    Overview of Cable and Pipe Locator LKZ-2000

    Easily locate cables and pipes with pinpoint accuracy. The complexity of large underground utilities networks continually increase, therefor obtaining precise information on the location of specific buried cables and pipes has never been so important. To protect buried assets during ground excavation work and supporting the mapping and surveying of these existing utilities.

    Sonel LKZ-2000 system has a unique flexible operating modes to help you easily decide the right mode for your location application for the site conditions. The intelligent utility locator monitors the signal interference levels in all available modes and recommends which to use for the best results. Saving you time and giving you increased confidence in your results.

    Application for  Sonel LKZ-2000 - the best system for most challenging conditions!

    Sonel LKZ-2000 is designed to easily trace power cables over long and short distances with pinpoint accuracy, especially in areas with high levels of electrical interference. When used in conjunction with the supplied Multi Clamp a trace signal can be safely applied to an electrically live cable. The A-Frame accessory can also be used to easily locate cable sheath faults.

    The highly durable, weatherproof Sonel LKZ system has a flexible operating system to suit most site conditions and terrain, which is essential on complex and demanding civil engineering and construction sites.

    Damaging communication cables can be very costly and time consuming to repair, causing major disruption to the rail network. Sonel LKZ system is designed to easily locate and trace cables in congested areas and with high levels of electrical interference.

    Tracing and locating large bundled cables, such as fibre optic cables, can be difficult and time consuming. Sonel LKZ systems high frequency modes are ideally suited for these types odd cables, helping to improve your productivity and locating reliability of all cable types. The A-Frame accessory can be used to easily locate cable sheath faults.

    These can be the most potentially hazardous, costly or environmentally sensitive pipes to strike and therefore most important not to damage. Using the Sonel LKZ system’s range of low frequency modes, locating and tracing these pipes is easy over long distances, maintaining maximum accuracy.

    Locating and tracing pipes can support the mapping and surveying of utilities. Using the Sonel LKZ system with our dual frequency sonde is the ideal solution for locating deep underground non-metallic sewerage and drainage pipes, that can’t be detected using standard locating technology.

    Overview of LKZ-720 Wire and Pipe Locator

    Detect and trace cables in ceilings, walls and floors with the LKO-720 specially designed 3D antenna for precise wire tracing and determine of direction of wires in concrete up to 5 cm becomes a breeze.

    Locating power points and switches in buildings pulse generated by a LKN-720 transmitter with a specific frequency allows to
    locate and identify sockets and switches in live or dead (no current) circuits.

    Identify fuses on the distribution board with a precise sensor and additional contact and non-contact probes, identifying  breakers and fuses will be easily and save time.

    Possibility to trace in insulated conductors with C-8 clamp (purchased separately) used in the current mode or other mode forcing
    current, allows to uniquely identify wire or cable from a current signal.

    Non-contact detection of live cables allows to precisely detect energised wires in air and concrete without
    additional probes.
