New accelerometer for fault analysis

摘要

PCB Piezotronics has launched a high frequency industrial accelerometer that operates to 30kHz for gear mesh and bearing fault analysis. The 621B40 works with online or portable monitoring systems to provide vibration monitoring, and it operates to 30kHz even with a magnetic mount. In addition, it captures high frequency gear mesh faults that are often missed during routine route-based measurements. The sensor is well suited for measurements on high speed compressors, gear boxes and turbo machinery, to provide early detection of impending problems.
