Straightness measurement is done on a large number of applications, for example
balks, rolls, machine constructions, transportation lines etc.
The basic principle for straightness measurement
The basic principle for straightness measurement is that all measurement values
will show the position of the detector unit relative the laser beam. To be able
to use the values for adjustment and documentation it is needed to set absolute
references (zero points). These can be points on the measured object or the
horizontal level.
Horizontal level
When using horizontal reference, the laser beam is levelled according to the
vials on the D22 laser transmitter. When the measured object is the reference,
the laser beam is levelled to the detector positioned at the reference points.
This levelling is always done according to the same principle: zero setting of
the laser.
Straightness measurement with S and M units
It is also possible to perform a straightness measurement with the S and M
units from a shaft alignment system (i.e. no separate laser transmitter is
needed). The S unit is used as reference transmitter and the M unit is used as
detector. In this case thou, it is not possible to use horizontal reference.
