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.

7. OPERATIO N

In contrast to conventional hand-held
instruments, the WS09 does not have
a keypad instead it uses a simple
“thumb-wheel”, on the left-hand side
of the unit.

The wheel can rotate 15° upwards and
downwards and also be pressed in while in
the upper, lower or centre position.

The upper menu is selected by rotating
the wheel upwards. The lower menu for
configuration and calibration is selected
by rotating the wheel downwards.

The thumb-wheel must be pressed in the centre position to
switch the instrument on and off and to confirm input values.

7.1 The 3 positions of the THUMB-WHEEL:

Switch on: press briefly
Switch on backlight: press and hold for

approx. 2 seconds
Switch off: press and hold for approx.

2 seconds (in normal mode - no menu
activated)

Press briefly (in normal mode - no
menu activated): clear MIN/MAX
memory.

Activate upper menu with HOLD MAX

and calibration Selection with ,
enter with and interrupt with or
by not pressing the thumb-wheel for
20 seconds.

7.2 The upper menu
The following functions can be selected in the

upper menu:

HOLD MAX MIN AVG
Selection with , the selected

function flashes and is
entered with . An entered
function display is steady.

The menu can be interrupted
with or by not pressing the
thumb wheel for 20 seconds.

HOLD: Hold “freezes” the

measurement value.

MAX: MAX shows the

maximum value in the active
time period.

MIN: MIN shows the

minimum value in the active
time period.

AVG: AVG shows the arithmetical average value in the

active time period. The MAX value/MIN value/AVG
memory is cleared by switching the WS09 ON/OFF,
by disconnecting and reconnecting the sensor, or by
briefly pressing in normal mode.

3. PROBE INSTALLATION

The sensor probe connects to the WS09 box with a threaded
connector.

The probe should be inserted into the test fluid so that the
probe tip is completely immersed in the fluid. To decrease
stabilization time the fluid should be flowing or the probe
should be stirred in the fluid to create a flow past the sensor
element. Allow about three minutes for the reading to stabilize
before taking the measurement.
