• If a cutter blade is broken, all textile of the lot should be thrown away because the broken cutter blade may be remained in a textile. Detecting a breakage of cutter blade is indispensable to prevent such a large loss. Today, metal detector or the like monitors whether a broken edge is mixed in textile or not. In this example, the VC-3200 monitors constantly and detects abnormal vibration to find breakage of a cutter blade by a sensor mounted on a measurement object (magnet attachable/removal). This application gives an alert with signal tower when it detects the breakage and greatly helps to reduce maintenance cost.
   
• The VC-3200 can be set up three frequency bands and make Pass/Fail judgment based on rms, peak or power averaging calculated value (same for all bands) on each band. Also it has effective functions such as comparator delay time setup function and auto operation function. The comparator delay time setup function removes unwanted signal at the time of starting measurement and the automatic operation function can control the timing of judgment by inputting a control signal from external device such as PLC*. Although the VC-3200 can be operated by 24 VDC (22 to 26 VDC) as standard, you have an alternative to use it at 100 VAC by connecting the optional AC/DC convertor VC-0352.
   
• Connecting the VC-3200 to a PC via RS-232C interface enables storing measured data and so on.
   
• By connecting a pair of commercially sold headphones to the VC-3200, it is possible to make hearing check of vibrating sound. Moreover, it can be used instead of conventional stethoscopic probe. Output signals are provided for each band, enabling an observation for vibration phenomenon on each frequency band.
