With the addition of the output ground isolator to the Spider-80M or Spider-81, there are no additional steps required for the customer to ensure safe and accurate operation when a Spider system is being used to control independent amplifiers and shakers. Previously, users were required to link the amplifier grounds together with a specific type of cable and then connect them to the Earth’s ground, but users did not always follow these instructions.
Read MoreEDM Modal software provides the Playback Analysis feature which allows users to import recorded time signals and process measurement data to obtain the related spectrum signals. This feature allows users to carry out all the field measurements in one attempt before post-processing and analyzing the measured data in detail on a lab PC.
Read MoreThe new Vibration Visualization video produced by Aakash Umesh Mange (Crystal Instruments Applications Engineer) features the creation of 3D models for modal analysis.
Read MoreCentrotecnica recently used Crystal Instruments’ Spider vibration control system to conduct transport simulation testing for the Janssen (Johnson & Johnson) COVID-19 vaccine. Crystal Instruments is thankful for the opportunity to contribute to the global vaccine effort with our vibration control technology.
Read MoreRead MoreNASA will use the Crystal Instruments Ground Recording System, or CI-GRS for short, to gather data related to sonic booms, and in the future, the X-59’s quiet sonic thumps. A feature of the CI-GRS will be the ability for NASA to install custom software and algorithms tailored to various specialized operations for real-time analysis of sonic thumps. - Read article on NASA website

Read MoreThe orbit plot is not only used to understand the magnitude of the vibration during a vibration test but also to observe the phase relationship between the different channels used to acquire the response of the unit under test. This is understood more clearly using a test case.
Read MoreCrystal Instruments is pleased to announce the release of EDM 9.1, the most reliable and powerful version available from Crystal Instruments.
Read MoreThe Spider-80Ti is a front-end from the Spider-80Xi hardware platform that enables temperature measurement. Spider-80Ti supports temperature measurements from thermocouples and RTD (resistance temperature detector) sensors.
Read MoreThe Minimum Energy option of MIMO Random is implemented to handle the nonlinearity of a multi-shaker table and provide fast convergent control.
Read MoreA Swept Sine test is a type of vibration test where the controller excites one specific frequency via sinusoidal voltage drive. As opposed to a Random test, where a broadband of frequencies is excited together like white noise, the Swept Sine test produces a response with energy in the primary frequency and its harmonics (i.e., frequencies that are multiples of the primary frequency).
Read MoreThe Vibration Diagnostic System (VDS) software provides several important tools for machine predictive maintenance data collection, analysis and management. When synchronized with a CoCo handheld analyzer, the system integrates factory and route structuring, machine information, vibration data and analysis all in one place. The diagnostic algorithms are based on the concept of a machine model, and VDS provides a powerful tool for building machine models. This tool is called the Machine Builder.
Read MoreOperational Modal Analysis (OMA) is commonly used to monitor and evaluate the health of building structures to investigate for any damage [1]. Studying the modal parameters of the structure can assist in observing changes in the dynamic properties which can further help in predicting error in certain elements which might need some repair or modification.
