Catalog excerpts

The VC-2100 can serve as your vibration "watchdog" in a wide range of situations ɹ in which vibration-based judgments must be made, such as in go/nogo vibration testing of products, facilities diagnosis, and machine tool cutting tool damage. Combined with an acceleration pickup, it provides a full range of functions, ɹ from vibration detection through measurement and diagnosis, in a single package. >

It is possible to perform a go/nogo test of bearings based on vibration values. > The bearing is rotated and the diagnosis is made based on the resulting bearing vibration. By noting the vibration in a particular frequency band, it is easy to detect particular problems in bearings, such as damage, foreign matter, and unbalance). In addition to an acceleration pickup, it is possible to use a velocity pickup as the sensor. When using a velocity sensor, the VC-2100 is switched to external signal input. It is possible to detect abnormal operation of the main shaft of machine tools. > The runout...

Measurement: Digital and Bar-graph Display of Vibration Values > High-accuracy analysis is per-formed in accordance with analysis conditions, and a display is pre- sented of vibration values and vibration con-dition (bar-graph display). By displaying measurement screens for each band separately, it is pos- sible to collect the required data. Compact Size: 96 x 96 mm DIN Panel > The performance of more than two units have been housed in a space that is less than 1/5 that formerly re- quired. Provides EssentialSophisticated Features > Measurement and diagnosis of vibration is a complex...
