VP-80 and VT-80VIBROPORT 80 and VIBROTEST 80 are the newest generation of portable measuring instruments. They are designed with powerful diagnostics and analysis, balancing and condition monitoring capability, these all-purpose instruments are easy to use flexible enough for a broad range of applications with modules for specific requirements. The two instruments can perform all of the same functions.

·VIBROPORT 80: With its large screen is perfect for in house measurements, The large screen also allows two-plane polar plots to be easily viewed.

·VIBROTEST 80: A more compact, lightweight version of the VIBROPORT 80, this instrument is ideal for field analysis/balancing. It provides fast and easy route-based data collection, monitoring the condition of machines, and balancing.

The VIBROPORT 80 and VIBROTEST 80 come in several ready to use starter packages with optional additional modules available to add on at any time to meet your monitoring requirements.

ANALYZER PACKAGE: The analyzer package includes powerful vibration analysis for general machine condition. This package merges the two main modules for typical applications in the machinery diagnostics day to day business: Overalls Module and the FFT-Analyzer with the Report & EXaminer Software (ReX).

If you want to check if your machine is within the operational vibration limit as per DIN ISO 10816, 7919 or the manufacturer’s limit values, the Overalls Module is your choice! Real overall vibration measurements (not calculated overall values from spectra) such as:

  • Simultaneous Visualization of up to three Vibration Values (a,v,s)
  • Measurement of Overalls vs. Time f(t) and Speed f(n)
  • Rolling-element bearing condition values
  • Speed of rotation
  • Flexible frequency range
  • Crest factor
  • Max. X/Y

To diagnose the location and severity of common faults in rotating machinery (e.g. generators, turbines, fans, aircraft engines, pumps, compressors, motors), the  FFT-Analyzer is the appropriate application module.

The following faults are typically diagnosed by an FFT spectrum:

  • Unbalance
  • Bearing faults
  • Bent shaft
  • Misalignment

BALANCER PACKAGE: The balancing package makes field balancing easy. Unbalance occurs in nearly all types of rotating machinery. With one or two plane field balancing the following machines can be balanced by means of the Balancer Module and Overalls Module with the Report & EXaminer Software (Rex).

  • High-precision machines
  • Small and large electrical motors
  • Automotive and railway engines
  • Reciprocating compressors
  • Fans, gears, pumps, hydraulic machines

DATA COLLECTOR PACKAGE: The Data Collector package allows for efficient machine management via route-based inspection. One of the important principles of condition monitoring is data acquisition and monitoring to alarm limits. With the Data Collector Module and Overalls Module with Report and Route Management software (ReO) you can upload a route and will be prompted to go from one machine to another in a systematic and efficient way to collect data. If there is an alarm situation, you are notified and can easily extend the route with additional measurements if needed. Key features of the Data Collector function are:

  • Unlimited number of routes (up to 5000 measurements / route)
  • Up to 12 measurements per point
  • Up to 2 channels plus reference sensor supported
  • Data review at site possible
  • Data import from XMS software possible

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. Some additional features that are available to add on to any package are shown below.

Coincidence between Rotational Speed and Resonances (Critical Speed)

For optimal operation of a machine, it is important to avoid (or minimize the duration) of the coincidence between the rotational speed and the structural resonance frequencies. This will minimize high vibrational loads during the run up, coast down or steady-state operation of the machine.

The Tracking Module allows you to determine the critical frequencies based on rotational excitation. Typical applications include:

  • Variable speed machinery
  • Centrifugal turbines and compressors
  • Engine tests
  • Machines operating during a run up or coast down

Identification of Structural Resonances of Immovable Objects

In combination with an Impact Hammer, the Transfer Function Module is used mainly to determine the structural resonances by impact excitation on machines that are not rotating or on immovable objects such as foundations or casings. Some key features are:

  • Measurement of the Frequence Response Function Output/Input
  • Direct Connection of Impact Hammer (CCS, ICP®)
  • Predefined Measurement Tasks, e.g. Stiffness, Compliance
  • Measurement of natural frequencies of a rotor

Data Recording & Post-Processing

Do you need to record a raw dynamic signal over a long time and save it in a standard file format for post-processing? No problem with the  Time Signal Module. Information can be recorded from:

  • Impulse events
  • Transient events
  • Random events
  • Machine cycles with start and stop phases

The data will be saved in a *.wav format, which can be processed by the Report & EXaminer Software and other types of analysis software.

Machine Quality and Final Acceptance Check

If you need to make quality checks in mass production and compare the machine state to pre-defined values or standards, the Acceptance Test Module is the module you are looking for. It is typically used for:

  • Vibration quality checks
  • Aircraft engine health checks
  • Testing after service
