The invention described in this specification relates to apparatus for monitoring the intake of foreign bodies and objects into an engine, particularly a gas turbine engine whereby sensors are located at or near the engine intake for detecting any electrostatic charge induced on the sensors by the passage of foreign bodies therepast. The specification particularly discloses an arrangement for a gas turbine engine in which sensors are provided in the exhaust duct and in the inlet duct and that signals from sensors in the inlet duct and exhaust duct are compared and contrasted.
