Characteristics of the unit
The gear pump sucks the oil to be analyzed and funnels it to the
ContaminationSensor where the solid particles are detected by an optical
sensor, divided up into classes by size and counted.
Any air bubbles contained in the oil may skew the measurement results as
they, like particulate contamination, cause the measurement cell to generate
signals. For this reason, the powerpack is fitted with an air release line. Its
job is to suppress any existing air bubbles, within the realm of what is
technically possible, to such an extent that the measurement result is not
skewed or is only negligibly skewed.
The highest pressure possible in the ContaminationSensor is targeted as oil
with increasing pressure can release an increasing quantity of air (reference
value: approx. 8% air per bar). This is achieved using a valve situated
downstream of the CS.
However, pressurized air cannot be immediately dissolved in oil,
consequently a path is provided for between the pump and the sensor.
