The EDM Vibration Visualization feature is available in all modules of EDM software (VCS, DSA and Modal). This option provides fast and efficient structural model generation and full 3D visualization of the online vibration pattern on the structure under test
Read MoreCrystal Instruments is pleased to announce the release of EDM 8.0, the most advanced featured version of Engineering Data Management software. This new release of EDM supports exciting new hardware systems, convenient new software features, and helpful online resources.
Read MoreThe Spider-80Xi platform gives users the immense flexibility to combine the Spider-80Xi, Spider-80SGi or Spider-80Ti devices into one system with synchronized data acquisition. The Spider-80SG and Spider-80SGi can work as general-purpose data acquisition systems that not only supports strain measurement but also supports several sensor types requiring precision excitation voltage, including MEMS and strain gage based sensors. The Spider-80Ti on the other hand can acquire temperature data along with any other type of measurement quantity by using it with any combination of Spider-80Xs and Spider-80SGs.
Read MoreThe Ethernet connection interface is one of the most important features of the 4th generation Spider series vibration controller. It provides the flexibility of location, reduces noise and electrical interference, and uses one PC to monitor multiple controllers.
Read MoreThe future is here! Crystal Instruments’ newly released EDM Cloud service and enhancements to the online CI Store launch us into the current century and beyond; no end in sight to our innovative spirit.
Read MoreThe CoCo-80X’s latest software release includes a new signal analysis project for Sound Power applications. The Sound Power CSA features a graphic interface to show the test point status. There are multiple test room types and microphone arrangements. When the test is complete, a report is generated.

Read MoreCrystal Instruments is currently working on the latest and most advanced featured version of EDM 8.0. The following is a brief preview of what can be expected from the EDM 8.0 Version release:
Read MoreCrystal Instruments exhibited a highly advanced new set of tools called “EDM Modal”, at IMAC 2019 in Orlando, Florida. IMAC XXXVII maintained a broader focus and chose this year’s theme as “Predictive Modeling for Engineering Design and Decision Making.” The conference took on a note of focusing more on general-purpose data acquisition while still maintaining a strong academic focus on the principles of modal analysis.
Read MoreCrystal Instruments will be hosting an “Experimental Modal Measurement and Analysis Seminar” from February 26 - 27, 2019, at the Biltmore Hotel in Santa Clara, CA. All are invited to attend. Registration cost is $199, click here to register.
Read MoreStudying the modal properties of the structure under test is important to optimize the design of the test structure and to improve the NVH characteristics. Finite Element Analysis is widely used to obtain the mechanical properties of different objects. However, it is not only difficult to replicate the exact environmental constraints and boundary conditions but also challenging to obtain the damping ratios of the different modes. Experimental modal analysis not only helps in solving these issues but can also help in validating the results of the finite element model.
Read MoreRoving excitation or response? Uni-ax or Tri-ax? SIMO or MIMO?
A modal impact hammer test is broadly classified between two types: roving hammer and roving response. Each method has its own pros and cons.
Read MoreThis month, as part of a routine ISO 9001 audit process, we made a slight revision to Crystal Instruments’ “scope of business" statement. It now states:
The design, production, sales and servicing of hardware and software for machine vibration monitoring, dynamic measurement and environmental testing.
Read MoreMeasurements can be broadly classified into two categories: Static Measurements and Dynamic Measurements.
Dynamic measurements vary greatly over a short period of time (e.g., Vibration (Acceleration), Audio (Sound pressure), etc.). In these types of signals, we are mainly interested in the high frequency components so measurements down to DC are typically not necessary. For these measurements, we would use the AC input mode (or IEPE) which comes with a 0.375 Hz High Pass Filter. In most cases, the user sets another high pass filter to eliminate the low frequency components that are not needed. Crystal Instruments Spider-80X and Spider-80Xi systems are best suited for these types of applications.
Read MoreCrystal Instruments and Sentek Dynamics attended the 89th Shock and Vibration Symposium in Dallas, Texas. The symposium, which is organized by Shock and Vibration Exchange (SAVE), is regarded as the leading forum for the structural dynamics and vibration community to present and discuss new developments and on-going research. The technical paper presentations and tutorials offered at the symposium revolve around applications such as shock-ship testing, earthquake engineering, structural dynamics, and shock and vibration instrumentation techniques; attracting attendees from all over North America.
