TRIAXIAL ACCELEROMETER

The triaxial Accelerometer is able to measure the acceleration of the point where it is installed, which is essential for measuring the vibration frequencies and for carrying out a modal study of the structure.
With the use of Accelerometer devices it is possible to highlight any seismic vibrations and monitor its risk. With the interface of the Web Platform, it is possible to synchronize the acquisitions of each sensor, an optimal feature for dynamic load tests. All sensors also record temperature, are battery powered and use the LoRaWAN wireless communication protocol.

ACCELEROMETER OUTPUT
The Accelerometer acquires 10 seconds of data for each stress on the structure whenever the activation threshold
– previously set on the Web Platform – is exceeded. The measured acceleration values are expressed in mg.
The acquisition methods can be set by the user through the Web Platform provided with the Move SolutionsTM
monitoring system. It is possible to take advantage of an operating mode with programmed acquisition, with a fixed frequency set by the user, lasting 180 seconds. The device also acquires temperature data.

QUICK GUIDE TO USE
The triaxial Accelerometer device is “plug and play”; by screwing the special antenna on the cover, the device will immediately start to detect and try to send data to the Gateway device. To ensure correct operation the Accelerometer sensor must be correctly oriented and installed, following these specific steps:
1.
ORIENTATION:
•
The three axes shown on the orientation label, placed on the sensor cover, must be aligned as the axes of interest of the structure.
•
The Accelerometer device can be rotated freely on the structure.
2.
INSTALLATION ON THE STRUCTURE:
•
Agree with the supplier company on the correct place of installation on the structure of the Accelerometer device.
•
Firmly install the Accelerometer on the wall, ceiling or floor using the special plate and screws/wall plugs supplied. It is possible to rotate the plate relative to the device.
•
To install multiple Accelerometers on the same structure, use the same orientation convention, i.e. with the axes shown on the label of each specific device oriented in the same way.
•
Install all sensors on the structure before powering and turning on the Gateway device.
3.
SCREWING THE ANTENNA:
•
Before activating the Gateway, screw the LoRaWAN 868 Mhz antenna onto the device cover.
After meeting these orientation and installation requirements, the Accelerometer device will be able to detect and send data to the Gateway without interference or data alteration.
Verify, via the Web Platform, the correct functioning of the sensor just installed. From the moment the Gateway is powered up, and therefore from the actual start-up and activation moment, a maximum waiting of about an hour is required before it is possible to correctly view all the sensors online.
