Intermediate Gear Azimuth Sensor

A sensor, used in conjunction with a rotating shaft and a suitable phonic wheel, to provide an electrical ac signal whose frequency is an integer multiple of the shaft speed and whose phase is directly related to the shaft angular position. This signal is intended to be used as a timing pulse for vibration signal processing requiring speed-position synchronization. This allows the aircraft pilot to know the speed-position synchronization in the intermediate gearbox at any time during actuation.
