LTG-LINK WIRELESS ACCELEROMETER
LTG-Link node is an accelerograph for structural health monitoring.
OVERVIEW
Description
The most innovative characteristic of the sensor is that it is completely wireless. The monitoring system is designed so that a central aggregator completely wirelessly synchronizes the nodes to UTC time and collects data.
HIGH PERFORMANCE
The on-board triaxial accelerometer allows high-resolution data acquisition with low noise (25 µg/√Hz) and low drift. Additionally, LTG-LINK node embeds a battery which is recharged by a small photovoltaic panel. In bad weather the node can keep on working for up to 30 days.
EASY TO USE
The Wireless Sensor Network (nodes and aggregator) enables simultaneous, high-speed sensing and data aggregation from scalable sensor networks.
Users can easily program nodes for continuous, periodic burst, or event-triggered sampling using the software included. The optional web-based cloud interface optimizes data aggregation, analysis, presentation, and alerts for sensor data from remote networks.
IDEAL FOR DIFFICULT TO ACCESS STRUCTURES WITH NO POWER
Our wireless sensing system is ideal for test and measurement and remote monitoring.
Application
Structures such as bridges have considerable oscillations that excite the structure and are devoid of energy sources needed to power any equipment.
In a scenario like this the LTG-Link is perfect.
Firstly, because the exciting signals have enough amplitude to be sensed with the right resolution by the 80dB MEMS accelerometer, secondly because the power supply autonomy overcomes the power supply issue.
Therefore a cable free and GNSS free system like this, simplifies the installation.
The maximum distance between an LTG-Link and a central station can be up to 2Km (in line of sight).
