Description

The vibration logger plots the vibration overall value (acceleration or velocity) in time. This can be used for several applications to track changes in the vibration overalls. The plot can be triggered manually or can be set to automatic take the readings.

Compatibility

This module is compatible with the following sensors:

  1. SensorWorks BluVib P-V-T (1 Axis)
  2. SensorWorks BluVib M-V-T-3 (3 Axis)
  3. Digiducer (1 Axis)

Main Menu

  1. The Start ► button will be disabled initially, until the sensor is connected. Select the sensor from the list of available wireless sensors, or connect the wired sensor to the tablet.

  2. The settings pop-up will allow the user to change the spectrum type to Acceleration in G's, Acceleration in dB and Velocity in ips or mm/s. The sampling rate and the number of samples can also be changed here, options will depend on the available sampling rate and number of samples of each sensor. Other options, such as windowing, filtering and cut-off value can be modified in the general Configuration view. See Configuration for more details. Setting the Continuous Monitoring to ON will automatically collect data, in the OFF position, the user will need to press the start button to take each reading.

    4. Note: This selection will affect all reading's raw data for all modules

  4. The FFT Settings will be set as defaults for all readings. Here the user can change the spectrum frequency units to Hz, CPM or Orders. A Cut-Off value can be added to remove low frequency values. Also windowing can be selected for the spectrum, the available options are: None, Hanning, Hamming, Blackman, Nutall and Flat-Top. The spectrum type and RMS/Pk values can be set as defaults here, but can also be changed in the settings pop-up of the spectrum.

Report

  1. The report view contains several options in the top bar menu: 1:Send by Email, 2:Save pdf locally, 3:Upload Report to the Cloud bucket, 4:Markup and 5:Report Configuration
