Pipeline detection

Range of detection

Direct connection method: generally can reach the cable length of 0~20 kilometers, mainly determined by the grounding resistance, cable resistance and cable buried depth

Coupling method: generally can reach the length of the cable 0~10 kilometers, mainly determined by the grounding resistance, cable resistance and cable buried depth

Induction method: suitable for cables with buried depth less than 2m

Depth and current

Display the cable depth and current value in real time

Pipeline measurement depth

0-20m

Deep precision

Plane position precision accuracy: the central axis position of the target cable or line:

±5%(Buried deep in0-3m)-10%(Buried deep in3m-20m)

Positive and wrong prompt

Excluding the interference of adjacent cables, in the measurement of adjacent cables, the measurement of the adjacent cables can be distinguished according to the different signal strength and the measured current phase of the adjacent cables. In the process of tracking the cables, the phase dial and pointer can be observed to distinguish the measured cables and the adjacent cables

Sound instructions

FM tone with signal intensity

 capacity of resisting disturbance

Very narrow receiving frequency band and unique digital processing method can fully suppress the power frequency and harmonic interference of adjacent operating cables and pipelines

 interference distance

When using the coupling method and the induction method, the transmitter will produce interference in close distance. The distance of interference is related to the transmission power and frequency. The greater the power, the higher the frequency, the stronger the interference.

The minimum distance of the receiver without disturbed by the transmitter often needs to be determined by test:

Pipeline detection: 5m away, 20m away as no interference Cable identification: the coupling method beyond 2~5m can be confirmed as no interference

Cable identification

Identification mode: flexible caliper intelligent identification;

Number of calibrate cables: 1~20;

Calibration value: the current percentage of the received signal and the transmitted signal between 75% and 135% of the calibration value is one of the conditions for successful identification;

Directionality: the transmitter clamp, receiver clamp must be in the same direction as the loading signal, which is one of the conditions for successful identification

Cable identification

Range of detection

Direct connection method: can identify the signal with a circuit resistance of 0 Ω ~ 8 kΩ (generally, the length of the cable can reach 0~20 km, mainly determined by the grounding resistance and cable resistance)

Coupling method: can identify the signal with circuit resistance of 0 Ω ~ 1 kΩ; (generally the cable length is 0~6 km, mainly determined by the grounding resistance and cable resistance)
