Product Description The GMS-750RS is a measuring instrument designed specifically to measure the rotor-stator gap in large power generators. It is based on Kaman’s proven eddy current technology used for position/displacement sensing. Included with the GMS-750RS are: Wall Transformer 15Vdc Power Supply, and Insertion Depth Stops. The digital display reads the measured gap in inches over the calibrated span of 0.250” to 0.750”, with 0.001” resolution.

The calibration of the GMS-750RS is a 3 point calibration. The electronics will be taught the spring deflection using the 3 Calibration Plates. To calibrate, remove Insertion Depth Stops. Place the Base Plate with the two threaded guide pins on a workbench or other suitable level surface with guide pins facing up. Set the GMS-750RS on the Base Plate between the guide pins. The center (length and width) of the lower spring should be aligned the two guide pins. Place the .
