Analog Markers

MiM Marker 120 analog

An analog radio frequency marker is a passive electrical device designed for permanent marking of underground line structures. It provides a cheap and reliable marking for less significant points of an underground line structure. It is a good solution in cases where the required indication of significant strategic points underground line structure.

KOMPLEX® produces the following types of analogu markers:

• MiM Marker 120 analog
• MARKER 2500
• Long MARKER
• MAR 100-3D – ball marker

MiM Marker 120 analog Is a passive analog marker designed for the permanent marking of the underground facilities. The external diameter of the markers is only 12cm which means that the MiM Marker 120 analog can be used in the narrowest trenches or in the places with bad access. MiM Marker 120 analog represents the cost friendly and reliable way of marking all types of the underground facilities where the exact and clear detection is needed.

MiM Marker 120 analog is used for the straight-lined sections of the following underground facilities:
• gas pipelines
• optical and telecommunication cables
• sewage pipelines
• energy cables
• water pipelines
• etc

MAR 100-3D

MAR 100-3D is an analog ball marker. It is ideal for narrower trenches.
The biggest advantage of MAR 100-3D is the spherical nature of its electromagnetic field. This greatly simplifies the installation of the marker. The strong outer PE housing of MAR 100-3D provides high resistance to mechanical damage and protection in the most demanding conditions. Two holes on the sides of the marker's housing are intended for attaching MAR 100-3D to a line structure with fixing belts.

Analog RF markers

MARKER 2500, Long MARKER

KOMPLEX® produces two types of analog flat markers - MARKER 2500 and Long MARKER. Both markers provide a reliable and inexpensive way of marking underground line structures in cases where marking of a significant network point is not required.
Marker 2500 is designed to mark line structures at a maximum depth of 1.8 m. In the past, Marker 2500 was the most common method of marking all kinds of underground networks.

Technical Specification Of Marker 2500
Operating frequency (kHz) 83.0, 101.4, 121.6, 134.0, 145.7, 169.8
Outer housing material High Density PS
Dimensions       Diameter x Height   225 x 28 mm
Weight Max. 300 g (0,66lb)
Identification number ID NO
Marker read range 1,8 m (5,9ft)
Operating temperature -20 oC to +60 oC
Lifetime 50 years

 

Long Marker is novelty among flat analogue markers. Its advantage is a large reading range. The new design allows use of the marker down to a depth of 2.5 m.


Technical Specification Of Long Marker
Operating frequency (kHz) 83.0, 101.4, 121.6, 134.0, 145.7, 169.8
