The CF-4500 FFT comparator can make OK/NG judgment and quality
inspection accurately by analyzing the frequency signal of sound or vibration
from products or parts on production lines.
Measuring sound or vibration is popular as an effective method
for quality control of products having driven section such as a motor. To ensure
higher quality, needs for finding and capturing characteristic signals have been
increasing as well as sound or vibration level in recent years. As being
incorporated our accumulated FFT technology over the years, the CF-4500 enables
OK/NG judgment by extracting caused and characteristic frequency component.
The CF-4500 provides three newer functions in addition to
[Block comparator function] which can make OK/NG judgment by characteristic
frequency level in signals. [Shape comparator function] enables OK/NG judgment
by using signal form. [Tracking function] can also make OK/NG judgment even
though rotational speed is changing. You can check abnormal sound by your ears
with [Band-pass filter & monitor function]. The combinations of these
judgment functions greatly help in higher quality improvement and working
effectiveness at production site.
Features
Up to maximum of 20 blocks can be specified
as judgment area in characteristic frequency signal levels. The judgment
method can be setup for each block.
Three kinds of OK/NG judgment function allow
precise inspection of various products. In addition to [Block comparator
function], [Shape comparator function] (option) can make OK/NG judgment by
signal waveform. [Tracking function] (option) enables OK/NG judgment by
capturing changes of specified order level even though rotational speed is
changing.
Also, an operator can make judgment while
checking characteristic abnormal sound by him/her own ears thorough
headphones with [Band-pass filter & monitor function] (option).
Incorporation of a 6.5-inch color LCD touch
panel has enabled easy reading of measuring waveform or judgment result.
Moreover you can specify judgment area only by touching and dragging your
finger on a screen.
As USB interface is equipped with the
CF-4500, measurement data or judgment result can be managed in a PC by means
of copying those data in USB memory.
In view of measurement on production line,
the CF-4500 has battery backup function (option) which enables closing the
application normally in case of going down a main power or instantaneous
power failure.
