FCST FCST-PUEM4 1.5-1.7m Extended Range Disk Markers

$25.23

FCST-PUEM4 Extended Range Disk Markers provide precision locating for underground flush-mounted facilities under backfill. Easily fastened to non-metallic lids, these IP68-rated HDPE markers offer a 1.7m max depth, 50-year service life, and cross-industry frequency compatibility (Gas, Telecom, Water) with 3M Dynatel series detectors.

Extended Detection Range: Achieves a maximum identification burial depth of up to 1.5 to 1.7 meters.

Rugged HDPE Packaging: High-Density Polyethylene shell delivers superior resistance to chemical corrosion and impacts.

Environmental Resilience: Certified IP68 waterproof rating; withstands extreme temperatures ranging from -20°C to 50°C (-4°F to 122°F). 

High Stress Resistance: Endures up to 5 KN of pressure without permanent damage, cracking, leaking, or RFID/electronic tag failure. 

Universal Detector Compatibility: Fully compatible with FCST-ED8000 or other industry-standard locators sharing the same frequencies (e.g., 3M™ Dynatel™ series). 

Cross-Industry Versatility: Tailored color and frequency configurations for Water, Sanitary, Telecom, Gas, Electricity, and Europower infrastructure.

To ensure optimal signal response and avoid electronic tag interference, follow these standard operating procedures:

1. Orientation: Install the electronic disk marker directly above the pipeline, keeping it as horizontal as possible.

2. Fixing to Non-Metallic Pipes: Attach directly to the pipeline and secure firmly with cable ties. Use sand or fine soil to fill gaps between the marker and the pipe to prevent uneven stress after backfilling.

3.Burial Depth Buffer: Considering later soil shifting, it is highly recommended to keep the burial depth within 80% of the maximum detectable depth.

4. Interference Prevention:Maintain a distance of greater than 1.5 meters between adjacent electronic markers to prevent signal overlap.

5. Metal Pipe Clearance: If marking a metal pipe, maintain a minimum vertical distance of 12 cm between the top of the pipe and the marker. Ensure NO metal objects cover the top of the marker.

6. Prohibition: Do not press or place the marker underneath the pipeline or the marked object.
