7.1.7 TWO-DIMENSIONAL INCLINATION MEASUREMENT SENSORS ZEROMATIC

The two-dimensional inclination measurement sensors ZEROMATIC 2/1 and 2/2 are perfectly suited for
any application where monitoring of the smallest changes in absolute inclinations over a longer period of
time is required. The extremely high accuracy is achieved by measuring and
compensating for any drift of the absolute „zero“ by applying an automatic
reversal measurement at defined intervals.
The ZEROMATIC 2/2 has two inclination sensors. They can provide con-
tinuous values for the inclination in X and Y axes. At defined intervals it will
perform a reversal measurement and compensate for any offset.
The ZEROMATIC 2/1 has one inclination sensor. It can therefore only pro-
vide continuous values in either X or Y axis. At defined intervals it will perform
a reversal measurement and compensate for any offset. After such a reversal
measurement the sensor will provide one set of precise and absolute inclina-
tion values in the X and Y axes.

Typical applications are:
• Monitoring of critical machines
• Monitoring of buildings, bridges or dams
• Defining absolute zero references e.g. for radars
The instruments have the following features:
• High-precision mechanics for the automatic reversal measurement
• Measuring range ± 1°
• Display range ±5°
• Rugged precision aluminum housing for protection against external influences
• Internal sensors with HTR compensation
• LEDs showing the status of the instrument
• Data transmission to PC/laptop
• Optional connection to an external BlueMETER SIGMA display unit
