This software option offers a large set of results (up to 42) featured by the multiple available modes.- FRF acquisition : With its dedicated structural mode, the FFT plug-in features state-of-the-art FRF acquisition and analysis tools. During the acquisition you can preview coherences and averaged results to ensure measurement quality. - Synchronous Time Averaging (STA) reveals anomalies buried into noisy signals coming from rotating machinery. STA can also automatically synchronize the phase from spectral information.- Diagnostics : Envelope demodulation, Cepstrum, Kurtosis as well as the latest shaft view will let you easily find the source of a problem. The FFTDiag add-on offers a consistent tool set for on-site diagnostics of industrial machines.

Order AnalysisOrder analysis and tracking techniques are essential in measurements with varying rotating speeds. Getting correct results from run-up/down requires specific signal processing techniques. The NVGate® waterfall engine gathers the results of any plug-in, such as FFT or Synchronized Order Analysis (SOA), in a large, 3D dataset. The section manager features order cuts in the 3D space. It offers flexible cursors and investigation tools like the max order search. The Synchronized Order Analysis (SOA) plug-in harnesses the DSP powered OROS 3-Series analyzers to provide true order analysis. Signals are resampled with a dedicated tachometer input to be converted to the order domain. Then the plug-in extracts complex orders (phase and amplitude) from fast run-ups and or coast-downs.

Overall acoustic level meterWith an OROS 3-Series you get a multi-channel analyzer, so, why not turn your unit into a true multi-channel sound level meter. The OVA plug-in complies with the latest sound level meters standards such as IEC 60-672. It runs 3 RMS and a peak detector on each input. The detectors feature time filtering and weighting. Overall levels can be tracked during days in the profiles memory.

Time Domain Analysis (TDA)The Time Domain Analysis plug-in provides visualization and statistical analysis of signals in the time domain, featuring oscilloscope-like displays. This plug-in is useful for long duration signal monitoring and trend analysis on its statistical content.

Rotation measurementCrankshaft, transmission axes, belts, gear boxes and machinery shaft speed must be measured carefully in order to resolve the right order or torsional analysis on it. The OROS 3-Series analyzers are experts for such measurements featuring the best tachometer acquisition set. First, the quality of shaft speed determination is ensured with the 2 oversampled tach inputs (< 152 ns resolution) included in each analyzer. Then RPM speed can be treated depending on the situation.

The fractional tachometer computes the speed and phase of the output shaft of a gear’s line based on the input one.

The simulated one provides a user defined speed when it is impossible to get one from the machinery. Allowing order analysis in this case.The combined one computes, in real-time, 2 different tachs with your own formula, providing the speed of a CVT belt from the pulley speed.

For torsional vibration and acyclic rotating analyses, OROS 3-Series analyzers integrate frequency to voltage converters for each tachometer input. With its integrator filter and a smoother, it delivers direct angular information to any plug-in.

As well as all others function of OROS analyzers these advanced tachometer measurement tools operates in both real-time and post-processing.

Analysis ModesFFT, Order, Acoustics, DiagnosticsSoftware :

Software options come as modules in the NVGate® Analyzer setting browser (ASB). These modules, called Plug-ins integrate all the specific analysis functions with their settings. Functions and settings are organized in a logical way and spread on a maximum of 3 levels. The access to the plug-in setup is the always the same structure for each plug-in. General purpose plug-ins such as recorder, player, monitor and waterfall are standard.

1/n OctaveAcoustic signature and investigation require the appropriate analysis methods. The 1/n Octave plug-in computes levels from constant percentage band filtering, complying with IEC 1260 standard. Every parameter can be adjusted making a highly flexible acoustic analyzer. All channels can be analyzed real-time by the DSPs up to 20 kHz.

HardwareExpanding the capabilities and portability of the OROS 3-Series analyzers is easy with the standard or optional hardware.

Waterfall : a synchronized data buffer that offers comprehensive results explorationAcquire, analyze, all of these deliver quasi-instantaneous or averaging smoothed results. Getting the evolution of a phenomenon with these techniques requires long and repetitive procedures. The waterfall plug-in of NVGate® adds a new dimension to your results view point.

This specific plug-in is able to collect and to synchronize all data coming from the plug-in analyzers in a stack. Results are arranged regarding the different references (RPM, Time, and levels) and represented in 3D or profiles views. Fluid and extremely fast 3D representation offers multiple points of view for your data handling.

Synchronizing multi-analysis results offers great advantages. Identifying the critical point is then much easier having its effect on different modes such as order, structural resonance and acoustics. In the same way, working on this data space allows unpredictable and fine extractions of slices. The section manager of the waterfall plug-in feature orders, overall, constant frequencies and spectra extraction in one click.

The waterfall plug-in is also a deep profile manager; it can store up to 100,000 points per channel. Overall acoustic level, RPM or even temperature evolution is then shown clearly. Most of these profiles can be used as the reference axis for 2D and 3D displays. What is more clear than an acceleration spectrum evolution vs torque to interpret their interaction inside a transmission?

Recorder : Recording raw signals is the best way to keep a comprehensive trace of a measurement. OROS 3-Series offer as standard a recorder and a player plug-ins that provides flexible recording services. As the recording function is integrated, operations are greatly simplified. Whatever the analysis mode used, recording functionalities are easy to achieve. Backup of a real-time analysis like tests are now a straightforward possibility. Using the advanced triggering toolset, the recorder can reject unwanted upstream data.

The player is useful for time domain data manipulation and re-recording of file segments. File playback of a recorded signal allows listening of filtered and weighted noise. Associated with a shaker, this function is also a way to reproduce, in the lab, motions recorded in the field.

Carrying caseThe OROS 3-Series analyzers are mobile instruments. Each analyzer comes with a bag which carries the analyzer and all the accessories. And they comply with aircraft carry-on size restrictions.

Additional batteryOROS analyzers always integrate batteries (NiMh) as standard, providing autonomy and un-interruptible measurements. Additional batteries expand the autonomy of the instrument. These external batteries basically double the analyzer autonomy, and the hot swap capability allows for very long battery powered operations. The battery option is delivered with a battery charger, holder and fixing kit.

Mobi-DiskTM

OR36, OR38 and Mobi-PackTM are offered with a personal removable disk allowing useful sharing of your instrument within a team. OROS offers additional personal disks that widen the availability of your analyzer. Each user’s measured data can stay with him and let the team have the instrument for other uses.

You need more than an analyzer: the key information for you comes from advanced analysis methods. OROS 3-Series analyzers are provided with a comprehensive set of solutions that covers a wide range of applications. They are integrated in the analyzer software or come as third part software called NVSolutions®. Most of them operate directly with the analyzer providing immediate results such as sound intensity and order tracking. The other ones process the data file provided by the analyzer, such as modal extraction and reporting NVSolutions®.

Industrial acousticsCan you really afford to take your measurements with a middle class instrument? Making good measurements is always based on International Standards and their metrological requirements: IEC 651, IEC 804, IEC61672, IEC 1260, and more. No doubt: this can only be guaranteed by using a high-end instrument.

Because Sound Intensity is a field investigation technique, the testing solution must fulfill high requirements: precision, portability and flexibility. For the best efficiency, the interface is dedicated to sound power determination whether it is based on a point by point (ISO 9614-1) or on a scanning (ISO 9614-2) procedure.

Why keep measuring your entire set of microphone positions one after another during ISO374x Sound Power procedures? Think about all the advantages of measuring them all simultaneously:- No change in the measurement conditions.- No fuss while moving around a single channel instrument. Through a dedicated and simple interface the sound power solution gives you a type 1 precision result in the minimum amount of time.

Completing a product acoustic characterization by the calculation of some Sound Quality Metrics must be simple. OROS sound quality meter offers a straight forward calculation of the most common metrics such as Loudness, Roughness, Tone to Noise and more.

Rotating machineryAccurately measuring vibrations on TurboMachinery and reciprocating machines requires high performance instruments, especially for turbines, compressors, diesel engines and transmissions, where the speed is varying. Find the adapted analyses techniques in OROS Rotating Solutions fitting your measurements’ demands:Synchronous order tracking: Analyzing rotors and shafts where speed is rapidly varying must be performed with synchronous order tracking. No worries: the analysis is automatically optimized in real time to adapt to the changing speedThe Waterfall module gathers all the results (resonances, imbalance, modulation...) simultaneously in a large 3D dataset. This helps you easily localize the critical informationThe Constant Band order Tracking (CBT) helps engineers getting modulated and buried vibration orders on gearboxes with the appropriate band pass extraction.The Orbit Solution provides ORBIT and GAP diagrams, as well as Bode and polar plots for fluid film bearings diagnostics. They give crucial indications of the defects occurring on Turbomachines. Filtering the orbit as 1X, 2X or nX is also key. Using OROS analyzers, both DC and AC components of the proximity probe signals may be monitored thanks to the 40V inputs. The Balancing Solution provides a dedicated interface for balancing rigid rotors (on one or two planes). The imbalance position is determined using a time domain order tracking technique which gives is the most accurate phase determination.OROS 3-Series analyzers can process multiple tachometer/keyphazor. This unique feature easily detects rotor interaction as well as faulty shafts.

VibrationsTroubleshooting? Investigating? Accurately and efficiently measuring vibrations requires a simple and comprehensive solution based on precise FFT results. In the vibration solution, based on OROS 3-Series analyzers, all the required tools for vibrations analysis are there. In particular, placing automatic max and peak markers will let you spot and report the main frequencies of interest directly. Furthermore, the multi-analysis and a set of adapted tools open new perspectives to your measurements:Increase your comfort and data security with the ability to process FFTs in multiple bandwidths, resolution. Focus your attention on the bandwidth of interest while having an eye on the wide band spectrum. Isolate defects from multiple rolls, processing time averaging synchronized simultaneously by 4 different keyphasors.At the diagnostic stage, you will need to go deeper in the determination of the vibration signature. For that purpose, tools such as envelope analysis, zoom analysis, power and side band markers, kurtosis levels, cepstrum, correlation, and more are included. When studying non-stationary phenomena, looking at their evolution in time or as a function of measured static parameters such as oil pressure or temperature will let you analyze them with a new dimension.

Structural analysisGood structural analysis starts with good data! For that reason, all the tools for efficient and accurate acquisition have been integrated into our structural solutions: state of the art analyzer technology and applied user interface.Running through an impact hammer acquisition of modal data is made so much easier with the right tools:- Both forced and unweighted blocks display, double hits rejection, FRF and coherence preview, and Node path sequencer are tools known to be reliable by the mechanical engineers in charge of fitting models.- For operating on large structures, up to 6 shakers can receive signals from the analyzer generators. In order to fit the wide range of cases, a large series of excitation signals such as swept sine, chirp or random are simultaneously generated.

OROS Modal solution,OM2, is an easy and powerful tool for modal testing.OM2 offers a very intuitive and easy-to-use interface to progress rapidly through the different steps of a modal analysis. Accurate algorithms are available to generate Operating Deflection Shape, process Experimental Modal Analysis and also Operational Modal Analysis.The ergonomy of the software, improved by the modern way of implementation, allows to get rapidly a good evaluation.
