Industrial accelerometer

Model 621B40 high-frequency industrial ICP accelerometer works with online or portable monitoring systems to provide reliable, effective vibration monitoring. It operates to 30 kHz, even with an attached magnet, and captures high-frequency gear mesh faults, often missed during routine route-based measurements.
