Abstract
A sensor installable within a gas turbine engine for sensing electrostatic charge therein. The sensor comprises a sensing plate and first and second shielding plates. The sensing plate has a first face with a first peripheral portion, and a second face with a second peripheral portion. The first and second shielding plates are spaced from and positioned relative to the first and second faces of the sensing plate, respectively, by a layer of electrically insulating material, so that electrostatic charge in the proximity of the sensor is sensed by both the first and second peripheral portions of the sensing plate.
Claims6
A sensor for sensing electrostatic charge, said sensor comprising:
- a sensing plate having a first face with a first peripheral portion, and a second face with a second peripheral portion;
- and
- a first shielding plate positioned relative to said first face of said sensing plate so that electrostatic charge in the proximity of said sensor is sensed by said first peripheral portion of said sensing plate.
