4000 Series Air Gap Sensor System

The 4000 Series Air Gap Sensor System provides monitoring and diagnostic capability for all new and existing hydro generators and motor/generators, and fully integrates with the 3500/46M Hydro Monitor and System 1* software.

Air gap is a measure of the distance between the rotor and stator in a hydro generator. Monitoring the air gap is critically important because both the stator and the rotor on hydro machines can be flexible and their shape and location are affected by operating centrifugal, thermal and magnetic forces.
