10000 Kgf Vibration System

The Water-cooled series Shakers are designed to test of most complex applications including DRDO, Avionics, ISRO, Military electronics and hazardous materials.

The hydrostatic bearing guidance of resin-bonded fiber reinforced armature coil takes care of both high and low acceleration tests supported with the pneumatic compensation for the armature.

Automatic pneumatic operated load compensation system employs latest micro-electronics & optical sensors built into the shaker which helps in realising nominal displacement at all payloads.

The shaker’s electromagnet is energized by the solid-state field power supply interlocked electronically to the amplifier console and is placed within the console to save space.

The Solid State, MOSFET/IGBT based, switching type, air cooled, matched with shaker to achieve the rated Sine, Random and Shock testing capabilities. Modular construction, Compatible with all standard Controllers.

Exemplary safety interlocks are logged on to the microcontroller based intelligent logic unit, which is most user-friendly in communicating the system status and operation.
