Since the rotor and the stator must be matched as closely as possible to achieve the highest efficiency, the dimension of the rotor must also be inspected. The Gagemaker T-MIC and MM line of gages provide exactly what is needed to obtain the dimensions necessary. The T-MIC gages measure the crest to crest dimension of the rotor and the MM gages inspect the valley to valley dimension. With this data, the size of the rotor is easily determined and therefore can be perfectly matched with its stator.
