Hydrophone completes BGK1000 to 4 components

The new hydrophone can be used in borehole sections where clamping is impossible. It has a flat frequency response from 10 Hz up to several kilohertz, see Data Sheet BGK1000-H.


The new geophone-hydrophone pair concept takes advantage of different signal properties of the recorded pressure waves. Downwave and upwave amplitudes are in phase when recorded by a hydrophone, and are in antiphase when recorded by a geophone.
