AGI Active Electrode Cables

AGI’s Active Dual-Mode Electrode Cables (U.S. Patent 6,404,203) are used for ultra-sensitive automatic induced polarization (IP) measurements using nonpolarizable electrodes. The dual-mode electrodes have a receiver channel that is isolated from the transmitting stainless steel electrode.

Use Cases:

There are two main applications for dual-mode electrode cables:

• Mapping of dense nonaqueous phase liquid (DNAPL) spills in the ground. Such as:

  • Methylene chloride, used in processing chemicals and pharmaceuticals.

  • Perchloroethylene, used in dry cleaning and metal surface cleaning.

  • Trichlorethylene, used in refrigeration and HVAC systems.

• Mineral exploration

Product Features:

• Thick transmitter wires.

• Receiver wires are electrically shielded from the transmitter for a noise-free measurement.

• Internal kevlar-strength member.

• Distributed switching instead of a centralized switching box allows for thicker wires which will output more current.

• Transmits through the stainless steel stakes and receives through the non-polarizable electrodes for more sensitive measurements, especially during induced polarization (IP) surveys.

• Dual-mode electrodes with a patented separate receiving channel.

• Water-resistant.

Benefits Of Distributed Electrode Switching:

• Connect the instrument anywhere along the electrode cable

• No Switch Box needed

• Easier to perform roll-along survey without a switch box

• More depth penetration due to much less saw-tooth overlap pattern

• Thick transmitter conductors

• Shielded receiver conductors

• Two modes of operation:

  • Normal mode: collect data using only stainless steel electrodes

  • Dual mode: transmit on stainless steel electrodes and measure on separate non-polarizable electrodes
