Abstract : An arrangement of hot-wire anemometers is set partially into the rotor boundary layer so that they form two resistors of a wheatstone bridge circuit for each axis. The hot wire resistors change in resistance according to the angular offset from null of the gyro rotor. The combination of resistance changes in then used in the bridge circuit to provide an electrical signal which is directly proportional to gyro rotor angular offset. (Author)
