  • Page 19: Getting Started With Measurements

    Vibration Measurement Instruments Getting started with Measurements The general procedure for measurements using VIBER X4™ can be divided into 4 steps: 1. Parameter check: When pressing OK, the instrument will check if the transducers meet the required conditions and start the data acquisition for the measurement. In the meantime, the instrument will display a diagram related to the stability of the input signal and, for some measurements, auto ranging will ask you to confirm the stability of the signal.
  • Page 20 Vibration Measurement Instruments General Measurement Settings In this section, the general application settings that are most commonly used by different applications are described. The settings can vary from application to application but their function is the same. Measurement type Millivolt, Acceleration, Velocity or Displacement. Depending on the choice, the instrument will integrate and display the units of measurement differently.
  • Page 21 Vibration Measurement Instruments Window (Hanning, Hamming, Blackman, Kaiser-Bessel, Rectangular) Windowing is used to shape the time portion of your measurement data in order to minimize edge effects that can result in spectral leakage in the FFT spectrum. The spectral resolution of your frequency result will increase if Window is used correctly.
  • Page 22 Vibration Measurement Instruments Hanning This is useful for measurements where better frequency resolution than some of the other windows is desired but where moderate side lobes do not present a problem (reso- lution is more important than amplitude accuracy). Hamming This window is optimized to minimize the maximum (nearest) side lobe, giving it a height of about one fifth that of the Hanning window.
  • Page 23 Vibration Measurement Instruments Averaging (Linear, Exponential, Smart, Peak Hold) Averaging means that the different parts are averaged together and can then be used for reducing random errors, such as background vibration due to a source other than the machine being measured. Linear means that each part spectra/value has the same weight in the final spectra/value.
  • Page 24 Vibration Measurement Instruments Frequency unit (Hz or CPM) With this setting you select which frequency unit is displayed, either Hertz (Hz) or Counts per Minute (CPM). Save Waveform with spectra If enabled, the analysis file will also contain waveform data. Speed Measurement Measures speed along with the measurement.

  • Page 25: Recommended Vibration Levels

    Vibration Measurement Instruments Recommended Vibration Levels This chapter describes the ISO standard 10816-3 and the recommended vibration levels. It also describes resonance and where to place the transducers for best result. The lists and tables in this chapter can be used as a first consideration when you approach a machine that is newly commissioned, or after some time in operation.

  • Page 26: Iso Standard 10816-3

    Vibration Measurement Instruments ISO standard 10816-3 The ISO standard 10816-3 classifies machines differently according to whether the machines are considered to be flexibly or rigidly mounted. This reflects the location of the machines stiff body resonances related to the basic running speed of the machine. For instance, a machine supported by rubber or spring has resonances at low running speeds.

  • Page 27: Measure (Off Route)

    Vibration Measurement Instruments Measure (Off Route) This section describes the applications in the Measurements menu. In this menu the programs are used to make an analysis on site or when you need to make additional measurements during Route. The following measurement applications are included in the instrument when delivered. See the specified application section for a detailed description.
  • Page 28 Vibration Measurement Instruments Phase In the Phase application you can measure the Amplitude and Phase of the vibration using 1 or 2 vibration sensors and a speed sensor. This tool will help you to confirm a specific machine fault or prevent false con- clusions.

  • Page 34: Bearing Condition

    Vibration Measurement Instruments Bearing Condition The bearing condition value is a sum average value, the RMS value, of all high frequency vibrations in the set frequency interval. This value is an acceleration average with the unit “ g ”. Interpretation of the Bearing Condition Value The bearing condition value is an indirect method of measuring the status of anti-friction bearings.

  • Page 39: Phase

    Vibration Measurement Instruments Phase In the Phase menu you can measure Amplitude & Phase using a vibration sensor and a speed sensor. The Phase application can help you diagnose machine faults such as, for example, resonance, misalignment, looseness and soft foot. The Phase application can also help you separate faults that at first look like unbalance but in reality are caused by something else (for example misalignment).

  • Page 40: Speed

    Vibration Measurement Instruments Speed The speed (machine revolution) can be measured with an Ex- ternal Tachometer. In the speed menu, all system resources are used only for speed measurement to get the best performance, this means that the accuracy and limits of the speed are ex- tremely high.

  • Page 41: Temperature

    Vibration Measurement Instruments Temperature In the Temperature menu you can, for example, measure the bearing housing tem- perature (or any other surface temperature) with the built-in infrared temperature sensor. Emissivity Set the coefficient for surface reflection factor (Emissivity factor) using a check via a contact probe (the table with emissivity factors is also included in the instru- ment’s context sensitive help menu).

  • Page 42: Audio

    Vibration Measurement Instruments Audio Listening to bearing noise is an established, proven method. Sound analyses of low speed bearings and gears can sometimes be much faster and even more reliable than BC value. This is also a good technique for estimating lubrication volume. NOTE The audio connector must be a 3.5mm stereo plug.

  • Page 43: Balancing

    Vibration Measurement Instruments Aadvanced measurements This section contains features that are not included in the standard version of Viber X4™ and ones that require licenses. Contact one of VMI’s authorized dealers close to your location to purchase licenses. Balancing Balancing is a procedure by which the mass distribution of a rotor is adjusted to ensure that the vibration and/or forces on the bearings at a frequency correspond- ing to service speed are within specified limits.
  • Page 44 Vibration Measurement Instruments Speed tolerance The tolerance of the current balancing speed is compared with the saved balancing speed to consider wheth- er the measurement is suitable for the balancing procedure. When the measured speed is outside of this tol- erance, the speed value will be shown in yellow.

  • Page 48 Response matrix VIBER X4™ calculates and stores the unbalance sensitivity called Response Matrix while you are balancing. Next time you want to balance the same ma- chine, you can use the Response Matrix and the instrument calculates the balanc- ing weights directly after the first trial run, or if all the transducers are already mounted, even while the machine is still in production.

  • Page 49: Waveform

    Vibration Measurement Instruments Waveform The waveform is the shape of a time domain signal as seen on an oscilloscope screen. It is a visual represen- tation or graph of the instantaneous value of the signal plotted against time. Inspection of the waveform can sometimes reveal information about the signal that the spectrum of the signal does not show.
  • Page 50 Vibration Measurement Instruments Waveform measurement When entering the waveform measurement, after the settings menu, a time domain signal window is shown in the middle of the display with some values shown above. On the top left of the screen, the amplitude value of the blue cursor is shown, in the middle, the amplitude value of the green cursor is shown and on the right, the frequency calculat- ed between these two cursors can be seen.
