Why A4900 - Vibrio M?
You always ask before you make a decision to buy the new instruments what unit is the best for your
needs. Is it an instrument with a large amount of functions, including specialized software for data
processing (which you will not ever use), or is it an instrument which is easier to use and contains all
required functions? You should pay only for functions, which you will use in the field. The A4900 is just
that instrument. The instrument uses standard external accelerometer with the magnetic base. It
enables correct repeatable measurements. You should not equate our unit with "vibration pens".
The Adash model A4900 is a multi-function portable meter and data-collector that bridges the gap
between the basic and advanced FFT data-collector/analyser. It is a complete machine condition
expert system than gives results without the use of a computer or lap top. It is designed for the field
maintenance persons, technician, engineer and consultant who need to analyse a rotating machine
on-site without investing and carrying expensive instruments to site.
This single meter can measure overall vibration measurement, band graph, 800 lines spectrum, 2048
samples time signals, temperature, rotation speed, strobe scope. In addition it incorporates a strobe
scope, handy inspection torch and stethoscope.
The A4900 caters to ISO 10816-3 with expert rules covering machine health vibration levels, that
identify the prime machinery faults: Unbalance, Looseness and Misalignment. An anti-friction bearing
health level indication is also incorporated. Many informative screens are available.
Do your machines work under optimum conditions?
The A4900 will:
- Determines the condition of your bearings, including slow-running ones.
- Identify insufficiently lubricated bearings.
- Indicates unbalance, looseness, misalignment.
- Check machine speed by built-in stroboscope.
- Check machine temperature by non-contact temperature meter.
- Measures in either Metric or English units.
Operation of A4900 is easy to use. Colours green, orange and red display the status. Determination of
individual machine or bearings defect types is done directly during operation, without need of use a
computer or software. Despite the A4900 is very compact and rugged, it is designed and fits in the
palm of a small hand. Nevertheless the A4900 is big in performance.
The A4900 is supplied complete set with an accelerometer, coiled cable, magnetic base, transit case
and headphones. You can connect headphones to listen to machinery noise related to vibration and
process. When measuring transmissions or slow-running bearings, you will quickly appreciate the
benefits of the headphone accessory.
