SS-BHV

The SS-BHV is a carrier designed to embeds different kinds of sensor like velocimeters (SS-45/20 or SS-10/08/02) and accelerometers (SA-10 or MEMS). The mechanical (passive spring) blocking system allows control of the sensor orientation up to 10-15 m from the surface. Other motorised lock systems allow deployment at high depth.
