Vibration Inspection of products  [Vibration from equipment]
vibration A-1-11 Inspection of a rice cooker before delivery (operation checking)
 

 

  • In this example, the VC-2200 vibration comparator detects vibration by mounting a sensor on a measurement object (attachable/removable by using magnetic base) for an operation check of pressure adjustment valve in a rice cooker. In a conventional inspection method, the operator has to listen carefully the abnormality from operated sound of pressure adjustment valve. The judgment by vibration value reduces the strain on ears of operator and the time for inspection process. The Pass/Fail judgment is made by the deference of vibration value. The control by measured value and checking of vibration sound by headphones can be performed at the same time.
     
  • The VC-2200 can be setup two frequency bands, and make Pass/Fail judgment based on the rms or the peak value on each band. The VC-2200 has effective functions such as comparator delay time setup function for reduction of unwanted signal at the time of measurement start and automatic operation function in order to control the judgment timing by input the gate signal from external equipments such as PLC*. You can use the VC-2200 at 100VAC with VC-0352 AC/DC converter as well as 24VDC (22 to 26VDC) as a power source.
     
  • By connecting a pair of commercially sold headphones to the VC-2200, it is possible to make an auditory check of the 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 separately.

* PLC: Programmable Logic Controller
