Speed reducers and other gearboxes are common industrial components. Monitoring their case vibration with accelerometers is an effective means of detecting problems within. To effectively diagnose these important mechanical elements, you need to understand the geometric details of their construction. Most importantly, you need to know the arrangement of shafts and the number of teeth on every gear within your transmission.

The CoCo-80 was an ideal choice as a portable vibration data collector for monitoring the health of the rotating machinery, specifically, HVAC equipment. The CoCo-80 weighs in at only 3.5 lbs, features an intuitive interface, and is rugged enough to operate in extreme conditions.
Read MoreCrystal Instruments welcomes Trung-Duong Nguyen as our newest Application Engineer. Trung-Duong has both a Bachelor’s and a Master’s degree in Aerospace Engineering, focused on space system transportation, CFD. Trung-Duong is experienced in FEA analysis, vibration, and system engineering. His master project was about using the classical approach of dynamics to measure strain and stress on a wing both experimentally and theoretically. Trung-Duong’s most recent achievements are the completion of full FEA Analysis on an aircraft’s amplifier and designing an altitude chamber to simulate and test avionic modules at 20,000 ft. Trung-Duong is also a martial art instructor, and in his spare time, he explores and learn techniques of digital concept art. He has an active lifestyle and believes that every day must be well spent with progression.

The Spider-81 Vibration Test Control System has the ability to continuously record any or all the the input channels, as well as the generated drive output signal. This is important when a record is needed of the entire vibration test. Recording is activated by a button in the Control Panel.
Read MoreCrystal Instruments is proud to provide quality test equipment to higher education institutes. Recently, Crystal Instruments delivered a data acquisition and vibration control system to Purdue University's laboratories for the Department of Mechanical Engineering. Included in the delivery was a full set of hardware equipped with software to enable complete shaker test control functions, iPad control in Dynamic Signal Analysis mode, and a premium version of EDM Post Analyzer software.

The major difference between CI and other Ethernet based controller products is that CI uses IEEE 1588 PTP to synchronize the sampling clock on different hardware units. The other products on the market usually require an additional trigger bus besides the Ethernet cable. The beauty of IEEE 1588 PTP is that all time synchronization is conducted on the same Ethernet cable that is used for network communication.
