Metal detector for detection of hidden wiring

When performing installation operations with the structures in operation, there is a risk of damaging the internal wiring. Cable routes, communication networks and even pipelines are quite common stuffing of walls and ceilings in residential buildings and public buildings. Therefore, you should not rush to create holes or perform other kinds of processing in structures that potentially can contain engineering channels. The metal detector, which by means of sensors detects foreign inclusions in the niche of building structures, will help to protect against possible wiring disruptions.

General information about the metal detectors of the wiring

This type of instrument refers to measuring instruments used in construction, household and manufacturing. Its main function is to find hidden wiring in the wall, flooring, ceiling niches and other structures. Since speech in most cases is about the identification of metallic elements conducting a current, such detectors can be considered primarily as an electrician tool that can be used in installation works. Moreover, multifunctional devices of this type also allow you to determine moisture indicators 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.

Separately it is worth noting the variety of materials that the detector can analyze. That is, not the target metal components of the wiring, but rather, from which the base of the structure is formed. It can be not only concrete with a brick, but also wood, plastic and the same metal. For an accurate examination, you should correctly approach the choice of the instrument, since the metal detector and the concealed wiring are presented in the market in a large assortment. The models differ both in terms of functionality and in terms of their main operational indicators.

Professional and household detectors

The entry-level models are designed to perform simple household tasks in a private household. For example, if you need to drill a hole to lay the same pipeline, it will not be superfluous to initially scan the wall for the presence of electrical wires. Such models are designed to work with thin walls and partitions, so for large-scale events with the reconstruction 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. At the same time, the device detects steel rods at a level of 80 mm.

Classification according to purpose

Metal is different, it differs in quality characteristics, and can also have special operational properties. So, for example, in the same wiring it is important to consider the magnetization of the material. There are devices that support the function of such indication, but in household models, as a rule, this option is not available.

There are also special detectors that allow you to find the armature. 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 the depth of its occurrence. But in general, builders use a universal metal detector that can detect with the same efficiency nails, electrical wires, fittings, pipes, etc., in the walls.

Reviews about SKIL DT0551

The device belongs to 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 accuracy of analysis. The model works with copper, steel, distinguishes between ferrous and non-ferrous metals that are under stress. That is, the device can be regarded as a full-fledged electrician tool, and as an assistant to the construction worker. Although the device does not belong to the highest price segment, the manufacturer has implemented many modern options in it.

Users themselves especially appreciate the ability to automatically calibrate and quickly output information to an electronic display. Thanks to the indicators, the operator can use a metal detector to determine the material's characteristics, which is also important in the course of carrying out the responsible measures.

Comments about the model Bosch GMS 120

German measuring instruments occupy almost the leading positions in their segment. The GMS 120 model demonstrates a high performance class of metal detectors, which is confirmed by users. As practice shows, the device with high accuracy determines and locates 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. The user is available several modes of operation, which allow separately to perform scanning of gypsum board panels, metal and conductive elements.

Reviews of the model TESTBOY TB 26

In this case, a multifunctional tester focused specifically on working with network connections is considered. The device is used mainly by professionals to check the correctness of connections, breaks and short circuits, as well as in determining the length of the traces. Despite the wide possibilities of exploitation, users note the small weight of the device. The calibration options provided by the metal detector are also highly appreciated. Feedback indicates that the high-precision tuning of the device allows you to determine the characteristics of the wiring concealed in the wall and other structures with maximum accuracy.

How to choose the best model?

First of all, the application area of the device is highlighted. The definition of a common goal will allow us to determine which segment is better to handle. So, for irregular home use of the device in order to identify typical wiring budget models worth 3-5 thousand will suit. For work in professional construction it is more expedient to prefer a metal detector with high operating parameters. This also applies to the depth of the wiring detection, and to the capabilities of the instrument to determine the characteristics of the detected objects.

Conclusion

If the first generations of building metal detectors performed only general functions of sensors detecting a material with specific characteristics, then modern devices give extensive survey results. The level of occurrence, the properties of the material and its dimensions are the main data provided by the professional metal detectors. The prices for such devices are also rather big - the average modification is worth 10-15 thousand. But the entry-level devices are not deprived of functionality. At a minimum, the budget model has several scanning modes, which involve the use of special survey parameters for different objects - from building fittings to network cables.
