摘要： The measuring equipment used to determine the geological configuration ofthe sub-surface of a field using electrical means. Using a plurality of current and voltageelectrodes (15a, 15b; 16a, 16b) at specific mutual spacing and connected together bymeans of a trailer coupling (9) in the form, for example, a rope or cable pulled by atowing means (10). Is sent in the ground a lower electric current to 10 milliamps, notpresent a danger to technicians by the current electrodes (15a, 15b) and measuring thevoltage across the voltage electrodes (16a, 16b). In order to eliminate the risks causedby the current, the circuit comprises a limiter in the form, for example, a constant currentgenerator (17). In order to separate the useful signal, the voltage circuit includes abandpass filter (19 and 20). In addition, a single tip electrode amplifier (18) is integratedinto each of the voltage electrodes (16a and 16b). The method is effective to determinequickly and in detail the configuration of natural resource deposits, areas of moisture,sand locations and clay in construction areas of roads or buildings, as well as reserveswater and effluent discharges.
