Pipeline detection
Detection range | Direct connection method: Generally, the cable length can reach
0~20 km, which is mainly determined by the ground resistance, cable
resistance and cable buried depth
Coupling method: Generally, the cable length can reach 0~10 km,
which is mainly determined by the ground resistance, cable
resistance and cable buried depth
Induction method: Applicable to cables buried less than 2m deep |
| Depth and Current | Real-time display of cable depth and current value |
| Pipeline measurement depth | 0-20m
|
| Depth Accuracy | Plane position precision: Center axis position of target cable or
pipeline: ±5% (buried depth 0-3m) -10% (buried depth 3m-20m) |
| True or False Tips | Eliminate interference from adjacent cables. When measuring
adjacent cables, the measurement of adjacent cables can be
distinguished based on the different signal strengths and measured
current phases fed back by the adjacent cables. In the process of
tracing the cables, observe the phase dial and pointer pointing to
distinguish the measured cable from the adjacent cables. |
| Sound Instructions | FM tone that varies with signal strength |
| Anti-interference display | Green: No interference Green: Good (results can be trusted) Red:
Severe interference (results cannot be trusted) |
| Anti-interference ability | The extremely narrow receiving frequency band and unique digital
processing method can fully suppress the power frequency and
harmonic interference of nearby running cables and pipelines. |
| Interference distance | When using the coupling method and the induction method, the
transmitter will generate interference within a short distance. The
interference distance is related to the transmission power and
frequency. The greater the power and the higher the frequency, the
stronger the interference.
The minimum distance at which the receiver is not interfered by the
transmitter often needs to be determined by experiment:
Pipeline detection: 5m away for the coupling method and 20m away
for the induction method can be confirmed as no interference
Cable identification: 2~5m away for the coupling method can be
confirmed as no interference |
| Cable identification | Identification method: Intelligent identification by flexible
clamps;
Number of cables that can be calibrated: 1 to 20;
Calibration value: The current percentage of the receiving signal
and the transmitting signal is between 75% and 135% of the
calibration value, which is one of the conditions for successful
identification;
Directionality: The transmitting clamp, the receiving clamp and the
loading signal must be in the same direction, which is one of the
conditions for successful identification. |
Cable identification
Detection range | Direct connection method: can identify signals with a loop
resistance of 0Ω to 8kΩ (usually can reach a cable length of 0 to
20 kilometers, mainly determined by the ground resistance and cable
resistance)
Coupling method: can identify signals with a loop resistance of 0Ω
to 1kΩ; (usually can reach a cable length of 0 to 6 kilometers,
mainly determined by the ground resistance and cable resistance) |
