Vibrator Simulator simulates an actual servo hydraulic vibrator. This system is very useful in testing of Vibroseis control electronics, and in instructing of seismic personnel in the operation of Servo hydraulic Vibrators.
This system saves valuable production time by verifying proper operation of Vibrator Electronics and Vibrator Wiring.
