R30 Underground Cable & Pipeline Locator

The R30 Underground Cable & Pipeline Locator traces cable routes and measures depth up to 20 m before excavation — preventing utility strikes and enabling accurate fault location — factory direct at $4,200.

What Is the R30 Underground Cable & Pipeline Locator?

The R30 is a field instrument that traces the path and depth of underground cables and pipelines using active and passive detection methods. It operates in classic location, full-screen signal, and signal curve modes. Its 8 built-in receiving coils support route tracing, depth measurement, cable identification, and fault location.

Why Is Cable Route Location Critical Before Digging?

One mis-hit on an energized cable or gas pipeline can cost thousands in repairs — or cause a safety incident. Locating the exact route and depth before excavation protects crews and neighboring utilities. The R30 also verifies cable path before fault location, ensuring TDR readings are on the correct cable.

What Are the R30's Key Specifications?

The R30 detects routes up to 20 km (direct connection) with depth measurement to 20 m and fault location range up to 5 kΩ. It offers active frequencies from 512 Hz to 196 kHz plus passive 50/60 Hz modes. Current direction calibration prevents mis-tracking in congested duct runs.

How Does the R30 Improve Fault Location Accuracy?

Accurate fault location requires knowing the exact cable path and branches first — the R30 provides this mapping before TDR testing. Its real-time dynamic signal interference display helps operators distinguish the target cable from parallel utilities. The result is faster, safer fault location with fewer false dig points.

Key Features

• Route and depth detection, cable identification, and fault location
• Three testing modes: classic location, full-screen signal, signal curve
• Current direction calibration prevents mis-tracking
• Real-time dynamic signal interference display

Technical Specifications

Applicable Scenarios

• Pre-excavation cable path locating — trace routes before digging
• Pipeline depth measurement — confirm burial depth of gas/water pipes
• Shared utility duct survey — identify cables in congested ducts
• Utility damage prevention — prevent strikes on third-party services
• Land survey and as-built verification — confirm recorded positions

Testing Method

1. Select mode — passive for energized cables, active for de-energized
2. Connect transmitter — direct connect or clamp coupling
3. Trace the route — walk perpendicular; peak signal marks the path
4. Mark the path — flag the traced route every few meters
5. Measure depth — record values at key points
6. Confirm at joints — verify continuity at joint bays and terminations
7. Document — record path and depth for the excavation crew

Quality & Delivery

• 100% factory tested — calibration and test certificate included
• CE certified — EU compliance
• Export packaging — foam-lined transit case
• Lead time — 10–15 days
• After-sales — 1-year warranty, lifetime maintenance, free training
