Abstract
An annular absorbent filter element of a sensor probe is exposed to fluid while held by one end of a coil spring in contact with magnetic and non-magnetic discs non-conductively spaced from a third non-magnetic disc to supply a contamination signal to a two-stage detection circuit through which internal deterioration conditions of machinery are monitored. Electrically conductive and magnetic flux paths are established through the filter element and a flux gap to magnetically attract contaminants and establish parallel connected, variable resistances through which said contamination signal is derived. The signal output of the sensor probe thereby provides an early warning alert to prevent machinery damage.
