Single Axis Vs Triaxial Data
Both single axis and triaxial data are valid depending upon the application and the type of faults one is looking for. Typically, even when single axis sensors are used, more than one axis is tested per bearing, but again it depends on the application. This can take more time as the sensor has to be moved more often and more tests have to be initiated in the data collector. Data is not collected simultaneously and the possibility exists that the machine can change state (load or speed) between tests or even shut down.
