Vibration Meter

Worldsensing Vibration Meter is a wireless sensor that automates data collection for long term, continuous vibration monitoring. It features a tri-axial accelerometer and an exception-based, edge algorithm that allows the detection of threshold breaches for vibration-based parameters such as LAW/PPV and frequency.

High precision 3-axis MEMS accelerometer. Up to 1000 Hz derived from a 4k Hz signal
Configurable operational modes to address different regulatory standards
Up to 1.5 years battery lifespan using a 30 min reporting period, considering a vibration scenario with relevant events triggering alert mode two or three times per week.
Great communication ranges underground, with up to 10 km using repeaters
Compatible with Worldsensing’s single-net and multi-net configurations

Description
Specifications

Long-range and low-power

The Vibration Meter is a robust, IP68 device, and can operate under minimum maintenance. It transmits data via long-range radio to a gateway up to 15 km/9 miles aways. Using a 30 minutes reporting period with events occurring at 2-3 minutes.

Enhanced vibrations monitoring

The Vibration Meter can be a complement to an existing highsensitivity vibration monitoring system. It allows you to increase the data density to detect isolated events, thus increasing the reliability of the entire system, it can last up to 1.5 years without battery replacements.

Easy and Efficient Network Management

One Worldsensing Gateway can support hundreds of Worldsensing edge devices in the same network that are also measuring other sensors installed in the monitoring sections. Worldsensing edge devices can also be easily configured and connected with a USB cable and an Android phone. The device network can also be easily managed through the Connectivity Management Tool.
