Air gap monitoring of rotor in generator

In large generators and electric motors, certain imbalances during various operations are bound to occur. These imbalances could be the result of wear caused by extreme wind and weather conditions, which could cause the the rotor touch the stator. Hence, the gap between the stator and rotor, i.e. the air gap must always be maintained and kept consistent in ordor for the machine to work efficiently.

Capacitive displacement sensor capaNCDT from Bestech Australia is used for this non-contact measurement of  displacement, distance and position. These sensors are especially designed to perform such measurements that require reliability and temperature stability as in case of generators. These sensors are protected by a special housing and are resistant to vibration and magnetic fields.
