2.4 Principle of Operation
The sensor is based on the principals of Magnetometry to enclose the sample fluid in a magnetic field.
The sensor has two symmetrical measurement chambers: measure and reference halves. The
reference half is kept empty, whilst the measure half is filled with fluid sample. The sensor measures
the difference between the halves; the result is due to ferrous debris. This configuration results in
extremely temperature stable and repeatable measurements: both coils experience the same
environments and external influences.
Oil which may contain ferrous particles is supplied to the measure half; this is then emptied by an air
blast ‘flush’ to complete the reading. The sensor takes two readings per measurement: empty
chamber and full chamber. The reference half of the sensor has factory fitted blanking plugs – do not
remove. Contamination of this empty and sealed chamber may affect readings.
