High frequency accelerometers from PCB Piezotronics
24 June 2010
PCB Piezotronics has introduced a high frequency (30kHz) industrial accelerometer for gear mesh and bearing fault analysis. The 621B40 works with online or portable monitoring systems to provide reliable and effective vibration monitoring. It operates to 30kHz, even with a magnetic mount, and captures high frequency gear mesh faults that are often missed during routine measurements.
For higher frequency measurements, PCB Piezotronics can supply the 352A60 sensor with an upper frequency range of 60kHz (±3dB) that is designed to work with a stud mount adhesive base (supplied).
Principal performance specifications of the 621B40 sensor include sensitivity of 10mV/g, measurement range of ±500g and frequency range from 1.6Hz to 30kHz (±3dB). Shock resistant to 10,000g peak, the 621B40 operates over the temperature range -54 to +121°C.
