5.1.4 Description of the functions
Using the online particle monitor, the level of contamination and the purity trend of
fluids can be monitored. In this connection, differences as compared to particle
monitors calibrated according to ISO 11171:99 may occur with regard to the abso-
lute accuracy. The difference is, however, smaller than an ordinal number. Changes
are displayed in a very precise manner.
Due to the permanent monitoring of the purity, changes in the machine can be
detected very quickly. Due to the fast warning, measures can be taken without any
further serious contamination and thus possible damaging of the entire system.
Depending on the application conditions, Hengst recommends calibration every
two years.
The online particle monitor also measures the temperature. It is not measured in the
oil but on the electronic circuit board.
The online particle monitor has an operating hours counter the values of which are
also available after current interruptions. After the interruption, the counter re-starts
counting at the last stored time value before the interruption.
