Features

The Pall WS09 Series water sensor is a hand held, monitoring
solution for measuring dissolved water content in hydraulic,
lubricating and insulating fluids. Specifically designed for use
in harsh and often remote industrial environments, readings
are continuously displayed on the hand-held display as a
key component in the predictive maintenance of plant
and machinery.

• A sensing probe directly immersed in the fluid to monitor

dissolved Water content and temperature

• Water content displayed in % saturation or PPM

• Temperature displayed in °C or °F.

GENERAL

The manual is a part of the scope of supply and serves
to ensure proper handling and optimum function of the
instrument. For this reason, the manual must be read
before start-up.
In addition, the manual is for all personnel who require
knowledge concerning transport, setup, operation,
maintenance and repair. The manual must not be used for
the purpose of competition without a written consent from
Pall and must also not be forwarded to third parties.
Copies for personal use are permitted.
All information, technical data and illustrations contained in
these instructions are based on information available at the
time of publication.

WARNINGS, CAUTIONS AND NOTES

Care must be taken in referring to this manual to ensure
adherence with all warnings, cautions and important notes.
These carry information related to the safety of personnel and
the integrity and satisfactory operation of plant.

Safety instructions

General Safety Instructions

• Excessive mechanical loads and incorrect usage

should always be avoided.

• Do not remove the filter cap as the sensor element

could be damaged.

• Installation, electrical connection, maintenance and

commissioning should be performed by qualified
personnel only.

Environmental aspects

At the end of its life, the monitor should be dismantled
and disposed of in accordance with all applicable local
waste disposal laws and bylaws. Where facilities exist,
component parts of the unit may be recycled. Details of
the materials of construction are given on the product
installation drawing and, if required, more detailed
information regarding specific items may be obtained
from Pall or an approved agent.
In Europe under the Waste Electrical and Electronic
Equipment (WEEE) Directive and implementing
regulations, when customers buy new electrical and
electronic equipment from Pall they are entitled to:
Send old equipment for recycling on a one-for-one,
like-for-like basis (this varies depending on the country).
The customer is also entitled to send the new equipment
back for recycling when this ultimately becomes waste.
Instructions to both customers and recyclers/treatment
facilities wishing to obtain disassembly information are
provided by following the link below.
www.pall.com/weee
If component parts of the equipment were previously
contaminated with the service fluid, an appropriate
Manufacturer’s Safety Data Sheet (MSDS) for the
fluid should be obtained and read to ensure that
contaminated component parts are disposed
of safely.

1. INTRODUCTIO N

The Pall WS09 Hand Held Water sensor was designed for the
measurement of water content in hydraulic, lubricating and
insulating fluids. Percentage saturation and temperature is
measured by immersing the sensing probe into the fluid
stream, reservoir or fluid sample. After a short stabilization
period the WS09 LCD displays the percentage water saturation
level and temperature in °C or °F. The probe is suitable for use
in a wide range of mineral and synthetic fluids at temperatures
up to 120 °C (248 °F). The WS09 transmitter features
outstanding long term stability and resistance to pollution of
the capacitive sensor elements.
Water contamination in oil and fluids can cause problems such
as additive depletion, corrosion, oil oxidation, reduced
lubricating film thickness, microbial growth and a reduction of
dielectric strength.
Humidity measurement in oil is similar to the humidity
measurement in the air; the actual water content in oil can be
indicated by the relative value % RH.
% RH (expression of the water content as a percentage of the
water saturation level of the oil at the measured temperature)
and called percent relative humidity. % RH = 0 corresponds
to completely water-free oil, while % RH = 100 indicates
saturated oil. Saturation is the point where oil holds as
much water as possible in solution at given temperature,
any further addition of water will result in the presence of
droplets of free water.
The physical quantities measured are % relative humidity,
% RH, and temperature, T. With these quantities the Pall WS09
Water sensor can calculate, and display, the water content in
parts per million (ppm), provided that the fluid constants for the
specific fluid have been entered into the unit.
The WS09 is capable of displaying two outputs at one time.
These outputs are shown on the display as sensor 1 and
sensor 2. Sensor 1 is set to temperature and sensor 2 is set to
% relative humidity as default. The display may be changed
using the menu function. For example sensor 1 can be set to
either °C or °F temperature and sensor 2 can be set to either
% relative humidity (% saturation) or water content in PPM.
Calculation of water content in fluids can be accomplished by
entering specific fluid constants for the fluid; contact Pall for
the fluid constants.
