The Engine Commissioning App was developed using the Caterpillar Standard for Engine Commissioning. The App collects data from one or multiple wireless sensors mounted in the machine under different load or operational conditions. For this test the user will define which sensor goes in each location and will start collecting data while the machine is in operational conditions. A full pdf report will be generated under CAT specifications for Engine Commissioning.


This module is compatible with the following wireless sensors:

  1. SensorWorks BluVib P-V-T (1-Axis)
  2. SensorWorks BluVib M-V-T-3 (3-Axis)
  3. Sensoteq® Chi (3 Axis)

Main Menu

  2. From the list of functionalities select Engine Commissioning.
  3. Note: The user can change the order of the functionalities in the list by dragging it from the right button on each cell
