Designed as a maintenance tool for measuring rotor-stator gap in large scale power generation applications, the GMS-750RS rotor-stator gap measuring system from the Measuring Division of Kaman Precision Products, Inc., uses the company’s proven eddy current sensor technology. Incorporated into an easy to calibrate turnkey instrument, the sensing tool provides accurate and repeatable gap measurements between 0.250 and 1.000 inch, with a 0.001-inch resolution. The eddy current technology senses the distance between the two leaf-type springs that are compressed together when inserted between a rotor and stator. The sensing system provides an LED readout of the gap in inches or millimeters.
