The detector of concealed wiring is a necessary assistant in repair
Repair in the house, even if you want to avoid it,- the event is almost inevitable. There is always a desire to improve, change or add something. But before starting any repair work, you need to take care of your own safety, as well as preserve the integrity of what has already been done. If the wiring
Detector for detection of hidden wiringIt is a device that determines the presence of electrical wires in the walls. It is necessary for repair work in the premises where the laying of electric lines is performed inside the walls, and visual inspection does not give absolute certainty in its strictly defined location. The general principle of this kind of device is that when electromagnetic waves are captured, they give out an alert signal. And since the electromagnetic waves of the wall do not pose a great deal of interference, the detector makes it possible to accurately determine their source, that is, the cable.
Use such a device is very simple. First turn on the hidden detector. Then hold them along the wall in the area where drilling or other work will be performed that can damage
All detectors can be divided into three classes:
- Electrostatic. Any concealed wiring detector of this type is easy to handle and is able to detect the cable at a sufficiently large distance from itself. But he is not deprived of the shortcomings. First, this type of device will be ineffective if the walls are metal or wet. In this case, it will show that the wiring is located on the entire wall. Secondly, the drawbacks can be added the fact that it will not work if the cable is not live.
- Electromagnetic. Such a hidden detector allows you to find the cable in the wall with very high accuracy. However, it is also very simple to handle. But, unfortunately, for its effective operation it is required to have a voltage on the wire and a connected load of the order of a kilowatt.
- Metal detectors.
As can be seen, each of the detectors has its ownDeficiencies that may interfere with the effective search for the wiring. Combining all three types of devices in one allows to increase the probability of accurate detection of cables in the wall. Virtually every manufacturer of such measuring equipment produces universal products. For example, the Bosch "GMS-120" concealed wiring detector, which allows you to search not only electrical cables and metals in the wall, but also wooden structures. And with such a device or analogue of another manufacturer, the chance of accidentally stumbling onto electric wires is much less.
