A4300 VA3 EX
EX approved vibration analyser for advanced machine diagnostics in ATEX areas
The A4300 VA3 EX is a handheld EX-approved vibration analyser designed for advanced vibration analysis and troubleshooting on rotating machinery in hazardous areas.
The instrument combines advanced analysis capabilities with robust design and intrinsic safety, making it possible to perform detailed vibration analysis in areas where conventional measurement equipment cannot be used.
The A4300 VA3 EX is typically used by vibration technicians and maintenance personnel working with Predictive maintenance, troubleshooting and machine diagnostics in ATEX environments.
A4300 VA3 EX - advanced vibration analysis in EX areas
In many industries such as oil & gas, chemical and process industries, rotating machinery is found in areas where EX-approved equipment is required.
Med A4300 VA3 EX you can perform advanced vibration analysis directly in these environments without compromising safety.
The instrument makes it possible to:
- Analyse vibrations in both the time and frequency domain
- Identify faults in bearings, gears and other components
- Perform advanced troubleshooting directly on the machine
- Document vibration state over time
The A4300 VA3 EX is designed for organisations that work systematically with Condition monitoring and predictive maintenance in ATEX areas.
What errors can A4300 VA3 EX identify?
Using vibration analysis, the A4300 VA3 EX can be used to identify a wide range of typical machine faults, including:
- Imbalance
- Misalignment
- Mechanical looseness
- Rental damage
- Gear failure
- Resonance issues
- Structural vibrations
- Electrical faults in motors
By analysing frequencies and signal patterns, faults can often be detected at an early stage before they develop into downtime.
Meter mode
Meter mode Used for quick vibration measurements directly on the machine.
In this mode, the instrument acts as a classic vibration meter where the operator can quickly check the machine's vibration level without performing a full analysis.
The instrument displays vibration levels in:
- Velocity
- Acceleration
- Displacement
Meter mode is particularly useful for:
- Quickly check the vibration state of machines
- Screening of machines in operation
- Control measurements after repair or maintenance
- Verification of vibration levels against standards
This mode allows you to quickly determine if a machine is running normally or if more detailed analysis is needed.
FASIT mode
FASIT mode (Fault Source Identification Tool) helps automatically assess possible causes of machine failure based on vibration measurements.
Once the measurement is complete, the instrument analyses the vibration data and compares the signal to typical patterns of known machine faults. The result is presented as an overview of the most likely fault types.
FASIT mode can help you identify, among other things:
- imbalance
- misalignment
- mechanical looseness
- bearing frame
- Gear-related vibrations
This feature gives the technician a quick overview of the machine's condition and can be a great help when Quick troubleshooting in the field.
FASIT is particularly useful in situations where:
- The vibration technician needs a quick assessment
- Screening of many machines is carried out
- measurements are performed by personnel with limited experience in vibration analysis
However, FASIT mode should always be seen as a diagnostic aid, which can then be supplemented with more detailed analysis in analyzer mode.
Analyzer mode
Analyzer mode is used for Detailed vibration analysis and troubleshooting directly in the field.
In this mode, the technician can perform advanced measurements and analyse vibration signals in both the time and frequency domain.
Analyzer mode gives access to features like:
- FFT analysis
- time waveform
- envelope / demodulation
- spectrum analysis
- different measurement settings
This mode is typically used when you want to identify the cause of a vibration problem more precisely.
Route mode
Route mode is used for systematic vibration measurements on machines in a maintenance programme.
Here you can create measurement routes in DDS software, which is then transferred to the device. The technician can then follow the route and take measurements at the defined measuring points.
The advantage of route mode is that measurements are performed consistent every time, which makes it possible to follow the development of the machine's vibrations over time.
Route mode is typically used for:
- predictive maintenance programmer
- Regular monitoring of machines
- Trend analysis of vibrations
- Documentation of machine condition
Balancer mode
Balancer mode makes it possible to perform Dynamic balancing of rotating machinery.
Using vibration measurements and phase information, the instrument can calculate how much weight needs to be added or moved to reduce imbalance in the rotor.
Balancing can often be done directly on the machine without dismantling the equipment.
Balancer mode is typically used on:
- fans
- pumps
- rotors
- turbine
- Other rotating components
Proper balancing can significantly reduce vibration and extend the life of both bearings and machine components.
Run-up / Coast-down mode
Run-up / Coast-down mode is used to analyse vibrations as the speed of the machine changes.
During a run-up measurement the instrument detects the vibration signal while the machine accelerates from low speed to normal operating speed. During a coast-down measurement the vibrations are detected while the machine is braking.
By analysing the vibrations during changes in speed, you can identify dynamic phenomena that are not necessarily visible during normal operation.
Run-up / Coast-down analyses are used to identify, among other things:
- Resonant frequencies in machines and structures
- critical speeds
- structural vibrations
- Imbalance in rotors
- Dynamic problems in axle systems
The result is typically presented as a waterfall plot or a velocity-dependent spectrum, where you can see how the vibrations develop at different engine speeds.
This type of analysis is particularly useful for Troubleshooting turbines, fans, pumps and other rotating machinery, where the vibrations change with speed.
DDS analysis software
Measurement data from A4300 VA3 EX can be transferred to PC and analysed in DDS (Digital Diagnostic System).
DDS makes it possible to work systematically with vibration analysis and condition monitoring.
With DDS you can, among other things:
- Store and organise measurements
- Build measurement routes
- Analyse spectra and time signals
- Compare measurements over time
- Generate reports
This makes it possible to implement a structured predictive maintenance programme, also in ATEX environments.
Typical applications
A4300 VA3 EX is used for vibration analysis on rotating equipment in areas with requirements for EX-approved measuring equipment, for example:
- pumps
- electric motors
- fans
- gear
- compressors
- Process equipment in the oil, gas and chemical industry
The instrument is typically used for Advanced troubleshooting, analysis and condition monitoring on machines in potentially explosive atmospheres.
