Description
Vesala EML9 EMS Marker Locator for Professional Detection of Underground Markers
The Vesala EML9 EMS Marker Locator is a lightweight and practical underground EMS marker locator. First, it helps technicians accurately detect buried markers used in telecommunications, fiber optic, power, water, natural gas, and CATV networks. In addition, it offers a metal detector function for locating large metal objects, such as manhole covers.
The EML9 is an economical and lightweight alternative to larger EMS tracers. At the same time, it supports all 9 main types of EMS markers used in the market. This allows professionals to work with a single instrument across different infrastructure applications.
EMS Marker Locator for Telecom, Fiber, Gas, Water, and Power
The Vesala EML9 detects EMS markers for many network categories. Specifically, it supports markers for power, water, European power marking, sewer, telecommunications, fiber optics, natural gas, cable TV, and general use. Therefore, it meets the needs of crews working on different underground networks.
In addition, the instrument helps technicians confirm the exact location of a target before excavation or technical work. This reduces the risk of damage to underground infrastructure and increases safety in the field.
Detection of Ball Markers up to 150 cm
The EMS Marker Locator from Vesala can detect common ball markers at a depth of up to approximately 150 cm, depending on soil conditions, marker type, and the measurement environment. At the same time, the audible signal and LED guidance help the user find the point where the signal is strongest.
As the technician approaches the target, the instrument increases the signal indication. This allows the user to locate the marker with greater confidence and reduce unnecessary trial attempts.
Support for 9 Types of EMS Markers
The Vesala EML9 covers all main industrial types of EMS markers. In addition, the user can select the operating mode according to the type of marker they want to locate. Therefore, the instrument adapts easily to different underground network tasks.
- Power: electrical energy.
- Water: water networks.
- European Power: European electrical energy marking
- Sanitary: sewerage.
- Telephone / Telecoms: telecommunications networks.
- Fiber Optic: fiber optic networks.
- Gas: natural gas networks.
- Cable TV: CATV networks.
- General: general use and special applications.
Metal Detector Function
In addition to EMS marker detection, the Vesala EML9 also features a metal detector function. This allows technicians to locate large metal objects, such as manhole covers and lids, under soil, asphalt, or ice.
However, the metal detector function is not intended for very small metal objects, such as coins or keys. Therefore, the user should use it mainly for large metal targets in technical field applications.
Clear Indication with Sound and LED
The EML9 guides the user with an audible signal and LED indication. As the signal becomes stronger, the technician understands that they are approaching the marker. In addition, the LED bar indicator helps quickly evaluate the signal strength.
At the same time, the adjustable volume and sensitivity settings allow more comfortable operation in different environments. For example, in noisy areas, an optional headset can be used so the technician can monitor the signal more effectively.
Lightweight and Practical Design for Field Work
The Vesala EML9 is designed for daily use in outdoor field work. In addition, the transceiver is compact, lightweight, and easy to carry. This allows technicians to work for longer periods with less fatigue.
The device has a protection rating of IP55, while it operates in temperatures from -10°C to +40°C. Therefore, it covers most professional use requirements on construction sites, roads, underground networks, and technical infrastructures.
Ideal for Preventing Damage Before Excavation
A key advantage of the Vesala EML9 is its ability to confirm the location of an underground target before excavation. First, the technician identifies the area where the marker is located. Then, they approach the point based on the signal indication.
In this way, the crew reduces the risk of damaging cables, pipes, or other underground installations. At the same time, the process becomes faster, more organized, and safer.
