Concentricity Alignment Tool

The Concentricity Alignment Tool (CAT) is used to concentrically align turbine diaphragms to the shaft of the turbine. (It is also known as Electronic Radial Alignment Gage or ERAG.) There are now three measuring heads available that cover the range of most turbines including some of the smaller marine turbines. The CAT is manufactured by EDS Measurement Systems, Inc. in Rochester, New York, USA.
