Overview
Brief introduction: The characteristics of FJ-6 underground pipeline detector are: 1. It adopts a flat design, keyboard operation, and one click multi use. 2. Without the need for additional wiring, simply press the measurement button to automatically measure parameters such as transmission power, transmission voltage, transmission current, and grounding resistance. 3. The signal strength of the entire detection process is normalized by the internal circuit to ensure comparability of the leakage point size and insulation resistance value of the anti-corrosion layer in each measurement section. 4. Adopting voltage controlled vibration frequency technology to make the signal strength response of pipe position and leakage point clearer. 5. Sound system, indication, analog bar cursor, display signal strength more intuitively. 6. Easy to operate, simple to use, easy to learn and understand. 7. Small size, light weight, easy to carry, and more suitable for field testing. 8. When the instrument voltage is insufficient, it automatically shuts down, and when it shuts down, it automatically cuts off the internal power supply, which can save energy.

[Function and Purpose]
Function of FJ-6 underground pipeline detector:
★ This instrument can easily detect the location, direction, depth, damage points and size of the anti-corrosion layer of buried pipelines, as well as the insulation resistance of the anti-corrosion layer, without excavating the covering soil.
FJ-6 Underground Pipeline Detector Purpose:
Conduct pipeline acceptance according to SYJN4029-88 and GJJ33089 standards;
Conduct final acceptance of newly laid pipelines;
Regularly inspect pipelines according to safety regulations to determine the effectiveness of cathodic protection;
★ Locate the branches on the supervisory line;
★ Conduct inspections on old pipelines to determine the condition of their anti-corrosion coatings;
Before excavating and breaking soil in the construction section, inspect the distribution of underground pipelines to prevent damage to underground oil, gas, water, electricity and other pipelines during construction.
[Features]
★ It has multiple detection methods: it can automatically switch and save values automatically when turned off.
★ It can automatically measure the ground resistance of the pipeline, output low-frequency modulation alarm signals, and has strong anti-interference ability, improving the detection effect of the instrument and extending the service life and lifespan of the battery.
★ Voltage regulator chip 2930T ensures more stable signal reception at the receiver;
The intelligent power protection system of the transmitter prevents the instrument from working under overload and can automatically reduce the power level of the transmitter;
★ Fully enclosed assembly method for transmitter, IP67 dustproof and waterproof rating
[Detection Principle and Method]
The principle and method of detecting the direction and burial depth: sending specific low-frequency modulation signals to underground pipelines to determine their position, direction, and depth by detecting the magnetic field of the underground pipelines.
Detection principle and method:
Send a specific low-frequency modulation signal to the underground pipeline, form a loop with the ground at the point of damage to the anti-corrosion layer of the underground pipeline, and radiate to the ground. Radiate the signal * strongly directly above the damage, and use this principle to identify the point of damage to the pipeline anti-corrosion layer.
★ Adopting the "human body capacitance method", which uses the human body as the sensing element of the leak detector. When the leak detector walks near the leak point, the leak detector emits a sound prompt. When it reaches directly above the leak point, the sound in the horn is * *, and the reading is * *, thus finding the leak corrosion point.
