Triax accelerometer kit

SKF’s triax accelerometer quickly and automatically measures horizontal, vertical and axial (triaxial) data with the press of a button Triaxial measurements offer the user additional information on the condition of machinery, enabling a more complete diagnostic analysis For example, measuring in a vertical direction often provides insight into how the shaft is restrained when considering bearing looseness A horizontal orientation is preferred for bearing fault diagnosis and an axial measurement can provide clues as to the severity of shaft misalignment.

The SKF Microlog can acquire data simultaneously from all three axes The triax accelerometer also enables measurement in any of the three axes where, in specialized cases, a single point accelerometer would be unable to measure data due to physical mounting restrictions or a dificult to access mounting surface.

For those who typically collect triaxial data, the sensor dramatically reduces data collection time For users who up until now have collected only one data point per sensor location, triax offers the advantage of additional information for improved diagnostics The triax accelerometer facilitates the eficient collection of accurate and repeatable machine date for enhanced decision making
