How to use the pipeline detector The pipeline detector has two working modes: passive working mode and active working mode. Passive mode of operation is used to search for unknown power cables in an area, and active mode of operation is used to track and locate transmitter signals. The following are the methods of using the pipeline detector. The pipeline detector has two working modes: passive working mode and active working mode.

Passive mode of operation is used to search for unknown power cables in an area, and active mode of operation is used to track and locate transmitter signals. Let's take a look at how to use the pipeline detector. 1. Passive mode Passive working mode 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 obtain a suitable reading and select the maximum 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 receiver responds that there is a pipeline, stop immediately, pinpoint the location of the pipeline and mark it.

Trace and mark the first line that passes out of the search area. 2. Active mode The active mode is to apply the signal of a specific frequency sent by the transmitter to the pipeline, and then use the receiver to locate and track the pipeline. The active method can accurately locate, track and measure the pipeline, and can also accurately locate the damage point of the anti-corrosion layer of the underground pipeline and determine the size of the damage point of the anti-corrosion layer.

If the dirt, paint, and corrosion on the surface of the target pipeline will generate a large impedance, which will affect the transmitter to apply signals to the target pipeline, it should be avoided as much as possible. Keep the ground rod as far away from the locator as possible. I hope the above information about pipeline detectors can bring you some help. Thank you for reading.
