c. Proximity to potential source of oil mist
A Sensor should be placed downstream of the airflow around a potential source
of oil mist (e.g. hydraulic pump). The closer the Sensor is to the machinery, the
faster the response time should be.
d. Number of potential sources of oil mist
A fourth factor is the number of potential sources of oil mist. To make it easier
to determine the source of oil mist, each piece of machinery or potential oil mist
source should have a Sensor installed immediately down-stream of the airflow to
ensure the fastest response possible.
In an engine room several Sensors are needed but the exact location will vary according
to airflow.

Direction of movement of air
Direction of movement of air as part of an eddy.
Location of Detector
EDDY 1 does not require monitoring as it up stream of the
potential oil mist source
Location of Detector in EDDY 2 is recommended as oil mist may
be drawn away from the vent.
