Abstract
A sensor system for sensing contaminants within a fluid stream of a fluid system includes a sensor body and an arm extending from the sensor body to a distal end of the arm, a laser light source configured to direct a laser beam outwardly from an outlet of the sensor body, and a light sensor. A fiber optic light guide is disposed in the sensor body and extends from the light sensor to an inlet of the sensor body for directing light to the light sensor. A beam dump is positioned at the distal end opposite the laser light source to absorb at least a portion of the laser beam directed towards the distal end. A blocking member of the arm is disposed intermediate between the sensor body and the distal end and is configured to partially restrict a field of intake of light at the inlet.
