Q: What is the difference between the HZ-FA-371 and the HZ-FA-371T?

The HZ-FA-371 is a dedicated fixed acoustic camera with 128 MEMS microphones for detecting partial discharge, gas leaks, and mechanical noise. The HZ-FA-371T adds a high-resolution thermal imaging module (640×512) to the same acoustic platform, enabling simultaneous acoustic and temperature anomaly detection for more comprehensive fault diagnostics.

Q: What types of faults can these acoustic cameras detect?

They are designed for three primary applications: Partial Discharge (PD) Detection: Identify and classify corona, floating, and surface discharges in high-voltage equipment. Gas Leak Detection: Locate pressurized gas leaks and estimate leak rate and potential financial loss. Mechanical Noise Monitoring: Detect abnormal sounds in rotating machinery for predictive maintenance.

Q: What is the detectable frequency range and distance?

The acoustic sensors cover a bandwidth of 2 kHz to 65 kHz, capturing both audible and ultrasonic signals. Depending on the source intensity and environmental conditions, the effective detection distance ranges from 0.3 meters up to 50 meters.

Q: What data outputs and integration protocols are supported?

The cameras support Ethernet/HTTP transmission, RTSP video streaming, and provide real-time data via HTTP/WebSocket for alerts and integration with SCADA, DCS, or third-party monitoring platforms.

Q: Does the device feature onboard processing (edge computing)?

Absolutely. The cameras perform real-time sound source localization and AI-based fault analysis directly on the device via edge computing. This minimizes latency, reduces network bandwidth usage, and enables instant alerts without relying on a central server.
