Function and role of thermal imager

1. Temperature detection: The thermal imager can detect and measure the surface temperature of the object in real time, and find potential thermal problems, such as local overheating of the circuit, hot spots, etc.

2. Detection of hidden heat sources: Thermal imagers can find heat sources that cannot be seen or difficult to find by the human eye, such as hidden faults, water leakage problems, etc.

3. Environmental applications: Thermal imagers are not only suitable for industry and construction, but also widely used in meteorology, environmental protection and other fields. For example, water surface temperature, air temperature, etc. may be monitored.

4. Low energy consumption and high efficiency: Compared with other equipment, the thermal imager can quickly obtain the surface temperature information of the object in real time under the condition of low energy consumption, and improve the work efficiency.

Through the detection and processing of the radiation energy spectrum of the surface of the object, the thermal imager converts the thermal image of the object into a digital signal, which is finally visible on the screen, so that the problem can be found and located in time, and the subsequent maintenance and improvement work can be guided. It has wide practicability and high practical value.

Can a thermal imager penetrate a wall?

A thermal imager is an infrared camera that generates a temperature image by detecting thermal radiation. Since its detection range is infrared radiation, it cannot penetrate walls or other opaque objects. If the wall is opaque, the infrared signal will be blocked by the wall and cannot reach the target object, so that the thermal imaging image of the object cannot be obtained. Therefore, when using the thermal imager outdoors, you need to pay attention to whether there are obstructions around to ensure that the thermal imager can shoot towards the target object.

However, in some cases, the thermal imager can "see through" some thin, transparent objects, such as glass windows, plastic bags, gauze, etc. This is because these materials do not completely absorb infrared radiation, but partially pass through, so the thermal imager can detect the thermal radiation of the target object through these materials and generate the corresponding thermal imaging image. However, even if these transparent objects can be penetrated, part of the signal will be lost in their transmission process, so it is necessary to consider the signal-to-noise ratio and other issues.

Principle of thermal imager

The working principle of the thermal imager is to use the infrared radiation on the surface of the object to detect and convert it into an image. Mainly includes three steps:

1. Receive infrared radiation signals: The thermal imager can receive infrared radiation energy emitted from the surface of the object, which is difficult to be detected by the naked eye. Thermal imagers typically use infrared sensors to collect this infrared radiant energy and convert it into electrical signals.

2. Signal processing: The collected electrical signals need to be processed. These signals represent different thermal energy intensities and ranges. After processing, the signal can be converted into a meaningful infrared image.

3. Image display: The processed infrared image can be displayed on the screen of the thermal imager, usually in the form of a heat map. Areas of different colors represent ranges of different temperatures, so you can quickly see and locate temperature anomalies.

In short, the thermal imager can collect the infrared radiation energy emitted from the surface of the object, convert it into an electrical signal, and then process it into a meaningful imaging signal. Using this technology, temperature information can be obtained in real time and presented in the form of images, which provides a more efficient and high-quality detection method for various industries and scientific research.
