B&K Type 4573 Accelerometer DC Response, 30G, 67 MV/G

B&K Type 4573 Accelerometer DC Response, 30G, 67 MV/G

The DC Response Accelerometers are designed to measure low-frequency vibration down to DC. The gas- damped sensing element offers a wide dynamic range and very stable frequency response even after subjection to high shock levels.


  • Low-frequency, motion and tilt measurements
  • Flight testing
  • Road load testing
  • Transportation
  • Modal analysis

The accelerometer has built- in conditioning, where the sensing element and electronics are shielded, sealed and insulated from the housing.

D-versions are available offering high thermal stability from –55 to +121°C.
