I.Instrument Features

Multi-function

Transmitter function: it has three signal application modes: induction method, direct method and clamp method, which are suitable for different occasions.

Receiver function: it is used to measure the position, direction, buried depth and current in underground pipes and cables.

The left and right positioning arrows indicate the position of the target pipeline, and the positioning is fast and accurate; The front and back arrows and dB values indicate the location and size of the damaged point of the anticorrosive coating.

Special function of the receiver (optional A-frame): used for fault location (pipeline fault refers to the damage of the outer protective coating, cable fault refers to the damage of the outer protective coating) and detection of the insulation damage of the underground pipeline.

Current measurement: measure the current applied by the transmitter to the pipeline under test.

Multimeter function: can measure output voltage, line voltage, line current, impedance and power. Test the continuity and insulation quality of the cable before and after the cable fault finding.

External inductive clamp: suitable for places where the signal cannot be directly connected when detecting cables.

High positioning accuracy

A variety of measurement modes for pipeline positioning (valley mode, peak mode, broad peak mode, peak arrow mode), can verify each other to ensure the accuracy of pipeline positioning.

Maximum value method: Peak mode, broad peak mode, peak arrow mode

can be used to determine the horizontal component ( H X ) or horizontal gradient         ( DH X )changes, according to its maximum position to locate;

Minimal method: the use of the valley model, by measuring the vertical component  ( HZ )changes, according to its minimum position to locate.

Multi-Measuring depth method

With a variety of sounding methods can be arbitrarily optional, and can verify each other.

Double - level coil direct reading method;

Single - level coil 80% method, 50% method;

45 degree method.

Strong anti-interference

Observed parameters: both measured horizontal component ( H X ), vertical component ( HZ ) and can measure the level gradient (DH X).

Transmit power: the transmitter output power of 10W and continuously adjustable, according to the need to choose.

Working frequency:

Transmitter frequency:128Hz、512Hz、1KHz、2KHz、8KHz、33KHz、65KHz、83KHz。

Receiver frequency:radio、50Hz、100Hz、128Hz、512Hz、1KHz、2KHz、8KHz、33KHz、65KHz、83KHz。

According  to the target pipeline characteristics (material, structure, depth, length, etc.), the environment to select the appropriate operating frequency.

Easy to operate

Intuitive: the use of graphical display, can continue, real-time display of various parameters and signal strength detection process.

Auto: Automatically switches to dual-level antenna mode when measuring depth and automatically adjusts the receiver sensitivity to optimize the measurement signal and automatically recovers to the pre-sounding mode.

Continuous working time is long, the use of low cost

The transmitter is equipped with a large capacity lithium battery pack, a charge, to meet the field to detect a working day power supply needs, and can be recycled, greatly reducing the detection costs.

Transmitter AC and DC

Under normal circumstances, if the transmitter battery is sufficient, use the instrument built-in battery pack power supply. If you use the process, the transmitter battery power is low, but the detection task is not completed, you can directly external dedicated power adapter, the instrument can be used normally, without having to wait for the instrument to re-use.
