How to make a hidden wiring indicator

When performing construction work, there is often a need to check the wall for the presence of wiring in it. A detector that reacts to metal is needed to perform the search. It is possible to purchase this device in the factory version or to make the finder of concealed wiring by own hands. This article will discuss the nuances of the internal device of detectors, as well as the ways of their manufacture.

How to make a hidden wiring indicator

Circuits of factory detectors there are several types of factory production detectors: electrostatic. The advantages of such a device in the simplicity of the internal device and the ability to find metal objects at a significant distance. The drawback of the detector is the ability to search only in a dry environment. Otherwise, false positives will occur. In addition, only those wires that are under voltage can be found. Electromagnetic.

Advantages are in simple scheme and high-precision detection of wiring. The drawback is only, but essential: in addition to the voltage, you need a rather powerful load-not less than 1 kilowatt. Detector. Such a device is a standard metal detector. The main advantage in the absence of the need for tension. Disadvantages: Detects any metal (not just wiring), as well as structurally complex.
