Dart Systems Flexitrace 9mm x 150m | Pipe Tracer System | Non-Metallic Utility Detection
You save £37.80 (5%)
The Dart Flexitrace 9mm x 150m Pipe Tracer System offers a professional-grade, one-person portable solution for identifying the path and depth of non-metallic buried utilities. Constructed with a glass fibre rod containing internal copper conductors housed in a polypropylene sheath, it serves as a highly efficient alternative to traditional sonde deployment. This system is specifically engineered to navigate pipes with diameters as small as 15mm, enabling precise location of obstructions, collapses, or entire duct paths when paired with a standard 33kHz signal generator.
Other lengths in this range:
- Dart Flexitrace 9mm × 50m
- Dart Flexitrace 9mm × 100m
- Dart Flexitrace 9mm × 120m
- Dart Flexitrace 9mm × 200m
How does the Flexitrace system locate non-metallic pipes?
By connecting a signal generator to the unit's terminals, the end coil is energized for Sonde Location or the entire 150m length is energized for Line Location when used with an earth stake. This allows a standard Cable Avoiding Tool (C.A.T.) to detect the signal through the ground at depths of up to 3 meters depending on soil conditions.
What are the primary construction features of the 9mm rod?
The system is built on a robust steel frame measuring 950mm x 820mm x 400mm and features a manual brake to maintain total control during deployment. The 9mm rod is reinforced with copper conductors, ensuring reliable signal transmission without the need for external batteries.
What pipe dimensions and frequencies are compatible?
This tracer system is optimized for use in ducts as small as 15mm in diameter and is fully compatible with any locator or transmitter operating at 33kHz. The integrated sonde housing at the tip measures 12mm Dia x 70mm, providing a compact profile for navigating tight bends.
