LTG-Link Wireless Accelerometer

LTG-Link is a premium quality wireless triaxial 80dB accelerometer.

The only connectors available are the antenna and power supply, that’s because the units are synchronized via wireless signal.

A central station handles the synchronism between the units when it is less than 50μs and the sampling rate depends on the number of stations.

A monitoring system can have more than one central station, each central station manages communication and synchronism in its own subnet.

Each central station has its own GNSS receiver to get a fix on the time.

LTG-Link is supplied with a small photovoltaic panel that recharges the internal LiFePo4 battery thus the system is self powered

Bridges Monitoring

 

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).
