How to apply an infrared meter to the wall warp?

Here's how to determine a straight line with an infrared level:

Place the spirit level on a flat plate (or machine tool rail) with a stable foundation and roughly level, and after the bubbles are stable, read at one end as the left end, and set it to zero. Then turn the level 180 degrees, still on the original position of the plate, after the bubble is stable, still at the original end (left end) reading a grid, the zero error of the level is half a grid. If the zero error exceeds the allowable range, the zero adjustment of the spirit level needs to be adjusted (adjust the screw or nut to reduce the zero error to within the allowable value.

For screws that are not adjusted according to the regulations, the nut shall not be twisted at will. Before adjustment, the working surface and plate of the level must be wiped and cleaned. After adjustment, parts such as screws or nuts must be tightened).

A spirit level is a commonly used measuring tool for measuring small angles. In the machinery industry and instrument manufacturing, it is used to measure the inclination angle relative to the horizontal position, the flatness and straightness of the guide rail of machine tool equipment, the horizontal position and vertical position of equipment installation, etc. According to the shape of the level, it can be divided into:

universal level, cylindrical level, integrated level, mini level, camera level, frame level, ruler level; According to the fixed way of level, it can be divided into: adjustable level and non-adjustable level.

To put it simply, it is to put the infrared in the middle of the wall foot, vertically hit the two ends, and then use aluminum alloy against the wall at both ends, look at the infrared light and the aluminum alloy outer mouth edge to be flush, and the middle of the wall is also down to see how much error with the two ends, there are errors that can be adjusted at the two ends, and the three points and one line can be adjusted. Then start to do it, adjust some quick-drying gypsum and put the aluminum alloy on the wall at two ends at speed, press to the upper and lower ends and infrared light flush, one person presses the batch, and waits for the dry to take down.

When the wall is under construction, it is basically necessary to level it first, but when leveling, I don't know what methods are used for infrared rays, as well as the steps of wall construction, so let's take a look.

The method of infrared wall leveling is used for determining the height of each surface layer, and the preparation method of the substrate obtained by subtracting the general layer thickness of infrared rays for the preparation method of the horizontal wall of the predetermined height, determining the height of the grounding layer.

1.The steps of wall construction in which the renovation is a difficult task and takes a long time, but the decoration has a comfortable and healthy environment. The atmosphere of the day is very cozy.

The wall decoration is actually very simple and can only solve 4 parts. Your home, new or old house renovation home whether to insert the wall design is the first step, a rough house do the developer trying to shovel the white wall, if the ball is a decoration of the quality of the wall of the old house, the good point is that the waterproof putty can do it yourself. When the infrared wall is leveled, if not, you have to remove the shovel.

2.The steps of wall construction are performed in which the walls are well treated to the subject, during which the first layer of the dust wall is treated with the primitive of the wall to maintain the basic level of the yin and yang of the wall of the DOS wall specification or the dough after the wall is rolled to improve the adhesion of the wall with gypsum washing, and finally, scratches the putty. The putty is now evenly spaced again evenly spaced by a basic putty away from the nalaiensi stirring for 5 minutes.

Stirring the electric stirrer, so that the first completely dissolved additives in the water and added to the storage directly ** material purchase mixing putty, can guide the water to the finished putty of the product, and subsequently ensure the film-forming properties and step quality.

3.The steps of wall construction are in which the scraper on the upper wall is scraped, and the construction is repeated when the powder is repeated, the thickness of the scraping single batch is greater than the scraping force in the scraping blood at one time, even if in one place, the wall putty construction is usually two first passes the second time, and the second pass is relatively small. It doesn't matter after the second pass.

4.The steps of wall construction are in it, and if it is usually putty powder, it should be done here. If it is waterproof putty, it should be sanded within 1-2 days. If the white wall can be completed, it is called after the wall is complete.

Through the above article, I believe that now you have the method of infrared wall leveling.

Generally speaking, the method of determining the height of ground leveling is to use an infrared level to make a horizontal line on the wall at a certain height of the ground, and then subtract the thickness of the floor to determine the height of each surface layer.

Infrared leveling, large-area planking: start from the side of the house and flatten it, and fix it on the wooden keel with stainless steel fasteners, with at least 3 fasteners for each board. Adjacent plate fasteners should be installed in a staggered manner.

The general woodworking MDF or sandwich panel can be completely leveled, and some public work, carpentry directly finishes the keel frame, and the infrared level can also be directly leveled.

Wall leveling: infrared positioning scanning, the wall deviation should be less than 1cm is better, and the excess size should be leveled with wooden square mat or putty.

You can use the vertical line function of infrared rays, take this line as the standard, and the height of the surface layer (tile or floor surface) is unified and coordinated, such as 12mm, the height of the surface layer, determine the height of the ground, and measure the height from the intersection of the vertical line and the elevation line downwards, and measure 45 cm from the elevation line downwards.

The operation is very simple, just follow the instructions.

The level is placed on a plate with a stable foundation and roughly horizontal, and after the bubbles are stabilized, it is read at one end as the left end, and it is set to zero.

The level is rotated 180 degrees, still placed on the original position of the plate, and after the bubble is stabilized, the zero error of the level is half of a grid when it is still read at the original end (left end). If the zero error exceeds the allowable range, it is necessary to adjust the adjustment screw or nut of the zero adjustment mechanism of the level to reduce the zero error to within the allowable value.

For screws that are not adjusted according to the regulations, the nuts shall not be twisted at will. Before adjustment, the working surface and plate of the level must be removed and wiped clean. After adjustment, parts such as screws or nuts must be tightened).

When the construction is pay-off, play one with 30 lines. The parallel line of the wall edge, where the infrared rays are placed, and then look at the distance from the wall to the perpendicular infrared rays. Look at a few more points.

At present, it is impossible for thermal imager products on the market to penetrate the wall, only to penetrate some plastic bags, etc., or to detect floor heating.

Infrared can't penetrate the wall, and there are no similar products at present, so I watch a lot of science fiction movies.

An infrared thermal imager is a detection device that detects infrared energy (heat) without contact, converts it into an electrical signal, and then generates a thermal image and temperature value on the display, and calculates the temperature value. Thermal imaging cameras are able to accurately quantify, or measure, the detected heat, enabling you to not only observe the thermal image, but also accurately identify and rigorously analyze the hot fault areas.

Once you know the principle, it's easy to shield the thermal imager, block you with an iron plate or wear clothes that reflect heat, such as clothes coated with aluminum foil or painted with silver powder, the reason is very simple, it depends on whether you want to destroy a set of clothes.

Just isolate the temperature of the wall.

This infrared thermal imaging camera doesn't seem to be able to pass through walls.

Laser level.

Functions: 1. The laser level can measure whether the plane is uneven 2. The output of the vertical plane and horizontal point of the laser.

3. There are horizontal beads on the laser level, which can measure whether the horizontal plane is level 4. There are LED lamp beads on the laser level and you can see the horizontal beads even at night 5. The laser level plus magnet adsorption function is more practical and convenient.

The function of the infrared level is to establish a reference level, which is used to measure the square of the house, and can only point the infrared light at the corner of the wall to see if the line is on the right line with the corner of the wall.

Of course, it is necessary to detect, otherwise there will be errors, and the measured data will be problematic.

Turn on the infrared.

The switch to put the infrared level.

Adjust the mold and smile flat - usually use the infrared level to stop the whistling, as soon as it is contained or when the light does not flicker.

At this point, click on the "V" symbol (button) on the level, so that a red line will appear on the wall in the up and down direction of the infrared shielding line, and this line is the vertical line.

Then use a pencil to draw a mark in the middle of the red line, remove the level, and then use the ink fountain.

Flick the ink line – the end.

As long as the heat can penetrate the surface, yes.

For example, when people wear clothes, they can basically see the whole human body with infrared imaging, and if they wear more clothes in winter, they can only see the head and hands, and there may be only a small amount of heat conduction to the surface of the clothes, at most they can see a faint outline.

Infrared imaging, which measures the "temperature of the outermost substance".

So I think it's not possible to see through walls, and it's hard to wear thicker clothes (unless the clothes have good thermal conductivity and can conduct people's body temperature to the surface of the clothes). Below is a picture of the human body taken with a red-eye camera** (in autumn, the clothes are a little thicker).

Some application scenarios will be checked with thermal imaging, such as floor heating, to see if the floor is hot, in fact, only the heat seeps out for the imager to perceive, the essence is "what penetrates what", the fact is that the heat penetrates the floor, not the infrared camera penetrates the floor.

For the answer of other netizens that "you can see through the wall", you can judge whether it is right or wrong. Grasping the essence of the principle is actually very easy to understand. Infrared imaging, which measures the "temperature of the surface of an object", can be used to infer what may be inside the surface temperature and thermal images of the object.

Infrared night vision devices include infrared thermal imagers, passive infrared night vision devices are also called infrared thermal imagers, but in fact, everyone calls passive infrared night vision devices infrared thermal imagers, thermal imagers can penetrate objects to a certain extent, but the object is too thick to penetrate, give you an example of penetrating the wall.

Detection of underfloor heating. Active infrared night vision devices cannot penetrate walls, and they must illuminate the target with an infrared searchlight to carry out imaging.

Infrared night vision device refers to using the machine itself to emit infrared shimmer light and then see the object clearly.

Thermal imagers, on the other hand, judge and see objects clearly by receiving infrared rays emitted by them.

Neither thermal imaging cameras nor infrared night vision devices are currently on the market that can penetrate walls. Through-the-wall can only consider higher-end products.

The thermal imager can see through the wall, and the domestic quality and reliable thermal imager is recommended by Arrow Optoelectronics. It is still the leading enterprise of the national nuclear high-tech base, which is relatively good and worth recommending!

Infrared, far infrared, are all light waves, infrared cannot penetrate cement, no matter how thin it is, unless it transmits light, far infrared is thermal radiation, thermal imaging is to detect surface thermal radiation, heat must be conducted to the surface to be detected, so thermal imaging cannot penetrate the wall, unless the heat source is conducted to the surface.

The corner of the wall should be square, and the infrared rays of more than five lines must be used to make the cross perpendicular line, and the distance from the relative perpendicular line to the side corner of the wall can be measured with a tape measure.

Answer: First of all, let's talk about the operation, before using the tripod of the green light level, try to adjust it to the visual horizontal position, and then turn on the power, turn on the switch, if the instrument tilt angle is larger, there will be an alarm, at this time rotate the leveling button for leveling, as long as the level is reached, there will be no alarm, at this time you can start to use, project the beam to the position where the construction is needed, and then along the beam can be very simple to complete the project. If you want to move the setting during the construction process, you must handle it gently, try not to shake the instrument to ensure its accuracy, and turn off the instrument before moving, so as to ensure the quality of the instrument.

Infrared thermal imagers cannot detect the human body through the wall, but can detect the source of fire.

A thermal imaging camera converts the invisible infrared energy emitted by an object into a visible thermal image.

The different colors on the top of the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the measured target can be observed, and the heat of the target can be studied, so as to judge the next step.

Modern thermal imaging cameras work by using optoelectronic devices to detect and measure radiation and establish an interrelationship between radiation and surface temperature. All objects above absolute zero (-273) emit infrared radiation.

The thermal imaging camera uses the infrared detector and the optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector, so as to obtain an infrared thermal image, which corresponds to the thermal distribution field on the surface of the object.

You can see people through the wall, and you can detect it through the person's body temperature, and I use a heat source human body sensor upstairs, and people can see it upstairs in any location, and you can know it with a middle finger, and the upstairs is very angry.
