PCB Piezotronics has launched a
high frequency accelerometer that
operates to 30kHz for gear mesh and
bearing fault analysis.

The 621B40 works with online or
portable monitoring systems to
provide reliable vibration monitoring.

It operates to 30kHz even with a
magnetic mount and captures high
frequency gear mesh faults.

Due to the sensor’s high frequency
range, it is suitable for measurements
on high-speed compressors, gear
boxes and turbomachinery.With a
magnetically mounted 621B40
supplying a response to more than
30kHz, a vibration analyst can obtain
precise measurements, revealing high
frequency phenomena. For higher
frequency measurements the 352A60
sensor has an upper frequency range
of 60kHz at ±3dB.
