As well as the standard measurement tasks*, the following route-
specific measurement tasks can be included:
Adaptive measurement task
An adaptive measurement task automatically adapts the sequence of
the route to the condition of the machines. If these run within the
permissible range, the data collector only records overall values. This
keeps the resulting volume of data and number of measurement tasks
to a minimum.
If an overall value exceeds the selected warning or alarm level,
additional diagnosis measurements are automatically performed.
These additional measurement tasks (spectrum, overall values) are
stored in the OMNITREND PC software for each machine and are
only called up if the operating condition of the machine changes.
The threshold value which triggers the diagnosis measurement is
defined in the OMNITREND software as an 'adaptive trigger'. If no
'adaptive trigger' is defined, the diagnosis measurement is trig-
gered when the lowest threshold value is exceeded.
Visual inspection
A visual inspection task includes all types of data gathering that are
based on defined conditions of a machine and that cannot be
measured with electrical signals. For example, the degree of contam-
ination of an aggregate, the belt tension on a drive or the fill level of a
tank can all be ascertained without having to measure a signal. The
possible conditions in OMNITREND are defined in the form of a
‘visual inspection task’ (e.g. ‘Aggregate clean / slightly contaminated
/ heavily contaminated’). The machine condition is inspected in situ
and the applicable option selected from a list.
Manual entry
This measurement task allows numerical measurement values that
were acquired from another measurement device or read on a display
instrument (e.g. flow rate, pressure,...) to be entered in VIBXPERT.
