The presence of moisture in building structures leads to damage to the building’s thermal insulation and corrosion, creating health and safety problems and increasing energy losses. Heavy rains and severe weather conditions affect buildings and structures. It is very difficult for construction workers and engineers to find all water leakage points with naked eyes. That is why they must use infrared moisture infiltration scans. It allows them to detect problem areas and make invisible wet areas visible to human eyes. Since the thermal imager is used as a regular video camera, the user can view large areas quickly.
Using A Thermal Imager
Thermal imagers are optoelectronic devices that detect IR radiation that is invisible to human vision. In any weather and light conditions, they detect objects that emit heat: people, animals, equipment, vehicles, or sources of fire. The thermal imager is not hindered by camouflage suits, bushes, and uneven fences. With the help of a thermal imager, you can see fresh tracks in the snow and residual heat. In conditions of dust and smoke, thermal imagers are indispensable for studying the space outside and inside the premises. They are available as portable devices and stationary devices.
The thermal imager captures the temperature difference between them and the background. It can be used during the day and in bright spotlighting, as it is impossible to “blind” it. It consists of a lens, an IR receiver (matrix), display, electronic system, controls, and data storage device. The lens focuses the radiation on the sensor, and the electronics process the information. The display shows an image that allows you to identify detected objects by their contours and color spectrum.
Search For Leaks In Roofs
It is tough to point out all moisture leaks in roofs with naked eyes. With thermal imaging equipment, professionals can quickly inspect flat roofs or roofs with a slight slope. Such surveys are a great way to reduce maintenance costs and extend the service life of flat roofs, thanks to the ability to detect moisture, which provides the necessary information for local repairs and detecting problems early. Building contractors and engineers use the obtained information to repair the roof and eliminate all leaks.
Restoration And Repair of Buildings
During the restoration process, a thermal imager can be extremely useful for finding hidden problems, helping to detect moisture that is invisible to the naked eye. You can analyze the data saved for repairs and insurance claims and save them to your computer. When the repair work comes to an end, you can reexamine the thermal imager to confirm the effectiveness of the repair. The images obtained at the beginning can be used for comparison to reduce liability for claims.
How Far Does The Thermal Imager See?
The maximum observation distance is one of the main criteria for choosing a thermal imager. It depends on the type and size of the matrix, pixel pitch, lens focal length, diversity, and the type and size of the object being observed. The range of the device must correspond to the scope of its application. Companies that offer infrared moisture intrusion inspection services use high-quality infrared thermal imaging tools to detect all possible moisture leak areas and help construction workers repair homes, roofs, walls, etc.
What Does The Image Quality Depend On?
The quality of the thermal image depends on the resolution, thermal sensitivity, and pixel size of the matrix. The higher these values, the better the image will be. The parameters of the lens and display, the distance and type of target, and the temperature contrast with the background are essential. However, high-sensitivity sensors and large lenses significantly affect the price of a thermal imager.
Thermal Imaging In Different Seasons And Times of Day
The thermal imager provides the best visibility at night and during the cold season. The temperature difference between heat sources and the background becomes more noticeable, making them easier to recognize. In summer, the temperature contrast between objects on the ground may be insignificant. So it is more challenging to determine heat sources. The thermal imager can be used during daylight hours.
Water leakage and moisture can be dangerous to buildings, walls, roofs, windows, etc. It is challenging to track all water leaks with naked eyes. Infrared moisture infiltration scans make it possible to find all moisture areas. Professionals conduct thermal imaging surveys and get accurate results. It makes building repairing and maintenance work an easy task for construction professionals.
