6.4 Tiltmeter Orientation
ORIENTATION LABEL
Before installing the device on the structure it is necessary to understand how to
correctly orient the axes shown on the orientation label located on the device cover.
The orientation label acts as an indicator of the direction in which the Tiltmeter de-
vice must be rotated and oriented. The label depicts the three Cartesian axes in re-
lation to the device, specifically with the X axis facing upwards and with the Z axis
coming out of the Tiltmeter cover.
SENSOR ORIENTATION
To correctly install the Tiltmeter device on the structure, make sure that the axes
shown on the device label are installed as indicated below:
•
The X axis as parallel as possible to the gravitational axis.
•
The X axis always oriented upwards.
•
The plane formed by the Y - Z axes parallel to the horizontal plane.
•
The relative axes of the device oriented as the absolute axes of the structure.
The orientation of the Tiltmeter device does not vary depending on where it is in-
stalled (wall, ceiling or floor). The X axis shown on the label must always be oriented
upwards, as parallel as possible to the gravitational axis and perpendicular to the
horizontal plane of the ground.

INSTALLATION ON THE STRUCTURE
To allow the Tiltmeter device to perform a correct measurement, it is necessary to
carry out an equally correct installation and orientation of the sensor.
Based on the context and the morphology of the structure, the Tiltmeter device can
be installed in any arrangement:
•
Rear or side wall installation.
•
Floor installation.
•
Ceiling installation.

IMPORTANT
•
The X axis shown on the label must always be oriented upwards, resul-
ting as parallel as possible to the gravitational axis and perpendicular
to the horizontal plane (i.e. the ground).
