Manufacturers of underground integrated pipeline detectors Manufacturers of underground integrated pipeline detectors Using methods of pipeline detectors Underground pipeline detectors have two working modes: passive working mode and active working mode. The passive working mode is used to search for a manufacturer of an underground integrated pipeline detector. How to use the pipeline detector. The underground pipeline detector has two working modes: passive working mode and active working mode. Passive mode of operation is used to search for unknown power lines in an area, while active mode of operation is used to track and locate transmitter signals.
Active mode applies the transmitter's specific frequency signal to the pipe and then uses the receiver to locate and track the pipe. The method can accurately locate, track and deepen the pipeline, and can also accurately locate and determine the size of the damage point of the anti-corrosion layer of the underground pipeline. If the dirt, paint and corrosion on the target pipe surface will create a large impedance, which will affect the transmitter to apply the signal to the target pipe, it should be avoided as much as possible.
Keep the ground rod as far away from the positioner as possible. Low frequency and high frequency selection tips: 1) Low frequency is suitable for long straight pipes with good conductivity. 2) High frequency is suitable for poor pipes (with gaskets, surface corrosion and local insulation).
High frequencies will jump over this barrier without losing signal. The disadvantage of high frequency signals is that there is a lot of interference (electromagnetic coupling) to the surrounding pipes. If multiple pipelines are present at the same time, it is recommended not to use high frequencies.
Used for non-metallic pipes, ditches, tunnels or places that cannot be detected by the first two modes, combined with pipe dredgers and pipe endoscopes for emission probe detection. This mode combines the above two modes, which can detect various metal pipes buried in the ground and accurately determine the specific position of a certain point of the underground pipe. What is the difference between a depth detector and an underground pipeline detector.
