Adash 4900 – Vibrio III
19
Special functions are included in the instrument for the determination of that three states. The overall
vibration values are colored with appropriate color.
The vibration limits
Adash
for each state are determined from the graphs, which are printed in the
Adash Limit Values of Machine and Bearing Vibrations
chapter.
Fasit Expert System
Press the left arrow on the screen No.1 and the FASIT screen appears. For correct evaluation the
speed must be defined. The instrument can do it automatically or by user manual entry.
In the left bottom corner you see the Machine icon. The vertical bar displays the general (overall)
machine condition. This condition can be evocated by many reasons. The unit evaluates the severity
of 3 sources, which are the most occurred in the practise:
- the Unbalance ( the circle with heavy spot icon),
- the Looseness ( the shoe icon)
- the Misalignment ( the clutch icon).
Correspondent faults horizontal bars are in middle.
On the right bottom corner you find the rolling bearing icon. The vertical bar displays the bearing
condition.
The Stroboscope
The build-in stroboscope inside the A4900 Vibrio III represents the unique innovation in the handheld
vibration analyzer field. We use the high lighting LED technology, which low power consumption
enables to use the stroboscope in our instrument.
Stroboscope
or stroboscopic lamp, commonly called a strobe, is the device which produces regular
flashes of light. When we have to study or to visually inspect the machinery, which have cyclically
moving parts, then the stroboscope enables to froze the moving ( usually rotation). Imagine the
simplest form, a rotating disc with one-spaced hole. When the flashes of light are synchronized with
the rotational speed of the disc, then just one flash is made during one rotation. It means, the disc is
lightened up when the hole is always in the same position. It is the principle of illusion of frozen
movement. See the Menu chapter for details.
