Features
The Pall WS10 Series water sensor is an in-line, 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 transmitted continuously to the user’s control system 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 output in % saturation
•High pressure option up to 100 bar (1450 psi)
•Two analogue outputs, 4–20 mA, for connections to existing
SCADA and DCS systems
GENERAL

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. PRODUCT DESCRIPTION
1.1 General
The Pall WS10 Water sensor was designed for the
measurement of water content in oil. WS10 is
used for online monitoring of moisture in
lubrication or insulation oil, which is very
important for the long-term performance and
preventive maintenance of plant and machinery.
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 (actual water content expressed as a
fraction of the water content in saturated oil) and
called percent relative humidity (% RH). % 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, any further addition of water will result
in the presence of droplets of free water. % RH
measurement with the WS10 transmitter is based
on the outstanding long term stability and
resistance to pollution of the capacitive sensor
elements.
The WS10 transmitter has two analogue outputs,
4–20mA, for connection to customers existing
SCADA and DCS systems. The analogue outputs
represent humidity in % RH, and temperature. If
oil is cloudy due to free water contamination at
the measurement temperature, the WS10 Water
Sensor will output a signal that represents 100 %
saturation, until steps are taken to bring the water
content below the saturation point.

5. MAINTENANCE
5.1 Sensor cleaning
Cleaning of the measuring head is recommended
before use with another fluid and prior to
calibration. Do not touch or rub the sensing
element during the cleaning process!
Cleaning of sensor from oil residue:
1) Immerse only the measuring head in
N-HEPTAN and swirl for approx. 30 seconds.
Do not use solvents such as acetone.
2) Remove excess liquid and allow to air dry for
approx. 2 minutes.
5.2 Self-diagnostic and error messages
LED D1 (blue):
- constantly lit => sensor element damaged
- flashing => sensor element bedewed (Wet with
free water)
6. ORDERING INFORMATION
3. INSTALLATION
3.1 Installation location
The Water Sensor enclosure is designed in
modular form for safe and convenient installation.
The M12 connector allows for electrical wiring of
the Water Sensor for power and sensor output.
Each section of the enclosure fits securely to
achieve at least IP65 moisture protection rating.
Select a location that offers optimum measuring
conditions, the oil must be representative of the
system as a whole and must be able to circulate
freely around the sensing element. Mount the
transmitter directly into the circulating system,
in a pipe that is always full of oil. Reservoir
mounting is not ideal unless the reservoir
residence time is short.
3.2 Installing the probe directly into the process
When installing a probe directly into the process,
there should be a stop valve on both sides of the
point of installation.
This makes it easy to remove the transmitter for
maintenance and calibration.
Step 1: Install the probe with the
stop valves closed.
It is not permitted to use a sealing
ring with a NPT 1/2" thread.
Appropriate PTFE sealing tape or
sealant should be used instead.
Step 2: Insert the probe into the
process and screw it as tight as
possible by hand.
Step 3: If there is a sealing ring,
check it for correct centering and
tighten the screw connection with
a torque of 30 Nm.
