The complexity of large underground utility networks is continually increasing. So 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 unique flexible operating modes to help you easily decide the right mode for your locating application and 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.

• Transmitter - The Sonel LKZ-2000 complete cable and pipe locator kit also includes a transmitter operating at frequencies of 512 Hz, 3140 Hz, 8192 Hz, 32768 Hz, 83.1 kHz, and 20 kHz. The power output has 5 levels, and the maximum power in the induction mode is 3 W. With galvanic isolation, the power reaches 12 W, assuming the impedance of the connected object is 100 Ω.
• Receiver - The receiver operating in passive mode (Power) uses frequencies of 50 Hz, 100 Hz, 450Hz/60Hz, 120 Hz and 540 Hz. The passive mode (Radio) is based on frequencies from 15 kHz to 60 kHz. The active mode with a transmitter offering frequencies of 512 Hz, 3140 Hz, 8192 Hz, 32768 Hz, and 83.1 kHz plays a key role. Antenna configuration is based on single peak value, double peak, null and full field.

In the Power mode, the measured depth range is up to 3 m, and in the Radio mode – up to 2 m. In the active mode with a transmitter, the depth measurement range is 4.6 m, and in probe mode – even 6 m.

It is also worth noting the accuracy of measurements. The measurement error does not exceed 5% of the depth in Line or Probe mode (from 0.2 m to 4.6 m) and 10% of the depth in Probe mode with a measurement at the depth of 4.6 m to 6 m. Due to the use of a Bluetooth communication interface, the transmitter can be controlled remotely. An auto-turn-off function has also been provided. The locator can work in temperatures from 20°C to 50°C. It can also operate at an angle, which allows detection to be performed under an obstacle such as a parked car or a building.

The receiver is operated with keyboard buttons that perform several functions, depending on the selected operating mode.

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

Power industry - 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.

Civil engineering and construction industries - 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.

Rail industry - 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.

Telecom industry - Tracing and locating large bundled cables, such as fiber optic cables, can be difficult and time-consuming. Sonel LKZ systems high-frequency modes are ideally suited for these types of od 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.

Gas and oil industries - 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.

Water industry - 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.

Companies dealing in power engineering, telecommunication or the widely defined construction industry encounter many problems related to underground power cables or other utilities. Refineries, water, and sewage management entities or repair companies need to know where their own or other cables are located, so as not to damage them during works. Sonel offers both widely used and renowned Sonel LKZ-1000 locators. Now Sonel is introducing a new model of the cable and pipe locator – Sonel LKZ 2000. It is a more advanced and more powerful tool, which proves to be much more efficient in difficult cases, but remains easy to operate and assists the operator with hints on further actions.

The locator’s receiver (LKO-2000) detects and tracks the routes of pipes, cables and other underground utilities conducting electricity. To guarantee a wide range of applications, it offers more than 70 frequencies and 4 operating modes (Power, Radio, Line, Probe). The central function is the noise measurement feature. The device scans the selected frequencies and indicates the ones which will be the most useful in the given location and rejects frequencies not recommended for the area. To increase localization efficiency, you should choose a frequency with the lowest noise possible. Visual and numerical noise level indications make it easier to select the right frequency. To allow for easier interpretation, the noise levels are displayed visually and numerically.

The locator transmitter (LKN-2000) is designed to generate signals in the target object. The generated signals are detected by the receiver (LKO-2000). What is important is the possibility of setting the device up in such a way that the signal is emitted at one of the 70 defined frequencies.

The high power output function is another usable solution. It allows a 12 W signal to be transmitted along an active line at a frequency of no more than 10 kHz. For example, this function is used to locate buried large-diameter steel pipes and to perform long-distance locates. For instance, it is estimated that if a Æ 300 mm iron pipe is buried at a depth of 1.5 to 2 m, the device, with its transmitter/ receiver frequency set to 640 Hz, can efficiently identify the localization at a distance above 5 km. Increasing the frequency to 8 kHz will reduce the distance by more than 1 km, while a further increase in the frequency to 33 kHz will enable the user to trace the pipe at a distance of approx. 1.5 km.

Line and Radio modes are based on active signals. It must be emphasized that active signals are placed on the target cable by the transmitter. The important features of the Line mode are galvanic isolation, induction clamping, and excitation induction. The line mode needs to be connected directly to the target line, and the current is transmitted to the line in the proximity of the transmitter. It should also be noted that in Radio mode, the signal is transmitted from an antenna located inside a non-metal tube.

The power mode uses passive signals and allows the receiver to trace live power cables with a voltage of 50 Hz or 60 Hz. The radio mode is also based on passive signals and enables the receiver to trace cables both receiving and emitting very low frequency (VLF) radio waves.
