Passive Electrode Cables
AGI’s passive electrode cables are waterproof, multi-conductor cables used for resistivity measurements, self potential and induced polarization (IP) measurements. They require use of the Multi-Electrode SwitchBox, which houses all switching circuitry. The passive electrode cables are designed to be hard-wearing, and are designed with molded stainless steel (or graphite) electrode takeouts encapsulated in molding material that is chemically bonded to the outer and inner cable jacket. Unlike the unreliable connections made by lower cost plastic injection molded cables, the chemical bond in AGI cables creates a stronger more rugged and water proof electrode.
Passive Electrode Use Case
Passive electrode cables are ideal for lab experiments, surface measurements, and borehole-to-borehole measurements. Measuring between two boreholes, for example, gives you far better resolution than measuring from the surface alone, because the resolution increases when you put sensor electrodes closer to your target. You can deploy a passive electrode cable in a borehole for an extended period of time for effective time lapse monitoring and measurements.
