- The BSS-02B is a borehole probe used for the measurement of rock magnetic susceptibility to depths of 6000m. The sonde is mainly used for mineral exploration (uranium, iron, diamonds) or sedimentology.
- It comprises two sections: an aluminium cylindrical enclosure containing electronic circuitry, and a high-strength, non-magnetic enclosure where the detector is located. The electronics enclosure must be surrounded by a pressure enclosure, usually provided by a downhole logging system supplier alongside the transmission electronics.
- The sonde operates from an unregulated +15V nominal supply and provides an output in the form of a three-wire CMOS serial interace (for integration into your acquisition system) and a single wire pulse rate output for use with rate meters and counters.
