Acoustic Monitoring Solution

Industrial Acoustic Monitoring for Valve Leakage & Pressurized Systems

Detect internal seat pass-through, micro-fissure leakage, and steam trap failures by isolating wideband acoustic audio emissions (20 Hz to 20 kHz) from background mechanical vibration.

What is Measured?

  • 1. Audio Acoustic Bandwidth: Precision acoustic audio sensing from 20 Hz to 20 kHz.
  • 2. Fluid Turbulence Noise: Micro-leakage creates distinct acoustic audio vortex shedding signatures.
  • 3. Kurtosis & Energy Envelope: Onboard DSP computes continuous kurtosis and signal energy density every 250ms.
  • 4. Operating State Baseline: Machine valve open/closed state is compared to establish true anomalous bypass.

Recommended Sensor Platforms

Both the Mercury Z1 Inline Sensor (direct threaded/clamp mount) and IGFO-100 Edge Node (magnetic probe mount) support 20 Hz – 20 kHz acoustic audio capture with Single Pair Ethernet (SPE) or BLE wireless telemetry.
