Underground Pipeline Detector Underground Pipeline Detector Field Source has two working modes. Underground pipeline detector passive source working mode is used to search for unknown power cables or underground pipes with cathodic protection signals applied in an area and metals that can sense radio frequencies. Pipeline, active source working mode is used to track and locate pipeline signals in the area. 1. The passive source power frequency method does not require a transmitter, it can search for power cables in an unknown area. Turn on the receiver, select the working frequency of the receiver as 50Hz, adjust the gain to get a suitable reading and select the maximum value method or the minimum value method to search back and forth in an area by grid search.
Carry the receiver and walk smoothly, so that the fuselage surface is in a straight line with the moving direction and at right angles to the passing pipeline as much as possible. Do not swing in an arc, because this will produce some misleading signals. When the response of the receiver shows abnormality, stop immediately, accurately locate the position of the pipeline and make a mark. A pipeline passing through the search area also needs to be tracked and marked.
Underground pipeline detector 2. The passive source cathodic protection current (CPS) signal method does not require a transmitter, it can search for underground metal pipelines with impressed current cathodic protection in an unknown area. Turn on the receiver, select the receiver working frequency as CPS, the usage method is the same as the power frequency method. 3. Radio frequency detection mode: The radio frequency detection mode is mainly used in the detection of metal pipelines that can sense radio frequencies.
