The BSS-02B magnetic susceptibility borehole sonde is used in
mineral exploration, particularly for discrimination of kimberlites in diamond
exploration, and for stratigraphic correlation to depths of 6000
metres.
The sonde has a diameter of 43mm and is designed and calibrated
for a 50mm borehole. Rated at 120°C, 10,000psi.
The sonde comprises two
sections, an aluminium alloy cylindrical enclosure containing electronic
circuitry and a high-strength non-magnetic enclosure in which the detector is
located.
The sonde operates from an unregulated 15V nominal supply and
provides an output in the form of a three-wire CMOS serial interface for
integration into the client's data acquisition system.
