What precautions do you need to know when using an infrared thermal imaging camera?

The infrared thermal imaging camera is a very useful fault detection tool, such as electrical and mechanical fault detection, water pipe leakage detection, house mildew detection, etc. However, when using infrared thermal imaging cameras for fault detection, you must pay attention to three aspects, otherwise it will be difficult to achieve accurate detection results. So, what issues should we pay attention to when using an infrared thermal imaging camera?

First, you need to understand the maximum detectable distance of the infrared thermal imaging camera.

The maximum detectable distance of an infrared thermal imaging camera is not a fixed data. This distance is related to the size of the target being measured and the performance of the infrared detector. For the same infrared thermal imaging camera, if it is measuring a target with a relatively large area, the detectable distance will be farther; if the target being measured is small, the detectable distance will be closer. Therefore, when we measure some smaller targets, we must first figure out what is the furthest temperature measurement distance that the infrared thermal imaging camera can measure when measuring such a large target to ensure that the temperature is detected within an effective distance. Otherwise, the temperature will be measured within an effective distance. The results are also inaccurate.

Secondly, you need to understand the thermal sensitivity parameters of the infrared thermal imaging camera.

We know that the thermal sensitivity of an infrared thermal imager reflects the sensitivity of the thermal imager to temperature. The lower the thermal sensitivity value, the stronger the thermal imager's ability to resolve temperature differences. If we are interested in the subtle temperature difference on the surface of the measured target, we need to know the thermal sensitivity parameters of the infrared thermal imaging camera. For example, an infrared thermal imaging camera with a thermal sensitivity of 0.04°C can resolve a temperature difference of 0.04°C, while the thermal sensitivity is 0.07 An infrared thermal imaging camera with a temperature of 0.07°C can only detect a temperature difference of 0.07°C. Only by clearly understanding the thermal sensitivity parameters of the infrared thermal imaging camera can the most accurate data be measured.

Finally, adjust the focus of the infrared thermal imaging camera correctly.

Nowadays, there are many types of infrared thermal imaging cameras on the market. Some can adjust the focus, while others do not. For those infrared thermal imaging cameras with adjustable focus, in order to obtain better measurement results, it is sometimes necessary to adjust the lens focus according to the environment. Everyone should pay special attention to this aspect.

To sum up, here are three issues to pay attention to when using infrared thermal imaging cameras. Of course, there are many other details that need to be paid attention to, but these three points are more important and should attract everyone's attention.
