Product Description


Features of the instrument

1. Using flat design, keyboard operation, onekey for multiple functions.

2. Without additional wiring, press themeasurement button to automatically measure parameters such as transmittingpower, transmitting voltage, transmitting current, and grounding resistance.

3. The signal strength of the whole process ofdetection is normalized by the internal circuit, so that the size of theleakage point and the insulation resistance of each test section arecomparable.

4. Using voltage-controlled vibration frequencytechnology, the signal strength response of tube location and leakage point isclearer.

5. Audio, indicating value, analog bar cursor,display signal strength more intuitively.

6. Easy to operate, simple to use, easy to learnand understand.

7. Small size, light weight, easy to carry, moresuitable for field detection. The instrument will automatically shut down whenthe voltage is insufficient, and the internal power supply will beautomatically cut off when the instrument is shut down. The energy savingeffect is significant.


Function and purpose:

--The buried pipeline detector can easily andaccurately detect the location, direction, depth, damage point of theanti-corrosion layer, the size of the damage, and the insulation resistance ofthe anti-corrosion layer.

--Complete acceptance of newly laid pipelines;

--Perform regular inspections on pipelinesaccording to safety regulations to determine the effect of cathodic protection;

--Locate the branch on the supervisor line;

--Inspect the old pipeline to determine the pipeline'santi-corrosion coating status

--Inspect the distribution of undergroundpipelines before excavation in the construction section to prevent damage tounderground oil, gas, water, and electricity pipelines during construction.

Features

--With multiple detection methods: and can beautomatically converted, the value is automatically saved when the machine isturned off.

--It can automatically measure the resistance ofthe pipeline to the ground, and the output signal modulates the high-frequencyalarm signal. The anti-interference ability is extremely strong, which improvesthe detection effect of the instrument and prolongs the battery life and life.

Detection principle and method :

--Principle and method of detecting directionand depth of buried soil: Send a specific high-frequency modulation signal tothe underground pipeline to determine the location, direction and depth of theunderground pipeline by detecting the magnetic field of the undergroundpipeline.

--Send a specific high-frequency modulationsignal to the underground pipeline to form a loop with the earth at the damagepoint of the underground pipeline's anti-corrosion layer, and radiate to theground. The radiation signal is strongest directly above the damage. Accordingto this principle, find the damage of the pipeline anti-corrosion layer point.

--Using the "human body capacitancemethod", the human body is used as the sensing element of the leakdetector. When the leak detector walks near the leak point, the leak detectoremits an audible prompt, and when the leak point is directly above, the soundin the horn *Beep, the indication value is *large, so as to accurately find theleakage point.
