MAIN MENU

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Analyzer
Select the type of the measurement (from simple overall values through FFTs and time signals to more advanced measurements with Proximity probes such as Orbits), set up the measurement settings according to your requirements (frequency range, sampling, units etc.) and take all the predefined measurements simultaneously.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Route
Route module is used for day to day data collection of your factory machinery. Simply create your route tree with measurement points location in DDS software and take the measurements regularly. Transfer collected data to DDS software to watch the trends and analyze the data.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Run Up
Similar to Analyzer mode where you can setup any measurement which you like. RunUp allows you to control the saving of data for example as soon as possible, or by speed change, time change etc.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Recorder

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

BALANCER

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

FASIT - Expert system

------------------------------------------------------------------------------------------------------------------------------------------------------------------

Stethoscope
Do not use a screw driver to listen your bearing noise anymore. Place the sensor on the bearing house and listen the machine / bearing noise in headphones. VA4 Pro enables to listen signals from 4 channels. Just switch between individual channels. Adjust the volume according to your needs.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Lubri
Lubri is a maintenance tool used for monitoring and control of the lubrication process. Lubri measures the actual bearing lubrication status and informs the operator when the lubrication state is optimal.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Octave analysis
Octave analysis allows you to measure hearable sound. Connect your ICP microphone and measure sound level and Octave spectrum with selectable 1/1, 1/3, 1/12, 1/24 resolution.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

BUMP test
Easy way how to measure structure resonance frequencies. No need of any settings, just place the sensor on the structure and hit it with appropriate hammer.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

ADS
ADS - Animated deflection shapes software is based on the method of operating deflection shapes. This means we visualize the vibrations of certain machine by animation. During the animation the vibration movement is slowed down to very low frequency and the amplitude of the motion is increased so we can see the vibration. You can animate the machine motion directly on the VA4 Pro device!
