The Crystal Instruments CoCo series are portable devices for vibration monitoring and predictive maintenance applications. The system consists of a CoCo analyzer and the Engineering Data Management (EDM) software. The CoCo is used to make field measurements and the EDM software in Vibration Data Collector (VDC) Mode is used to setup the CoCo hardware and define routes before field measurements, and to download data from the CoCo to analyze and archive afterwards.

Crystal instruments
The Vibration Diagnostic System (VDS) is a vibration data management system designed specifically for the machinery Predictive Maintenance (PdM) community. It harnesses the graphic display capabilities of Crystal Instruments EDM Software for the work of machinery vibration analysts. It allows the user to quickly get to the data for a machine of interest and displays that data in the familiar Tri-axial or Single Axis view. Users can quickly compare other data from the same machine, quickly navigate back into the historical data of the machine, and quickly compare the data to that of other machines in the database. The software supports the construction of Average (a.k.a. baseline) data for a class of machines and allows easy comparison to that data as well. A full suite of cursors designed specifically for PdM analysis is provided for inuitive user interaction with the data.In addition to great graphics, an extensible machine modeling system was developed specifically for vibration analysis. VDS allows users to model machines based on the elements of the machine that can contribute to the vibration energy of the whole. Model bearings, rotors such as motor bars, couplings such as flexible and fluid couplings, account for slip in fluid couplings, model gears and pulley systems, and model turbines by accounting for each stage. The system is wide open, users can create new elements to use within a system. Users that may not want to do all that are provided with a comprehensive library of machine components such as AC and Induction Motors, Couplings, Gears, Pulleys, Pumps, and other components. Single and double gear shafts allows users to model many kinds of gear boxes with an unlimited number of stages. This ability alone lets users model their machines to view and use to keep track of vibration pickup locations, record the forcing frequencies of each part of the system, and attach attributes such as manufacturer and other part information.

EDM Modal -
Crystal instruments
Engineering Data Management (EDM) is a PC-based software program designed for real-time data management and processing. This easy-to-use, Windows-native software manages the communication between the PC and all Crystal Instruments hardware platforms. EDM Modal is a complete Modal Testing and Modal Analysis suite for Experimental Modal Analysis (EMA). EDM Modal was developed based upon the sophisticated technologies of modern modal analysis theory and technique. With its intuitive controls and powerful features, EDM Modal is the ultimate tool for modal analysis applications. An intuitive interface allows users to manage highly complicated tests that can involve hundreds of measurement points and multiple excitations. This interface also allows for simple tests to be conducted quickly and with little effort. Regardless of how complicated the modal test is, EDM Modal provides the exact and precise tools required to achieve your goal.

EDM Multi-Shaker Control (MSC) is a software option included in the EDM testing package along with VCS. Multiple Shaker Control provides one centralized interface to interact with multiple controllers running separate tests at the same time. Multi-shaker controllers are not time synchronized unlike in MIMO VCS, in which all drives are time synchronized.

EDM Modal Sine Testing includes a dedicated test setup and operation process flow using a single or multiple modal shakers outputting a sine wave to acquire FRF signals. The Source Output type is either Swept sine or Stepped sine. The sweep mode can be linear or logarithmic. The FRF signals of each measurement DOFs with respect to defined reference DOF will be constructed. The output drive level can be defined to run the test under no control strategy, or the response of a control channel can be specified to run the test in a closed loop.

EDM Modal Operational Modal Testing (OMA Testing) includes a dedicated test setup and operation process flow using ambient vibration data. Using a large channel count data acquisition system (e.g., Spider- 80X or Spider-80Xi), the excitation method provides a much higher efficiency and accuracy for FRF measurements while minimizing local stresses on the test article.

Whole Body Vibration (WBV) testing is a type of vibration analysis geared towards estimating the effects on the operator. There are three categories of concern for the operator, health and comfort, perception, and motion sickness. The goal for any WBV test is to ensure that under normal operating conditions there is no significant or lasting effect of the vibration experienced by the operator.
