Underground Pipeline Detector

Product Introduction

The Intelligent Pipeline Locator (also known as a pipe locator or path tracer) is a high-performance trenchless underground pipeline detection device that integrates path detection, cable identification and fault location. It consists of a transmitter, transmitting current clamp, receiver, flexible current clamp, connection test leads and an optional A-frame. It can complete path detection, general survey and depth measurement of metal pipelines and underground cables under trenchless conditions. The device adopts fully digital high-precision sampling and multi-stage filtering anti-interference technology, and features multiple modes such as classic localization, line cruise and signal distortion measurement. It supports 11 active and 3 passive detection frequencies. The transmitter supports three signal output methods - direct connection, coupling and induction - with adjustable digital power and built-in automatic matching and protection functions. Its cable identification function can accurately distinguish energized from de-energized cables, supports pre-calibration followed by remote identification, and automatically marks the target cable. Combined with a large-diameter flexible current clamp, it achieves non-contact safe detection. It is widely used in municipal planning, power supply operation and maintenance, and pipeline management and maintenance, and is an essential professional instrument for pipeline detection and maintenance.

Product Features

1. Multiple detection modes: classic localization mode, line cruise mode and signal distortion measurement mode.

2. Classic localization mode: compass, direction and signal amplitude display, intuitively showing the left-right direction of the pipeline.

3. Line cruise mode: 360° omnidirectional pipeline path indication, continuously displaying depth, current and relative pipeline position. The interface is simple and intuitive, requiring no experience to operate.

4. Signal distortion measurement mode: simultaneously displays peak and trough waveforms. At a distortion-free site, the peak and trough positions should be consistent, and the field shape should be symmetric about the centerline.

5. Current direction determination (for some frequencies): by calibrating the current direction, adjacent-line interference can be eliminated to prevent tracking errors.

6. Fully digital high-precision sampling processing: stable and reliable, ultra-high sensitivity, extremely narrow receiving passband and strong anti-interference capability, able to fully suppress the power-frequency and harmonic interference of adjacent operating cables and pipelines.

7. Multiple detection frequencies: 11 active detection frequencies and 3 passive detection frequencies.

8. Multiple transmitter signal output methods: direct connection output, clamp coupling and induction method.

9. Transmitter digital amplified power output, fully automatic impedance matching and fully automatic protection.
