Electrical appliances are of great support to people in the workplace and in household conditions. Nowadays, there are inventions, capable of finding the wiring is located in a wall. Such instruments will be discussed further.
wire detector.
For the purchase of equipment to determine the flush, you need to know important information about them.
- when you buy should pay attention to the destination device.
- cheaper options detectors have limited functionality. Well suited for use in a domestic environment.
- acquiring the detector is important to consider its scope. Will it be used for professional purposes or household. This directly affects the price and functional features of the device.
There are several types of harness detectors.
electromagnetic
One of the most reliable and accurate detectors flush is a detector of electromagnetic action. Has a long service life, always gives precise measurement data. It defines only the wiring under load more than one kilowatt.
electrostatic
Pretty simple devices, but with great functionality. With the ease of wiring is energized. Disconnecting from the network wiring is not able to determine.
With the search function metal
It has the ability to detect metal residues in the wall. The advantages of the device may include wiring search without tension. On the downside - the discovery of nails, various metallic debris.
combined
These detectors have an advanced functionality. Include electromagnetic, electrostatic action function, can detect hidden metallic materials in the wall. The cost of these devices is higher than the rest.
General information about the detectors flush
Modern detectors may have additional functions, such as a laser meter or a level that makes them versatile devices.
Different models have different functionality and detection capability. For example, consider the model of the Russian manufacture DSL 8220S, which is able to find metal disposed to a depth of 21 cm. Upon detection of light takes place and a sound signal.
Bosch GSM 120 device company occupies a leading position in the class of instruments. It has the potential to determine the depth of various metals.
For detectors of the middle class can be safely attributed machine brand Black and Decker BDS200. The apparatus has a rugged housing which protects it from external influences. determining the depth of metal is relatively low.
You can also make the device detection flush with their own hands. For this we need a working ohmmeter transistor and charged smartphone. Once connected transistor ohmmeter will deflection. After entering the zone of the cable unit arrow ohmmeter make deflection before failure.
For the detection of wires hidden in the walls, you can use several ways to push back the purpose of buying the device in store.
Than to replace?
Search radio
This method is easy enough to define an open circuit or wiring. To do this, you must configure the radio to the radio wave and move parallel to the wall. At the point where there will be interference and background noise, there will be wiring or breakage.
Using the method of magnetic action.
Pretty simple search wiring in the wall. Suffice it to carry your smartphone with injected special application. After determining the wiring will be sent a signal to the smart phone, which is displayed on its screen.
Each determination wiring device must have certain functionality.
- alternating voltage with a range of 70-600 watts.
- component of the magnetic field should be greater than 0.5 mW / cm.
- in the configuration requires a power supply device.
- working temperature must fall within the interval 55 -10 degrees Celsius.
- detector must have the capability to measure resistance of 50 milliohms.
When choosing a flush of the detector can use the above recommendations. In general, the choice of the manufacturer and brand of the device should be guided by their own preferences.
