Air Gap variations occur with the flexing or movement of the stator and rotor due to operating centrifugal forces, magnetic forces and thermal effects.
AGTracII – Air Gap Monitoring
The AGTracII and Capacitive Air Gap Sensor provides continuous monitoring of the air gap between the rotor and the stator winding on Hydro Generators.
Capacitive Air Gap Sensor
Capacitive Air Gap Sensors measure the distance between the rotor and stator in hydroelectric generators to avoid reduced efficiency or damage caused by off-center or out-of-round conditions.
