The Underground Electronic Marker (Non-ID Version) is a passive RFID buried positioning tag designed for underground utilities including gas, power, water supply, telecommunications, and sewage pipelines. It operates as part of a complete underground pipeline electronic marking system when used with a compatible pipe locator.
Core Advantages:
Long-Term Durability: Constructed with a high-density polyethylene (HDPE) sealed enclosure. It is waterproof, anti-corrosive, and high-temperature resistant (operating temperature: -20°C to 50°C). Rated IP68 for moisture and dust protection, it boasts a service life of over 50 years.
Depth Compatibility: Offers a maximum detection depth of 1.8 meters, meeting the burial requirements for most underground pipelines.
Passive Design: Features a built-in passive antenna and specific frequency resonant circuit. It requires no battery; instead, it is activated by the electromagnetic signal from a detector and reflects a signal for precise positioning.
Precise Positioning: The detector sends a specific frequency electromagnetic wave to activate the tag. By analyzing the reflected signal strength, the system determines the tag’s exact latitude/longitude and burial depth with minimal error and strong anti-interference capabilities.
Environmental Adaptability: With IP68 protection, it operates reliably in complex environments such as roads, green belts, and underground chambers, resisting water, corrosion, high temperatures, and dust.
Efficient Asset MANAGEMENT: Supports integration with GIS (Geographic Information Systems). During pre-burial, it can be bound to specific pipeline attributes (material, diameter, pressure, installation date), facilitating full lifecycle management.
Easy Installation: Designed for standardized deployment via "flat laying with cable ties" or "fine sand backfill," reducing labor costs and operational complexity.
