The YNGX-H pipeline detector is a high-tech product designed based on the reflection principle of electromagnetic waves in the transmission process and the principle of electromagnetic induction, combined with digital filtering, wireless reception, and software control.

Electromagnetic induction: The basic working principle is: the transmitter generates electric and magnetic waves and transmits the signal to the underground metal pipeline to be detected through different transmission connection methods. After the metal pipeline induces electromagnetic waves, an induced current is generated on the surface of the cable. The induced current will propagate far away along the metal cable. During the propagation of the current, electromagnetic waves will be radiated to the ground through the cable, so that when the local metal pipeline tester receiver detects on the ground, it will The ground directly above the underground metal pipeline receives electromagnetic wave signals, and the position and direction of the underground metal pipeline can be determined by the changes in the strength of the received signal. As shown below:

The conditions for the realization of this principle: First, there must be a signal source that can emit enough power to form a current in a line capable of transmitting power, and the current will generate a magnetic field around the line during the flow; secondly, there must be a signal source that can receive this specific The electric circuit of the magnetic field displays the change process of the magnetic field in the form of electrical signals.

1. Transmitter characteristics

1) With user-friendly software and full Chinese menu. The button definition is simple and clear. The measurement method is simple and fast.

2) Constant power output and automatic matching to ensure that the machine is working in good condition. The built-in insulation loop resistance meter function can automatically measure the loop impedance of the metal pipeline to the ground and between phases, which can assist in judging the insulation properties of the metal pipeline.

3) The success rate, test accuracy and test convenience of finding the metal pipeline path are better than any domestic testing equipment.

4) The instrument has powerful data processing capabilities and a friendly display interface

5) Built-in lithium battery for power supply, which can test the routing of metal pipelines in a no-power environment to ensure daily work.

2. Features of the receiver

1) Portable, lightweight, easy to use, powered by a rechargeable lithium battery, can be operated by one person, and simple to use.

2) Digital design, software control, stable and reliable performance. ...

3) The measured information is provided to the operator in three ways: the number size, the length of the lifting grating, and the sound speed, so that the test process is easy and free.

4) The receiver has functions such as power shortage alarm and automatic shutdown protection.

5) The receiver can be connected to the A word or the detection rod adopts the step voltage legal point.

6) The receiver can be equipped with identification receiving coupling clamp for pipeline identification.
