The CF-4500 FFT comparator performs accurate pass/fail judgments and quality inspections by analyzing the frequency of sound and vibration from products and components on the manufacturing line.
Up to 20 blocks can be configured to make decisions based on the level of characteristic frequency signals, and the decision method can be set individually for each block.
In addition to the block comparator function, the system can handle precision inspections of various products thanks to its "shape comparator function" (optional), which determines pass/fail status from waveform shape, and its "tracking function" (optional), which captures and determines level changes of a specific order while varying the rotation speed.
The optional "bandpass filter and monitor function" allows field workers to check for distinctive abnormal sounds using headphones, enabling them to make judgments while listening with their own ears.
Featuring a 6.5-inch touchscreen color LCD, it makes measurement waveforms and judgment results easy to view, and the judgment area can be easily set by dragging while touching the screen.
Equipped with a USB interface, measurement data and judgment results can be copied to a USB memory stick and managed on a PC or other device.
Considering line measurements, a power backup function (optional) is provided to ensure the device can shut down properly even in the event of a momentary power outage or main power failure.
Measuring sound and vibration is a widely used and effective method for managing the quality of products with drive components such as motors. In recent years, there has been an increasing need to capture characteristic signals, not just the magnitude of sound and vibration, in order to ensure higher quality. The CF-4500 utilizes our long-cultivated FFT frequency analysis technology to extract problematic characteristic frequency components and perform pass/fail judgment. In addition to the "block comparator function" that determines pass/fail based on the level of characteristic frequency signals contained in the signal, it is equipped with a new "shape comparator function" that determines pass/fail based on the shape of the signal, a "tracking function" that determines pass/fail while changing the rotation speed, and a "bandpass filter & monitor function" that allows users to hear abnormal noises that indicate defects. By combining these judgment functions, it is possible to achieve higher quality improvements and improved work efficiency in the production field.
