Designed for in-the- field calibration of vibration measurement
chains, this portable unit offers a stable and reliable vibration
signal of 10 m/s2. Due to the frequency of 159.2 Hz(1000 rad/s)
this acceleration-level corresponds nicely to 10 mms velocity
and 10Ám displacement. A built-in control loop with small reference
transducer ensures the vibration level to be 10 m/s2 within ▒
3% for different transducer loads up to a weight of 150 gram.
The specially designed electromagnetic shakertable keeps the transverse
motion and distortion to an absolute minimum.
