The GMS-750RS rotor-stator gap measuring system is suitable for measuring rotor-stator gap in large-scale power generation applications. Using the company’s current sensor technology, it provides accurate and repeatable gap measurements between 0.25 in. and 1 inch, with a 0.001-in. resolution. Promoted as being easy to use and featuring a simple design that eliminates operator variables, the system promises to reduce the overall time it takes to align the rotor to the stator. In operation, leaf-type springs compress together when inserted between a rotor and stator. The distance sensed is the distance between the two target springs. This concept ensures the eddy current sensor mounted in between sees a consistent target, ensuring maximum performance. Featuring a long insertion depth and adjustable insertion stops, the system provides an LED readout of the gap in inches or millimeters. For more information, go to
