ED1100 Near surface marker



The ED1100 series marker adopts a nail shaped structure and is generally used to supplement the identification of buried pipelines or underground facilities, or to supplement the identification of crossing pipelines that are inconvenient for ground excavation. For newly built underground facilities or pipelines with shallow burial depth, they can also be installed together with these underground facilities or pipelines.

The ED1100 nail marker is designed and produced according to international standard frequencies, and is compatible with electronic marker locators designed and produced according to international standard frequencies (without ID mode). The ED1100 can also be equipped with RFID chips with two modulation modes, ASK and FSK, becoming electronic information markers. Through the ID number in the marker, ground detection personnel can clearly determine that what they have found is the target marker buried in advance, without suspecting whether it is an interference signal or an maker buried by other units. For ID markers, after obtaining the ID number, ground detection personnel can use the ID number to search for information related to the identified object stored in the cloud database (such as the type, specifications, and photos before covering with soil), which can achieve visual management of underground pipelines or facilities.

The ED1100ID-RW type marker, equipped with FSK RFID chips, also supports writing simple information such as marker type and specifications directly into the internal chip of the marker using the ED8000V400 version locator before covering soil. For remote areas with poor wireless signals, or for users who are unable to upload marked object information to the cloud due to information security factors, a more direct information management solution is provided.

Type and   specification of the identified object


During installation, use an impact drill to drill a hole in the concrete or asphalt pavement above the underground pipeline, insert a nail label into the hole, and then cover the hole with cement or asphalt.

According to importance, install vertically along the path with an interval of 10-20m, with a burial depth not exceeding 0.6m. The minimum horizontal distance between the marked object is 2.5cm, and the minimum distance between adjacent markers is 1m.
