Abstract:
A debris detecting apparatus is provided which collects debris from a fluid system in a screen member and measures the accumulation of debris by measuring the change of inductance in a coil surrounding a portion of the screen member. A bridge detection means is used which includes the inductive coil as one leg of the bridge. A second sensor in the fluid connected as a second leg of the bridge provides temperature compensation for the bridge. The bridge is excited with a high frequency voltage at or near the resonant frequency of the sensing coil.

Abstract:
Apparatus is disclosed for detecting the presence of the type of debris in a fluid system. The apparatus detects the presence of debris, measures the accumulation and identifies the specific types of the debris. A plurality of sensors, connected in a bridge detecting circuit, are assembled in the apparatus in the fluid flow, each of said sensors are tuned to a specific preselected frequency which is characteristic of one material type of the debris. A variable frequency power supply is connected to the detecting bridge for exciting the bridge. Switching means are provided external to the detecting apparatus for selecting one of said sensors as the detecting leg of the bridge. When the sensor has been selected, the bridge is excited at the resonant frequency of the selected sensor for identifying a specific material type of the debris.
