1. GENERAL INTRODUCTION TO INCLINATION MEASUREMENT

1.1 HISTORY OF INCLINATION MEASUREMENT
Inclination measurement was used already in ancient times
• for the construction of buildings
• for the creation of simple city maps
• for navigation at sea
The use of new materials and working methods allowed the development
of new and more accurate inclination measuring instruments
• 1727 the first sextant was built according to Isaac Newton‘s
designs Sextant
• 1760 the first theodolite was made by the physicist Dollond

Sir Isaac NEWTON
1642 - 1727
Especially in the field of quality assurance, inclination measurement is applied in
various different forms
An inclination measuring instrument is used for:
• measuring an inclination
• measuring the straightness of a line, e.g. of a machine guideway
• measuring the flatness of a surface
• long-term monitoring of objects

The classic spirit level is increasingly being replaced by electronic inclination measuring instruments due
to higher requirements of precision, resolution, sampling time, reliability, data storage, and documenting.
The latest development clearly tends towards inclination measuring sensors bound in networks with the
possibility of data transmission over short and long distances and collected in appropriate units such as
computers and display units (Levelmeter, BlueMETER, BlueMETER SIGMA).

Classic precision spirit levels are increa-
singly being replaced by
modern electronic inclination
measuring instruments and sensors.
