- Model AGAP - Air Gap Measuring Instrument



The AGAP system measures the distance between the stator and the rotor in the machine. Measurement and analysis of the measured results can provide wide range of problems related to alignment, core stability, pole stability, roundness of the rotor and stator, etc. Besides measurement and data analysis, AGAP system provides data storage in the database for data comparison and trending.
