INCLINOMETERS AND PRECISION LEVELS

Irrespective of whether they are spirit or electronic inclinometers, all precision levels are
based on the same perfectly reliable reference but also cost-free: the centre of the earth's
gravity.

Under the force of gravity, the gas bubble in the liquid or the pendulum inclines itself accor-
ding to this natural physical principle.

The position of the pendulum with respect to the measuring faces of the instrument body
can then be measured. Based on this perfect principle, these instruments offer a great nu-
mber of measuring applications of high precision. The horizontal and vertical positioning of
the measuring faces enable the detection of form errors in the geometrical elements on the
workpiece to be measured.
These errors often result from deviations in straightness, flatness, position, parallelism and
squareness.

Indication of values may vary depending on the type of level, the values typically displayed
are:
- inclination (mm/m or in/10 in);
- radian in mrad;
- decimal angle (e.g. 12,37°);
- sexagesimal angle in degrees (°), minutes (’) and seconds (”) e.g. 15° 30’ 45”.
