An 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, and so on. However, when using an infrared thermal imaging camera for fault detection, you must pay attention to the following three aspects, otherwise, it will be difficult to achieve accurate detection results.

Determine the maximum detectable distance

The maximum detectable distance of an infrared thermal imager is not a fixed data, and this distance is related to the size of the target to be 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 measured target is small, the detectable distance will be closer. 

Therefore, when we are measuring some small targets, we must first figure out what is the farthest temperature measurement distance of the infrared camera when measuring such a large target, to ensure that the temperature is detected within the effective distance, otherwise, the measurement results are also inaccurate.

Understand thermal sensitivity parameters

We know that the thermal sensitivity of a temperature sensor camera reflects the sensitivity of the thermal temperature camera to temperature. The lower the thermal sensitivity value, the stronger the thermal imager's ability to distinguish temperature differences. If we are interested in the slight temperature difference on the surface of the target to be measured, we must know the thermal sensitivity parameters of the thermal temperature camera. 

For example, an infrared temperature camera with thermal sensitivity of 0.04°C can distinguish a temperature difference of 0.04°C, while an infrared thermal imaging camera with thermal sensitivity of 0.07°C only can distinguish a temperature difference of 0.07°C. Only by understanding the thermal sensitivity parameters of the infrared camera, the most accurate data can be measured.

Adjust the focal length of the infrared camera correctly 

Nowadays, there are many types of infrared thermal imaging cameras on the market, some of which can be adjusted while others do not. For those thermal imaging cameras with adjustable focus, in order to obtain better measurement results, it is sometimes necessary to adjust the lens focal length according to the environment.

In addition to the above important points, we should also adjust the parameters of the infrared camera according to specific application scenarios to make the results more reliable and accurate.
