Vibration Isolation Solutions

LFS-3 Low Frequency Sensor

The LFS-3 low frequency sensor measures horizontal and vertical accelerations in three axes down to frequencies of about 0.2Hz. The sensor is placed directly on the floor and is used in a feed forward loop in combination with standard AVI/LP systems to increase the vibration isolation at very low frequencies. The LFS can be retro-fitted to existing AVI-LP systems.
