damaged points while electric cable breakdowns refer to the outer layer damages.); detecting the insulation
damages of underground pipeline and cable.
8) Measuring the current of the pipeline and cable applied by the transmitter.
9) Multimeter function: measure the output voltage, line voltage, line current, impedance and power; Test
the cable continuity and insulation quality before and after cable fault finding.
10) External induction clamp: suitable for testing the cable when they cannot be directly applied to the
signal of the place.
2. High Location 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.
1) Maximum value method: peak mode, broad peak mode and peak arrow mode are available to
determine the horizontal component (
) or horizontal gradient (
) changes, according to its
maximum position to locate;
2)
Minimum value method: use the valley mode by measuring the vertical component (
) changes
according to its minimum position to locate.
3. Measuring the depth
A variety of methods can be used to verify each other.
1) double-level coil direct reading method;
2) single-level coil 80% method, 50% method;
3) 45 degrees method
4. Strong anti-interference ability
1) Many Observation Parameters: can measure horizontal component (
), vertical
component (
) and horizontal gradient (
).
2) Large transmission power: the transmitter output power reaches 10W and it could be
continuously adjustable.
3) Multiple 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 features (material, structure, depth, length, etc.) and the
environment
to select the appropriate operating frequency.
5. Easy Operation
