Test Cell Operation 

The test cell instrumentation consists of pressure taps and thermocouples in locations according to SAE J1826 specifications.  Sensors mounted in the horizontal, vertical, and axial directions provide a full vibration spectral and orbital analysis. To insure the accuracy of all collected data, sensors are calibrated with and are traceable to NIST standards. Multiple measurements from one location allows for the data to be scrutinized for instrumentation inconsistencies while under test. Finally, data integrity is maintained via storage a robust test database which is used to store all test data.

The control of the test cell is automated by using the NGML’s Opto22 control system. This automation permits cycle testing, specific ramp up and ramp-down testing, as well as any other programmed transient response.

A turbocharger under test will be operated at specified operating limits for speed, load, temperature, and pressure.
