  Calibration shake table  Volna VS4

The shake table is designed by the Equipment Development Bureau "Electra" (Irkutsk, Russia) for the seismic sensors, seismometers and accelerometers calibration. The shake table can set the harmonical occilations with the required frequency and amplitude for the sensors responce measurements.

The shake table set includes the table, the table control unit and generator (a DAC can be used instead of the analog generator). The data from the built-in displacement transducer and from the sensor outputs are to be acquired by a ADC (not included into the standard delivery set).

The shake table make both the horizontal and vertical occilations. The built-in displacement sensor is a high sensitive differential inductive displacement-to-frequency transducer. For the best measurements at high frequencies the shake table can be additionally supplied with an external reference accelerometer.
