Internal AntennaAutomated Vibration Monitoring for Infrastructure Safety
The Wireless Vibration Meter is a tri-axial sensor built for long-term, continuous vibration monitoring of bridges, tunnels, buildings, and industrial assets. It leverages an exception-based edge algorithm that automatically detects and reports threshold breaches based on PPV and frequency parameters.
Available with internal antenna (Vibration-IR) for compact, streamlined deployment in general assessment applications.
PPV-based & MTVV-based operation
Automatic threshold breach alerts
Waveform capture for post-event analysis
Wireless configuration via Worldsensing App
Two Powerful Analysis Modes
Configurable operational modes with advanced algorithms for various vibration standards and assessment requirements. Available with internal antenna for compact deployment.
PPV-Based Mode
Reports Peak Particle Velocity (PPVx,y,z in mm/s), frequency (fx,y,z in Hz), temperature (ºC), and Peak Vector Sum (PVS). Velocity range: 0-60 mm/s (±0.01 mm/s). Frequency output range: 1-100 Hz (±0.5 Hz). Ideal for blast vibration monitoring and structural response assessment.
MTVV-Based Mode
Reports maximum transient vibration value (LAW-x,y,z in dBm) and temperature (ºC). Acceleration range: ±2g. Frequency weighting: Wm. Designed for human comfort assessment and continuous vibration monitoring per ISO standards.
Alert mode with secondary threshold enables automatic reporting of critical events via real-time notifications.
What Makes the Vibration Meter Different
Purpose-built for automated structural and ground vibration monitoring with edge intelligence and long-range wireless connectivity.
High-Precision MEMS
3-axis MEMS accelerometer with 22.5 μg/√Hz noise floor (XHP). 1000 Hz sampling derived from 4 kHz signal for accurate vibration measurement across 0.5-250 Hz frequency band.
Long Battery Life
Up to 2 years of unattended operation on a single 3.6V D-size replaceable battery. Optimized power management with configurable reporting intervals from 10 minutes to 6 hours.
IP68 Rated & Rugged
Industrial-grade IP68 enclosure for full submersion protection. Operating range from −40°C to +80°C — suitable for the harshest field conditions.
Edge Algorithm
Exception-based detection automatically identifies threshold breaches based on PPV/LAW and frequency parameters, eliminating manual data retrieval and reducing false alarms.
Cloud & Edge Management
Configure locally via CMT Edge for single-network deployments, or connect to CMT Cloud for multi-project, multi-network oversight from anywhere.
Mobile App Configuration
Wireless Bluetooth setup via Worldsensing App. Includes integrated temperature and humidity sensors for comprehensive environmental monitoring.

It's a wireless tri-axial sensor for continuous vibration monitoring of structures like bridges, tunnels, railways, and buildings — helping detect vibration events, assess structural health, and ensure safety compliance.
The sensor uses a 3-axis MEMS accelerometer with an edge algorithm that identifies threshold breaches based on PPV/LAW and frequency, ensuring only critical vibration data is reported.
It supports LoRaWAN for long-range, low-power communication — up to 15 km range in open terrain. Configuration via Worldsensing App (Bluetooth) or remotely via CMT Edge and CMT Cloud.
With its ultra-low-power design, the replaceable D-size battery lasts up to 2 years under normal operation (30 min reporting, SF9), ensuring reliable long-term deployment.
PPV-based mode reports Peak Particle Velocity and frequency for blast and structural monitoring. MTVV-based mode computes maximum transient vibration values with Wm frequency weighting for human comfort assessment.
It can be installed on bridges, tunnels, buildings, industrial machinery, and construction sites — including underground or hard-to-reach locations, providing continuous vibration insights.
