Triaxial Tiltmeter
6
The triaxial Tiltmeter is able to measure the variation of the static angular inclination
of the structure with respect to the horizontal plane, i.e. perpendicular to the gra-
vitational axis. By installing an entire system it is possible to reconstruct the static
deflection of the structure. All Tiltmeters can be perfectly synchronized with each
other, which is perfect for static load tests. The Tiltmeter is also able to measure
temperature. It is battery powered and has a LoRaWAN wireless transmission.
The data acquisition methods can be set by the user through the Move Cloud Pla-
tform™.
OUTPUT TILTMETER
The Tiltmeter outputs angles that describe the variation in inclination of the body
on which the device is installed. The calculation of these angles is based on the
projections of the gravity vector on the three axes of the sensor, averaged over an
acquisition interval of one minute. The sensor also acquires the temperature.
By installing an entire system it is possible to reconstruct the static deflection of the
structure during a load test.

6.1 Quick guide to use
The triaxial Tiltmeter device is “plug and play”; by screwing the special antenna on
the cover, the device will immediately start to detect and send data. To ensure cor-
rect operation, see the chapter “Tiltmeter Orientation” and “Tiltmeter Installation Gui-
de”, the Tiltmeter sensor must be correctly oriented and installed, following these
specific steps:
1.
ORIENTATION:
•
The axes shown on the orientation label, which is placed on the sensor
cover, must be aligned as the axes of interest of the structure.
•
The X axis must always be oriented upwards.
•
The X axis must be as parallel as possible to the gravitational axis.
•
The plane formed by the Y - Z axis must be parallel to the horizontal plane.
2.
INSTALLATION ON THE STRUCTURE:
•
Agree with the supplier company on the correct place of installation on
the structure of the Tiltmeter device.
•
Securely install the Tiltmeter on the wall, ceiling or floor using the special
plate and screws/wall plugs supplied. It is possible to rotate the plate re-
lative to the device to keep the X axis parallel to the gravitational axis and
oriented upwards, regardless of the agreed installation location.
•
To ensure correct installation, the X axis must have a maximum inclina-
tion of 85° with respect to the gravitation axis.
•
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 Tiltmeter device
will be able to detect and forward data to the Gateway without interference or data
alteration. Verify, through the Move Cloud 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.
