Vibration Meter

The Worldsensing Vibration Meter is a wireless 3-axis MEMS accelerometer designed for continuous, long-term vibration monitoring in construction, tunneling, and infrastructure environments. With a sampling rate of up to 1000 Hz derived from a 4k Hz signal, it delivers high-precision vibration measurements. Its built-in edge algorithm detects threshold breaches for vibration-based events using LAW/PPV and frequency, ensuring accurate and timely alerts.
Offering up to 1.5 years of battery life and extended communication ranges underground, the Vibration Meter provides a reliable for vibration monitoring.

Key features

Two operational modes (PPV and MTVV) provide processed vibration data that complies with the majority of vibration regulations
Configurable thresholds and reporting periods using both CMT or the Worldsensing App
Alert mode uses the secondary threshold to have highly critical events reported automatically in a shorter reporting period
Waveform data of events exceeding the alert threshold is stored in the device’s internal memory
Great communication ranges underground, with up to 10 km using repeaters
Compatible with Worldsensing’s single-net and multi-net configurations

Applications

Monitor the impact of vibrations created by industrial activities
Monitor the impact of industrial activities on surrounding infrastructure
