Isolating Sub-Hertz Vibrations
DVIA-T is highly effective in isolating ultra-precision instruments from ambient vibrations ranging 1–10 Hz, where the vibration-sensitive precision instruments tend to be unstable and disruptive that cannot produce its optimal results. DVIA-T starts to isolate at 0.5 Hz, delivering 99% vibration isolation at 10 Hz.

The natural frequency of DVIA series is below 0.5 Hz, meaning that DVIA series effectively reduces low frequency vibrations in 1– 5 Hz, where passive isolation systems rather amplify the low frequency vibrations due to its higher natural frequency.
The active isolation systems are so much stiffer than passive isolation systems, the active isolation platform do not fluctuate like the pneumatic isolation platforms do. The active isolation system sustains its the maximum stiffness and stability; therefore, the top plate of the DVIA-T is resistant to vibrations as the feedback control system reduces the vibrations, ensuring the maximum stiffness and system stability.
DVIA-T is designed to incorporate a robust plug and play operation system for various applications. The plug & play system allows users to use all functions by simply plugging a power cable into AC power and pressing buttons.
A front LCD display allows users to monitor real-time vibration levels and a horizontal level.
DVIA Series uses the feedback control system to continuously detect vibrations disturbing an isolated surface and instantaneously react to minimize the vibrations in real-time. The feed-forward system is employed in DVIA Series to filter out floor vibrations in a predefined way.
Sensors and actuators that are integrated in the active vibration isolators, control vibrations in three translational degrees of motions ( X,Y and Z), and three rotational degrees of motions ( pitch, roll and yaw).
The smallest model is 420 mm×500 mm×93 mm, which weighs only 25 kg, allowing users to hand carry and install on any place at all.
If there are changes in an environment and location or placing other instruments, users can adjust a level of DVIA-T by simply pressing a button.
Metal springs are integrated in DVIA-T series as to reduce high frequency vibration and conveniently compressed air is not required.
With our GUI software and the integrated sensors allow users to monitor real time vibration levels and isolation performance. Furthermore, the software provides the optimized vibration solution by employing the software to tune the feedback and feedforward control systems according to users' instruments weight and environments, if required by users.
DVIA-TD is an ergonomic desk with integrated DVIA-T active systems, offering efficiency, comfort and low frequency vibration isolation performance in the working environment.
