CMP Features
The gear pump sucks the fluid to be analyzed and conveys it to the
ContaminationSensor, in which the particulate contamination is captured by an
optical sensor and analyzed according to particle size classifications and counted.
Any air bubbles contained in the fluid may skew the measurement results as they,
like particulate contamination, cause the measurement cell to generate signals.
The purpose of the CSM is to suppress air bubbles so that the measurement results
are not skewed or only minimally impacted.
Because fluid absorbs an increasing quantity of air as the pressure increases (rule
of thumb: ~ 8% air per bar), the ContaminationSensor aims to achieve the greatest
possible pressure. This is done using a downstream pressure relief valve.
However, pressurized air cannot be immediately dissolved in the fluid, consequently
a path is provided for between the pump and the sensor.
Restrictions pertaining to use
NOTICE
Impermissible operating media
The unit will be destroyed
►
The unit may only be used in combination with phosphate esters (HFD-R)
e.g. Skydrol, Hyjet.
NOTICE
Highly contaminated fluid
The pump will become worn out / damaged.
►
For long-term operation, pump only fluid with a maximum contamination of
ISO 22/20/18
