||A4900 - Vibrio 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
10816 rules are included.
What can A4900 Vibrio do for you?
- check the vibration severity level
- determine the conditon of your bearings
- find insufficiently lubricated
- 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
- Overall RMS / Peak
in velocity (10 -
1kHz), acceleration (500 - 16kHz) and displacement (1 to 1kHz)
Spectrum (0-200 Hz)
time signal (accel 500-16kHz)
machine speed detection
can also listen to the vibration signal, which is very useful in
bearing fault detection especially for slow-running machine.
||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.
looseness and mis-alignment
||This screen gives an overview of
the conditions of the followings by traffic light:
Traffic light on the
left (vertical) indicates the overall vibration condition
Traffic light on the right (vertical) indicates the bearing condition
||A4900 measures the RMS
vibration level; and compare with the severity limits of
changes in Traffic Light color when
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
RPM is automatically detected
and displayed at the bottom of the screen.
||A4900 Vibrio measures the g-ENV,
which represents the
condition of the bearing.
A4900 Vibrio also display the vibration time signal. You
can visualize the
vibration impact due to bearing fault by looking at
time signal. It is useful in differentiating
whether the increase in g-ENV is due to bearing fault or just lack
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.
||A4900 Vibrio measures the
FFT spectrum (0-200
Hz); and list out the most dominates peaks. The information
is useful for detection of unbalance and looseness.
A4900 Vibrio comes with a carry case which consists of
- A4900 Vibrio
- magnetic base for accelerometer
- coiled cable
- measuring tip for accelerometer
- 1.5V alkaline batteries
