In-line Moisture measurement of hydraulic, lubricating
oils and fuels.
EESIFLO’s EASZ-1 moisture meter measures
both moisture and free water i.e true water content
in almost any oil whether mineral or synthetic.
The unit has a resolution of 100ppm and a response
time of 1 second. The measurement does not stop
at the saturation point of the oil, it continues
working despite the saturation properties of the
oil. It has been designed with both the preventative
maintenance in mind as well as immediate alert when
a problem has occurred. The EASZ-1 is a loop powered
, temperature compensated highly developed permittivity
probe. Former dielectric or devices had the inherent
problem of drift due to poorly designed electronics,
many of them being analog devices where card recalibration
is necessary. This problem has been solved by using
digital processing and high quality manufactured
electronic circuits and sensor cells.
The EASZ-1 cell/transmitter will monitor and report
true water content in an oil. The measurement technique
offers the the end user then benefits of measuring
both moisture build up and free water. The outcome
is total water reporting. Nothing will be missed
with a response time of 1 second which we believe
should be the new benchmark for sampling response
time for water in oil measuring.
Online monitoring allows for real time preventative
maintenance or action. Some critical devices of
high value need to know when a problem has occurred
immediately when it has happened, not only when
a problem is probable. The EASZ-1 will instantly
give data on both situations . Water can enter hydraulic
and lubrication systems or fuels by atmospheric
ingression of water vapour, leaks or failing water
removal systems. The systems need to be checked
on a regular basis through spot sampling methods
and laboratory confirmation through Karl Fischer
analysis but the time between sampling periods can
be hours and even days or weeks. The EASZ-1’s
is continually sampling your process oil once a
second for water contamination in any form. The
EASZ-1’s sensor cell is not a probe but a
cell where the process oil is being sensed over
a large volume area with a response time of 1 second.
As part of our commitment to providing quality
products, each EASZ-1 water in oil transmitter is
electronically calibrated and tested to perform
within certain tolerances. Much care is taken during
assembly and testing to ensure that each EASZ-1
that leaves production will work to within its specifications.
Water contamination of hydraulic and lubricating
oils can cause serious damage to bearings and other
lubricated components - often without the equipment
user being aware that damage is occurring. Accountability
and online monitoring are essential to the success
of a well thought out water removal plan.
Left unchecked, these problems can rapidly lead
to costly breakdowns. The speed with which water-induced
degradation can progress, means that in many applications,
water contamination of the oil is a more serious
threat to equipment reliability than wear metal
contamination!
EESIFLO's EASZ-1 water in oil analyzer provides
early warning of any increase in water content so
that corrective action can be taken. Its response
time is one second and has a resolution of 100ppm
and a range from 0 -10,000 ppm, 0-1%, 0-3%, 0-10%
and 0-25%.
RS-485 is optional and the EESIFLO development
team are working on a HART protocol addition.
