Overview
Hospitality Enviro Tech’s Intelligent Underground Cable Path Locator is a very comprehensive path detection instrument. It has pipeline path detection, cable identification, fault search and other functions. The instrument is composed of transmitter, transmitting current clamp, receiver, receiving flexible current clamp, connecting test line, A-word frame (optional), etc.
Also, it can be used for pipeline survey and depth measurement of metal pipelines and underground cables under trenchless excavation. The instrument uses a variety of filtering technologies, has anti-interference ability, and can accurately locate and measure the depth. It is suitable for the detection and patrol of various underground metal pipeline, pipeline management and maintenance, municipal planning and construction, power supply and other departments, and is one of the necessary instruments of pipeline maintenance units. This function is realized by the signal transmitter, receiver, signal transmitting clamp and connecting test line.
Features
- Multiple detection modes: classical positioning mode, wire cruise mode, signal distortion measurement mode;
- Classic positioning mode: compass, direction and signal amplitude display, visually display the left and right direction of the pipeline。
- Lead cruise mode: 360 omnidirectional pipeline path indication, continuous display of depth, current, and pipeline relative position. The interface is simple and intuitive, and it can be operated without experience
- Signal distortion measurement mode: the peak and trough wave form should be displayed at the same time. In the field without distortion, the peak and valley value position should be consistent, and the field shape should be symmetrical relative to the control line.
- Current direction determination (partial frequency), can be calibration current direction, eliminate adjacent line interference, to prevent tracking errors.
- Fully digital high-precision sampling processing: stable and reliable, ultra-high
- sensitivity, extremely narrow reception frequency band, strong anti-interference ability, can fully inhibit the power frequency and harmonic interference of adjacent running cables and pipelines.
- Multiple detection frequencies: 11 active detection frequencies and 3 passive detection frequencies.
- Transmitter a variety of signal output: direct output, caliper coupling, induction method.

Scope 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 |

Flat position precision accuracy: Central axis position of the target cable or pipeline: ± 5% (buried depth in 0-3m) -10% (buried depth in 3m-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 |

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 transmitting power and frequency. The greater the power, the higher the frequency, the stronger the interference. The minimum distance of the receiver free from the transmitter interference often needs to be determined by test:
Utility 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 calibrable 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)
