Vibration Analyser for Professionals

The A4400 VA4 Pro II is a unique 24-bit, 120 dB instrument for machinery vibration diagnostics. Beside its ability to simultaneously in 4 AC Channels, 4 DC Channels and 1 Trigger; the A4400 VA4 Pro II has complete built-in modules for analysing, data collecting and the recording of vibration signals, in-situ balancing, run up and cost down, control and checking of lubrication and listening to vibration signals by the stethoscope feature.

The instrument is equipped with an expert system that automatically detects machinery defects and the ACMT – low speed bearing analysis; both developed by Adash.

The A4400 VA4 Pro II has unmatched 3,276,800 lines resolution in real time with frequency range up to 90 kHz  is designed for engineers and technicians dealing with machinery and structural as well and dynamic balancing of rotating machinery.

Data Acquisition Time

The VA4 Pro analyser with built-in high speed chips approach the job with much more advanced concept. For every individual Parameter created in the instrument memory; the internal virtual analyser will set the instrument to store the single input signal into DSP board and perform required data acquisition internally; it means that the total required time is not equal the sum of all individual times, but it is equal the time required for the single longest parameter – base on previous example – it will be only 8 seconds.

That means – with the triaxial sensors, the VA4 Pro can collect all the parameters in 3 axes for only 8 seconds against the 96 seconds required of a single channel analyser to measure in 3 axes!

This 12 times* in time saving means that there is no time lag and phase angle between the first and last measured parameter as they are using the same input signal, this also especially important to provide simultaneous results in 3 axes during trouble-shooting mode.

Note:

12 times in time saving when compared against conventional instrument using single sensor, 4 times in time saving when compared against conventional instrument using a triaxial sensor

The larger number of parameter utilised in the instrument, the higher is the percentage in time saving.
