In order to meet the precise requirements of the laboratory, Liansheng Technology has developed an ultra-low frequency vibration isolation system below 1HZ. The LVC-100 can measure vibrations in both horizontal and vertical directions. Low frequency minimum can be measured to around 0.3Hz. This sensor can be placed directly on the ground, and combined with the VCM series of vibration isolators to form a feed-forward vibration isolation control device. After adding the LVC-100 low-frequency vibration isolator to the VCM series vibration isolator, there is a significant attenuation of low-frequency vibration, especially in the horizontal direction. It is a precise vibration isolation system for eliminating ground vibration of sensitive equipment in the complex environment of the laboratory.
