SL-2088 underground metal pipeline coating detection leak detector can not be excavated in the case of casing, convenient and accurate detection of underground metal pipe location, direction, depth, insulation coating size and other functions. To determine the effectiveness of the cathodic protection; on the main line of the branch to locate; to test the old pipeline to determine whether the need for overhaul of the pipe section; on the construction of the area (the construction of the pipeline to be completed); Section before the excavation of underground pipeline distribution inspection, to prevent the destruction of underground oil, gas, water, electricity and other pipelines.

'Features'
★ use of new digital filtering technology, can set the scope of leakage;
★ With a variety of detection methods, and automatic conversion. Transmitter battery voltage and automatic shutdown before the issue to the receiver prompt signal, the value is automatically saved when turned off.
★ It can automatically measure the resistance of the pipeline to the ground and output the signal to modulate the high-frequency alarm signal, the anti-interference ability is very strong.The transmitter output power can be adjusted automatically with the detection distance increasing.

'Detection principle and method'
Detecting the direction and buried depth of the principle and method: to the underground pipeline to send a specific high-frequency modulated signal by detecting the magnetic field of underground pipes to determine the location of the underground pipeline, direction and depth.
There are peak method and zero value method.
Detection principle and method: to the underground pipeline to send a specific high-frequency modulation signal, in the underground pipeline coating damage point and the earth to form a loop, and radiation to the ground, above the damaged radiation signal, according to this principle to find pipeline corrosion Layer of the damaged point.
The use of 'human capacitance method' is to do with the human body sensor leak detector components, when the leak detector went near the leak, the leak detector began to react when the leak came to the top, the speaker sound , Showing a large value, so as to accurately find the leakage point.
