticated AI beamforming algorithms, this device precisely localizes sound sources and visualizes them over high-resolution video streams in real time across a distance of 0.3m to 50m.
Designed for demanding industrial infrastructure, the camera features robust explosion-proof certification Ex ib IIC T4 Gb / Ex ib IIIC T80°C Db and IP66/IP68 ingress protection. Seamless system integration with enterprise platforms and robotic systems is achieved through standard industrial interfaces including RTSP, HTTP, WebSocket, and Ethernet.
Scope of Application
- Continuous partial discharge and corona monitoring in high-voltage substations and switchgear rooms
- Automated gas leak localization across pipelines, valves, flanges, and compressor stations
- Compressed air leakage detection in automated manufacturing facilities
- Integration with unmanned patrol platforms and robotic inspection systems
- Acoustic monitoring of switchgear, UPS, and cooling zones in data centers
