VIBROPORT 80 & VIBROTEST 80 • Machine Diagnosis • Field Balancing • Condition Monitoring

Machine evaluation, trouble-shooting and predictive maintenance The VIBROPORT 80 and VIBROTEST 80 are the newest generation of Brüel & Kjær Vibro’s portable measuring instruments. Since the early 1970s, Brüel & Kjær Vibro has been successfully developing solutions for condition-based maintenance and field balancing of rotating equipment in numerous industrial applications. This cumulative experience has resulted in the development of the VIBROPORT 80 and VIBROTEST 80 handhelds. Designed with powerful diagnostics and analysis, balancing and condition monitoring capability, these all-purpose...

Machine Diagnosis Field Balancing Condition Monitoring Powerful functionality for extensive application versatility With its extended monitoring, balancing and analysis capability, both the VIBROPORT 80 and VIBROTEST 80 can be used on a wide range of machines in the petrochemical, power and process industries. Their extensive measurement and sensor input capability make them the perfect choice for early detection and diagnosis of incipient faults in, for example, bearings, shafts, gears, couplings, or casings. This includes everything from balance-of-plant to critical machines, and even...

Machine Diagnosis Powerful vibration analysis One of the important principles of condition monitoring is early detection and diagnosis of a developing machine fault so maintenance can be planned ahead In this example, a compressor train is being analyzed by the VIBROPORT 80 or VIBROTEST 80. Real overall vibration measurements (not calculated overall values from spectra) such as the bandpass and a BCU measurement for bearing fault detection are measured during running conditions to get a glimpse of the general condition of the gearbox. If alarm limits are exceeded, a number of measurements...

Detailed diagnostics and analysis for all operating conditions Field diagnostics give a good understanding of the fault, but more detailed vibration analysis can be done on the host computer with the Report & Examiner software. Post-processing of the time signal, for example, enables you to more precisely analyze the detected fault, in order to determine its location and severity. This can include steady-state and transient analysis for FFT spectra and waterfall diagrams as shown below. Highlights of the FFT-ANALYZER MODULE (Spectral analysis) Highlights of the TRACKING MODULE (Order...

Field Balancing Field balancing made easy Field balancing is much more cost-saving than using a balancing machine, and in many ways more effective. In this example the VIBROPORT 80 or VIBROTEST 80 is performing a two-plane static and dynamic balancing on a motor, using the two-plane polar plot. The entire balancing process goes faster using the "Fire Key". After the field balancing you can upload all the data into the Report & Examiner software and issue a balancing report in Microsoft® Word. The VIBROPORT 80 plot display is ideal for field balancing. BALANCING MODULE • One or two-plane...

Machine Diagnosis Effective tools Transfer function determines the structural resonances by impact excitation on machines that are not rotating or on immovable objects such as foundations or casings. The transfer function (i.e. FRF, the frequency response, the ratio of the input impulse load and the measured impulse response vibration) is determined with an impact hammer having a built-in load sensor. In this example the VIBROPORT 80 or VIBROTEST 80 is being used to find a spurious resonance that has been causing the bearings on this motor to fail prematurely. The transfer function can be...

Efficient machine management One of the important principles of condition monitoring is data acquisition and monitoring to alarm limits. With the uploaded route, you are prompted to go from machine to machine, and measurement point to measurement point to collect data in a systematic, efficient way. If there is an alarm situation, you are notified and you can easily extend the route with additional measurements if needed. In this example, the VIBROPORT 80 or VIBROTEST 80 is routinely monitoring a COLLECTOR MODULE measurement routes with up to measurement point The VIBROTEST 80 is ideal for...

Setting up routes and analyzing data The Report & Route Manager host software enables you to quickly and efficiently set up a data collection route so it can be downloaded to the VIBROPORT 80 or VIBROTEST 80 instruments. The same software uploads data from the handheld via a USB connection to store it in the database and to do analysis on it. Up to 12 measurements per measurement point Data collection routes are fast to set up On-the-fly changes made in the field can be downloaded to the host computer ATEX version optional Powerful database storage and access Report & Route Manager software...

Machine Diagnosis Use one of the standard templates (e.g. ISO 10816) or a user-defined one to compare actual measurements to established limits for a given machine. In this example a VIBROPORT 80 or VIBROTEST 80 is being used to quality test motors from the factory assembly line. This non-route based data collector function easily guides you through the entire measurement process by showing a "mini route" (picture with measurement locations and directions) on the instru- ment and gives the results as a colour-coded pass/fail indication. It can also be used for testing serviced machines and...

Perfect choice of hardware and software components with full flexibility The VIBROPORT 80 and VIBROTEST 80 portable handhelds combine application versatility with a modular product concept that is easy to use by specialists and beginners alike. The VIBROTEST 80 is a more compact, lighter version of the VIBROPORT 80 with a smaller screen but the same functionality. The host monitoring software packages, which can be installed all current Windows® PCs, download and upload data to the instrument via a USB port. Reports are made in Microsoft® Word. There are two types of software: • Report &...
