2.4. Use as Agreed
The device Patrick is an optical particle monitor that may be used for the monitoring of fluid
cleanliness. It works according to the light extinction principle and detects particles and other
contaminants in the fluid. The measured values are calculated into purity classes according to
ISO4406:99 or SAE AS4059E and then shown on the display.
You may read the measuring data via a serial interface and transfer them to a measuring instrument
or a computer. The connection to the fluid system is achieved by two Minimess®test points of the
1620 screw series.
Any other use of this device is regarded as improper use. Please contact our service staff if you
have questions or want to use the device for another purpose. We will be always glad to help you.

3. Description of the Device
3.1. Qualities
The device Patrick is an optical particle monitor working according to the light-extinction principle:
Pic. 1 Functional principle
The device comprises a through-flown measuring cell (A), a laser (B) and a photo cell (C). The laser
shines through the measuring cell and impacts the photo cell. If a particle flows through the laser
beam, the intensity reflected by the photo cell is reduced. The larger the particle, the more the
reflection will be reduced.

You may use Patrick to monitor the contamination level and the purity trend of fluids. There may be
differences in the absolute accuracy to particle counters calibrated according to ISO 11171:99, but
this difference is smaller than one ordinal number. Changes are display with very high accuracy. By
the continuous purity monitoring you can detect changes within a machine very quickly. This allows
you to initiate measures to avoid further contaminations and damage to the machine.
The purity class display can be switched to ISO4406:99 or SAE AS4059E. The device also
measures the temperature, not in the liquid but on the electronic switchboard (measuring range -20
… 100 °C). The device is equipped with an operating counter, the values will still be available after a
power loss. After each interruption, the counter will restart at the last saved time value before the
interruption.

Minimess®hoses will be connected here to connect Patrick to the fluid system.
Display (2) (5)
The front panel may be rotated by 190° to allow a horizontal orientation of the display in any
mounting situation. The bw-display shows the last calculated purity classes and the time to the next
measurement, or the remaining measuring duration.

4. Installation and Start-up
4.1. Installation Location
Please observe these hints when choosing an installation location:
• Connect Patrick with a T-branch to a bypass pressure line.
• The flow direction is arbitrary.
• There should be constant pressure conditions at the installation location. The pressure may vary,
but there may not be pressure peaks or large alternations.
• It is recommended to choose a control line, otherwise you may also choose the filter or cooling
loop.
• The volume flow rate should be constant between 50 and 400 ml/min.
• Flow control or pressure reduction should be installed after the particle counter since such
installations may cause particles or air bubbles that may cause wrong measurements.
• If a pump is required to produce the required volume flow rate, it should be low-pulsating and be
installed in front of the particle counter. Otherwise bubbles could be generated on the suction
side what would lead to wrong measurements.

4.2. Installation
Please observe these hints before starting the installation:
• Assure that the display can be read easily after installation. It is rotatable by 190° to ease the
selection of a installation location.
• The shorter, the better is valid for connection hoses. If the hoses get too long, larger particles
may deposit.
• It must be assured especially for higher viscosities and the use of Minimess®hoses that the
pressure is high enough to set a volume flow rate between 50 and 400 ml/min.
• Assure a bubble-free fluid. Bubbles in the fluid result in very high ordinal numbers in different size
classes. Such bubbles cannot be visible to the naked eye.
Estimation of the required pressure level
Obtain the deltaP of the particle counter dependant to the fluid viscosity:
Pic. 4 ∆p-Q-curve for different viscosities
This diagram allows you to estimate the required pressure level for the required volume flow rate of
50 to 400 ml/min.
Installation
Now you may install Patrick:
1. Identify the installation location corresponding to the stipulated criteria.
2. Connect two fluid lines to the Minimess®test points.
3. Mount the particle counter using the mounting points at the rearside of the device.
