Digital filters are powerful tools utilized during the data conditioning phase to analyze signals. These filters empower users to augment signal processing capabilities by integrating them with other data conditioning modules, thus generating advanced post-analysis functionalities. Among the primary types of real-time digital filters are the Decimation filter, the FIR (Finite Impulse Response) filter, and the IIR (Infinite Impulse Response) filter.

Read MoreOur team is thrilled to announce the 11.1 version of Engineering Data Management (EDM) software. Packed with a range of new features and improvements, this update is designed to elevate the user experience.
Read MoreDSA is often referred to Dynamic Signal Analysis or Dynamic Signal Analyzer depending on the context. DSA uses various technologies for digital signal processing. Among them, the most fundamental and popular technology is based on the so-called Fast Fourier Transform (FFT). The FFT transforms the time domain signals into the frequency domain. To perform FFT-based measurements, it is important to understand the fundamental issues and computations involved.
Read MoreUsing purpose driven equipment like the CoCo-90X, an advanced battery powered dynamic signal analyzer that scales up to 16 input channels, IVC Technologies can collect more input channels than traditional walk around data collectors and can record time streams for several minutes or longer to observe and capture data from the entire raising and lowering of the bridge in one data set. With 16 channels, vibration data can be collected on the motors, gearboxes, and sheave bearings synchronously. This both reduces the overall collection time and increases the ability to properly access the synchronous data.
Read MoreThe latest release of version 2.2 CoCo Software includes notable updates such as support for 1 hz resolution, an IEPE powered tachometer, Waterfall & Colormap signal reviews, and the ability to sync VDS user profiles on a CoCo device.
Read MoreThe auto-wake feature is a new and powerful function provided in EDM 10.0 software. This feature allows users to set up a wake-up alarm for Spiders to power on, perform a test, and power off. Users can upload up to 8 predefined tests and run these in Black Box mode (without a connection to a computer or network to run). This convenient mode allows users to acquire data autonomously or with little user intervention.
Read MoreSome data acquisition applications will inevitability run into one of the most common problems of the information age: information overload. Today, modern DAQ systems, such as the highly versatile Crystal Instruments Spider product line, can store significant amounts of vibration data. Now, memory limitations are significant. However, sifting through large amounts of data in order to capture a small transient event is undesirable.
Read MoreCrystal Instruments is excited to announce the release of EDM 10.0, the latest software version for all Spider and CoCo products serving advanced and fundamental industries in addition to furthering academic advancements.
Read MoreFounded in 1996, Crystal Instruments designs and manufactures instrumentation products for machine vibration monitoring, dynamic measurement, and environmental testing. The products are developed in Silicon Valley and our modern lab in North Carolina. Crystal Instruments products are thoroughly tested on a variety of vibration shakers and environmental chambers in our lab during the design phase to meet the extreme requirements of military and aerospace applications.
Read MoreThere are two steps for converting an analog signal into a digital signal – quantization in time (sampling) and quantization of amplitude. Any signal that goes through the sampling process is subject to the effect of aliasing. The common use of the word ‘alias’ is used to describe a false name or identity, which is similar to how the term is used in signal processing.
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 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 MoreThe accurate measurement of micro-vibrations is the first step of successful vibration contamination control. According to generic vibration criteria for vibration sensitive equipment, the RMS velocity of vibration criterion is from 50 to 3.1 μm/s (2000 to 125 μin/s). To measure such small amplitudes, high sensitivity and low frequency sensors must be used. Crystal Instruments provides the Wilcoxon WR 731 and PCB 393B31 accelerometers with the CoCo-80X data analyzer for this application.
Read MoreOff Route measurements are linked to machines in the database using a system called Job Management. When taking Off Route data, the measurements are stored under jobs and each job is assigned to a machine. The job-machine relationship is maintained after syncing the CoCo with VDS, so Off Route measurements are automatically associated with the correct machines.
