DoReMi downhole

SSBH sensor is a geophysical device designed to measure vibrations in boreholes for DownHole, UpHole and CrossHole
surveys. Made from stainless steel, it is robust and rugged, and can be equipped with 4.5, 8 or 10Hz geophone sensors.
It can be used with any exploration seismograph and, naturally, with all our seismographs, especially the DoReMitm system.

Description

The SSBH sensors is designed mainly to measure soil properties as per Vs30 calculation.

Downhole
Injecting energy from the surface you can measure the travel time of P waves and SH waves and then calculate the elasto-mechanic properties of soil.
Crosshole
Using a proper borehole source of mechanical pulses to be put at the same depth of receiver and/or measuring wit a variatey of depths for both direct measuremen of P wave speed and S wave speed can be accurately accomplished.

Some customization can be applied to the sensor for example connecting rods to use 2 sensors as a double body sensors to measure the differential time arrivals.
