Adash America VA3 4300 Base Unit Two Channel Datacollector and Analyzer

Adash A4300-VA3 is portable very modern construction one or two channel data collector and analyzer. Main features are small dimensions and weight (970 g), large LCD display with high resolution and powerful processor which provides fast data analysis.

Adash A4300-VA3 is determined for bearing condition analysis, lubrication analysis and analyses of mechanical defects of machines - unbalance, misalignment, resonance, looseness. Enables to perform any of the FFT, order or time signal analyses. Instrument memory enables archiving of large amount of data. The most important feature is possibility of firmware upgrade via interface RS232. Instrument can work as data collector or analyzer and the switching between these modes is by one button push. There are implemented special methods for measurement of bearing condition, where is low speed bearing included. With software system DDS 2000 is A4300-VA3 instrument very powerful weapon in predictive maintenance.

For bearing and lubrication analyses several methods are implemented. There are Bearing, L-Bearing and envelope analyses, Crest a Kurtosis factors. Measurement with bearing method is the base way for bearing condition analysis. The physical base of the method is an occurrence of a considerable increasing of high frequency signal energy. All these factors are also very sensitive for lubrications breaks. Envelope analysis in connection with FFT analysis can determine, witch part of bearing is wrong (outer race, inner race, cage or ball). Crest factor is very sensitive parameter for early defect detection. This method is independent of bearing type and machine speed and it is also helpful parameter of lubrication check. The Kurtosis factor represented statistical approach. A4300-VA3 includes also all tools for mechanical defects detection. Mechanical defect with bearing defects represents the most of maintenance problems. Each defect can be checked by more than one method, this feature increases the reliability.

Adash A4300-VA3 is manufactured in several modifications. The standard are Analyzer Trend or Pro. It is possible to add next modifications: Data Collector, DualChannel, Balancing and it is possible to develop a special modification regarding customer needs.

• Analyzer Trend: Enables measurements of overall (wideband) values, envelope analysis, bearing condition values, process values and speed. Measurements are executed in multiplexed 2-channel mode (not synchronous). Data are saved into memory for next evaluation.
• Analyzer Pro: Enables measurements of overall (wideband) values, time signals, FFT spectrum, Order (tracking) analysis, envelope analysis, bearing condition values, process values and speed. Measurements are executed in multiplexed 2-channel mode (not synchronous). Data are saved into memory for next evaluation.
• DataCollector: Enables in addition to use all possible measurements (Analyzer Trend or Pro) in Datacollector (Route) mode. The route is defined in DDS 2000 software. Important feature is the possibility of manual input from instrument keyboard.
• DualChannel: Synchronous (simultaneous) measurement in 2 channels.
• Balancing: Balancing in one and two planes with trim measurements.
