Abstract
A chip detection system for an engine fluid system includes an emitter located in a first position proximate to a fluid passage of the engine fluid system, the emitter including a radioactive source that generates ionizing radiation particles and transmits the ionizing radiation particles through a liquid within the fluid passage. A detector includes a detecting element located in a second position relative to the fluid passage with the liquid disposed between the emitter and the detector. The detecting element generates an electric current in response to the ionizing radiation particles contacting the detector. A controller is in communication with the detector to receive the electric current generated by the detecting element. The controller is operable to detect chips in the liquid when the electric current generated by the detecting element is greater than a threshold value of the electric current.
