VT-6 series servo-vibration controller integrates the capacity of servo-valve control and vibration control together innovatively and powerfully. It features HVS series servo-hydraulic vibration testing system to be delivered with compact design, simpler connecting in loop control, easy in installation and operation.

Based on advanced digital control and PID algorithms, VT-6 composes of double loop controls, displacement and acceleration, at same time. This makes servo-hydraulic shaker under a stable, reliable and precise control, with better frequency response and wider usable range.

VT-6 is a PC independent controller, all operation of the vibration system is performed through the VT-6 software computed by on board DSP. Its hardware has considerable design in connecting with different types displacement sensor and accelerometers. VT-6 is fully compliant with all servo-hydraulic vibration systems from other vendors.
