AquaSensor
AS 3000
Description
The AquaSensor AS 3000 is the
further development of the proven
AS 1000 series for the online
detection of water in oils, particularly
as a sensor for condition monitoring.
It records the water saturation and the
temperature of the operating uid.
The display allows you to view the
current measured values or to adjust
the parameter settings.
The measured values are output as
a 4 ... 20 mA or 0 ... 10 V signal and
are the basis for two parameterisable
switching outputs.
The AS 3000 thus enables hydraulic
and lubricating oils to be monitored
accurately, continuously and online.
Applications
z Mobile hydraulics
z Hydraulic and lubrication systems in
industry
Advantages
z 4 digit digital display, can be aligned
in two axes
z User-friendly due to key
programming
z Individual conguration
z Reliable on account of its compact,
rugged design
z Economical sensor
z No calibration required for dierent
oil types
z Pressure-resistant, even with
pulsations
z Early detection of water problems
thus preventing faults and
unnecessary interruption to
operations
