Performance
The diagrams below show the performance of the SE-29 and SE-29T for operation alternating between 10 minutes at full load and 10 minute breaks (blue graph). Performance may vary for different cycles. The yellow graph shows acceleration values that can be safely used during continuous operation.
At 2 kHz, you can see a boost in the maximum acceleration. This is due to a new bearing design which minimizes transverse motion over the whole frequency range and reduces the moving mass above 2 kHz, thereby allowing for increased acceleration at equal force.
CS Q-LEAP™ SINE with SE-29
The CS Q-LEAP™ system is used for vibration calibration of a wide range of sensors including vibration sensors and measurement systems from 3 Hz...20 kHz. It is based on the HERO™ vibration controller and the SE-29 high-frequency vibration exciter.
