Dual Sensor YS-A used in OBC, Transition Zone Sensor
The dual sensor of YS series is OBC seismic sensor used in ocean bottom, it presses the ghost reflection and the water reverberation and improves the accuracy of seismic data interpretation.
1. The unique design of the spring shock electrical connections makes the land seismic signal transmission more reliable.
2. Integrated design of hydrophone and geophone increases the ability of water proof and makes it possible for field maintenance.
3.Without gimber, magnetoelectric geophone gets rid of mechanical noise ,fully contacts with the sea bed, and effectively improves the coupling performance.
4.The creative gravity switch combination is used in electrical connections, and this gravity switch combination removes the mechanical noise which is caused by the spring piece(contact slip ring).
5.Flexible connections is used in order to adjust posture of this new composite geophone in water freely and also to lay and take back the cables in the operation easily.
