Adash A4900 Vibrio III NEW !
A4900 – Vibrio III is an innovative equipment for machine monitoring. It is powerful, but very simple in use. No PC is needed. Traffic light is used to indicate the severity level; and ISO 10816 rules are included.
What can A4900 Vibrio III do for you?
- check the vibration severity level
- determine the condition of your bearings
- find insufficiently lubricated bearings
- determine unbalance, misalignment and looseness
- check rotating parts (belt, fan…) by LED stroboscope
Instruments in this price have been able to measure only overall vibration values, but A4900 – Vibrio III measures:
- Overall RMS / Peak in velocity (10 – 1kHz), acceleration (500 – 16kHz) and displacement (1 to 1kHz)
- bearing condition (gENV)
- Velocity Spectrum (0-200 Hz)
- bearing time signal (accel 500-16kHz)
- automatic machine speed detection
- non-contact temperature measurement
You can also listen to the vibration signal,which is very useful in bearing fault detection especially for slow-running machine.
Stroboscope
The build-in stroboscope inside the A4900 Vibrio III represents the unique innovation in the handheld vibration equipment. High intensity LED is used.
Stroboscope is very handy for inspection of rotating or moving machinery (belt, fan, coupler…). For example, missing screw can be seen without stopping the machine – can be a big cost saving.
A4900 can automatic detect the rotating speed of the machine and freeze the movement by setting its flashing frequency the same as the rotating parts. Frequency can also be set manually.
Unbalance, looseness and mis-alignment
This screen gives an overview of the conditions of the followings by traffic light:
- unbalance
- looseness
- mis-alignment
Traffic light on the left (vertical) indicates the overall vibration condition
Traffic light on the right (vertical) indicates the bearing condition
Vibration levels
A4900 measures the RMS vibration level; and compare with the severity limits of ISO10816-3. Readings changes in Traffic Light color when exceedance.
Bearing temperature is measured by infra-red and indicated in traffic light. Overheat of bearing can be easily identified in RED bar as shown in the figure (left side). Temperature reading is shown in another screen.
RPM is automatically detected and displayed at the bottom of the screen.
Bearing fault detection
A4900 Vibrio III measures the g-ENV, which represents the condition of the bearing.
A4900 Vibrio III also display the vibration time signal. You can visualize the vibration impact due to bearing fault by looking at its time signal. It is useful in differentiating whether the increase in g-ENV is due to bearing fault or just lack of lubrication.
You can also listen to the vibration signal through the audio output, that is a proven technique for bearing fault detection especially for slow rotating machine.
Vibration Spectrum
A4900 Vibrio III measures the FFT spectrum (0-200 Hz); and list out the most dominates peaks. The information is useful for detection of unbalance and looseness.
Standard accessories
A4900 Vibrio III comes with a carry case which consists of
- A4900 Vibrio III
- accelerometer
- magnetic base for accelerometer
