When performing installation operations on existing structures, there is a risk of damaging internal wiring. Cable routes, communication networks and even pipelines are quite common filling of walls and ceilings in residential buildings and public buildings. Therefore, do not rush to create holes or perform other types of processing in structures that could potentially contain engineering conduits. A metal detector will help to insure against possible wiring violations, which, through sensors, detects foreign inclusions in the niche of building structures.
General information about wiring metal detectors
This type of tool refers to measuring instruments used in construction, households and industries. Its main function is to find hidden wiring in the wall, floor coverings, ceiling niches and other structures. Since in most cases we are talking about detecting metal elements that conduct current, such detectors can be considered primarily as an electrician's tool that can be used in installation work. Moreover, multifunctional devices of this type also allow you to determine indicatorshumidity and noise level in the area where electrical wiring is used. Such a survey, in particular, helps to identify the causes of short circuits in the walls.
It is worth noting the variety of materials that the detector can analyze. That is, not the target metal components of the wiring, but what the basis of the structure is formed from. It can be not only concrete with brick, but also wood, plastic and the same metal. For an accurate survey, you should choose the right tool, since the metal and hidden wiring detector is on the market in a large assortment. Models differ both in functionality and in key performance indicators.
Professional and household detectors
Entry-level models are designed to perform simple household tasks in the private sector. For example, if you need to drill a hole for the same pipeline, it will not be superfluous to initially scan the wall for electrical wires. Such models are designed to work with thin walls and partitions, so for large-scale events with alteration of massive structures, it is better not to use household metal detectors, the prices for which, however, are quite attractive - about 3 thousand rubles. A professional scanner of this type can cost 20-25 thousand, but its functionality is much wider. As practice shows, representatives of high-class detectors are able to detect metal parts in walls at a depth of about 50 cm.rods the device detects at a level of 80 mm.
Classification of the device by purpose
Metal can be different, it differs in quality characteristics, and may also have special performance properties. So, for example, in the same electrical wiring, it is important to take into account the magnetization of the material. There are devices that support the function of such an indication, but in household models, as a rule, this option is not available.
There are also special detectors that allow you to find rebar. Such a locator not only notifies the user about the presence of a target object in the wall, but also determines the size of the rod in the form of a diameter and its depth. But mostly builders use a universal metal detector that can detect nails, electrical wires, fittings, pipes, etc. with equal efficiency in the walls.
Reviews about the SKIL DT0551
The device is universal and is used by users from different areas - from professional organizations to households. In general, the owners of the device note satisfactory performance in terms of the accuracy of the analysis. The model works with copper, steel, distinguishes ferrous and non-ferrous metals under tension. That is, the device can be considered both as a full-fledged tool for an electrician, and as an assistant to a builder-installer. Although the device does not belong to the highest price segment, the manufacturer has implemented a lot of modern options in it.
Users themselves especially appreciate the possibility of automatic calibration andfast output of information on the electronic display. Thanks to the indicators, the operator can use the metal detector to determine the characteristics of the material, which is also important in the process of carrying out critical operations.
Reviews about the Bosch GMS 120
German measuring instruments occupy almost the leading positions in their segment. The GMS 120 model demonstrates a high class of metal detectors, which is confirmed by users. As the practice of operation shows, the device with high accuracy determines and fixes the location of metals with different characteristics both in concrete and in wooden structures. At the same time, the Bosch metal detector is provided with a simple interface, the convenience of which is emphasized by both professionals and amateurs. True, simplified control does not limit the operational capabilities of the device at all. The user has several modes of operation that allow you to separately scan drywall panels, metal and conductive elements.
Reviews about the model TESTBOY TB 26
In this case, we consider a multifunctional tester, focused specifically on working with network connections. The device is mainly used by professionals to check the correctness of connections, breaks and short circuits, as well as to determine the length of the traces. Despite the wide possibilities of operation, users note the small weight of the device. Calibration options are also highly rated,with which the metal detector is provided. Reviews indicate that the high-precision setting of the device allows you to determine with maximum accuracy the characteristics of wiring hidden in the wall and other structures.
How to choose the optimal model?
First of all, the scope of the device is highlighted. Determining the overall goal will allow you to figure out which segment is best to address. So, for occasional home use of the device in order to identify typical wiring, budget models worth 3-5 thousand are suitable. For work in professional construction, it is more expedient to prefer a metal detector with high performance. This applies to the depth of detection of wires, and to the ability of the device to determine the characteristics of detected objects.
Conclusion
If the first generations of building metal detectors performed only general functions of sensors that detect material with specific features, then modern devices provide extensive survey results. The level of occurrence, the properties of the material and its dimensions are the main data that professional metal detectors provide at the output. The prices for such devices are also rather big - the modification, average in terms of characteristics, costs 10-15 thousand. But entry-level devices are not deprived of functionality either. At a minimum, the budget model has several scanning modes that involve the use of special survey parameters for various objects - from building reinforcement to network cables.
