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.

On October 27-29, 2014 James Zhuge, President & CEO of Crystal Instruments attended the 2014 Aerospace Testing and Industrial Control Show in Moscow, Russia. The Spider-80X vibration controller and the CoCo-80 dynamic signal analyzer were shown together with shaker systems from Sentek Dynamics at the DiPaul booth. The products were well received. A sales engineer from DiPaul gave an interesting product demo by playing music from his iPhone through a Sentek shaker. Attendees heard hip hop music when walking by the booth and found out that this high quality sound system, i.e., the ED shaker with low harmonic distortion, may cost hundreds of thousands of dollars! The Black Box mode capability of the Spider-80X system proved to be very convenient for setting up the demonstration. Attendees were surprised and intrigued to see that Crystal Instruments' vibration controller can operate on the shaker while the controller is not even connected to a PC.
Shock & Vibration Exchange 2014
As part of the international shock and vibration community, Crystal Instruments was proud to be one of the sponsors at the Shock and Vibration Exchange Conference this year in Reston, VA on October 26-29, 2014. Remy Chan, an application engineer from Crystal Instruments, represented CI this year at SAVE 2014.
Crystal Instruments is committed to the continuing innovation of shock and vibration technology. This year, we showed SAVE attendees the latest advances in our Spider-80X high channel vibration control system and the CoCo-80 handheld vibration analyzer. Demos also included the CI EDM software (engineering data management software), which is designed to operate efficiently and intuitively for the test and measurement professional.
Welcome Lin Fu - Technician
Crystal Instruments welcomes Lin Fu as one of our new Technicians. Lin Fu will be helping with the testing of vibration controllers and dynamic signal analysis systems, in addition to CI's EDM (Engineering Data Management) software for post processing.

Read moreCrystal Instruments Supports the Cleveland Vibrator Company
Crystal Instruments has recently provided the Cleveland Vibrator Company with a handheld CoCo-80 Dynamic Signal Analyzer to verify vibration levels of manufactured equipment. Cleveland Vibrator Company has been creating innovative material flow solutions since 1923, and are a manufacturer of industrial pneumatic and electric vibrators
The CoCo-80 Dynamic Signal Analyzer is an ideal solution for companies requiring real time data processing with the convenience of a portable, handheld system. The CoCo-80 Dynamic Signal Analyzer includes functions such as general signal analysis, FFT analysis, time recording, FRF data acquisition, alarm/abort checking, machine condition monitoring, and many more options.
Crystal Instruments Training at Danfoss
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 moreWelcome Trung-Duong Nguyen - Application Engineer
Crystal 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.

Crystal 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.
Read moreEthernet Becomes the Standard for Vibration Controllers
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.

A comprehensive white paper regarding the history of digital shaker controllers developed in the U.S. over the last four decades is available at NASA Tech Briefs website. This white paper is available free of charge.
Read moreDefine and Measure Dynamic Range
One of the breakthrough features of the CoCo-80, Spider-80X, and Spider-81 is their outstanding dynamic range performance of 160 dBFS. This kind of performance has never before been achieved with such small, portable, and low cost devices. The main advantage of this high dynamic range is that it eliminates the need to adjust the input gain/range settings on the front end, thus simplifying the setup and measurement process. Both full scale 10 volt signals and very small microvolt signals are measured at the same time with no adjustments. This capability makes setup and testing more simplified in comparison with an instrument capable of only a lower dynamic range.
