Infrared thermal imaging cameras are widely used in many fields, and choosing a suitable thermal imaging camera can greatly improve work efficiency. However, in the face of a wide range of thermal imaging cameras, how to choose the thermal imaging camera that suits you has become a difficult problem. The following are eight factors that need to be considered when choosing an infrared thermal imaging camera.
For handheld thermal imaging cameras, 160*120 is the golden resolution, which has a very good cost performance. The price of thermal imaging cameras with more than 1 million pixels is relatively high, unless you have high-resolution requirements, you can choose thermal imaging cameras with more than 1 million pixels.
Lens focal length
The lens of the general infrared thermal imaging camera can be replaced. However, the standard equipment of the manufacturer is usually a lens. The telephoto lens will improve the recognition rate at long distances, but will greatly reduce the field of view. On the contrary, the short-focus lens greatly improves the field of view, but it will reduce the recognition rate.
Image spacing, spatial resolution, the field of view, recognition distance
The indexes of image spacing, spatial resolution, the field of view, and identification distance are determined by the resolution of the detector and the focal length of the lens. In fact, the detector resolution and lens focal length of the infrared thermal imaging camera has fixed these four indicators, so you don't need to pay too much attention when purchasing. Therefore, the most important indicator of the thermal imaging camera is the resolution of the detector. In addition, the indicators mentioned above can all be changed by changing the lens.
The frame rate refers to the number of images that can be captured processed, and expressed by the thermal imager in one second. The faster the sensor responds and the higher the internal circuit processing rate, the greater the frame rate that can be achieved. The thermal imager with a high frame rate is suitable for capturing the temperature movement of high-speed objects and objects with high-speed temperature changes. The general TV frame rate is 25 Hz. According to the frame rate of the thermal imager, it can be divided into two categories: fast scan and slow scan. The equipment used in the power system, medical treatment, construction, and other fields generally uses fast scanning thermal imaging cameras, otherwise, it will bring some operational troubles. Generally speaking, the frame frequency of the infrared thermal imager should reach 30HZ, and the best one can reach 50HZ, otherwise, the infrared thermal imager will not be able to work well in many working situations. The frame rate directly shows the performance and response speed of the thermal imaging camera, and also directly affects the working efficiency of the infrared temperature camera.
Each model of temperature sensor camera has its own specific temperature measurement range. Therefore, the user's measured temperature range must be considered accurate, neither too narrow nor too wide. According to the law of black body radiation, the change in radiant energy caused by temperature in the short waveband of the spectrum will exceed the change in radiant energy caused by the emissivity error. Therefore, users only need to purchase an infrared thermal imager within their temperature measurement, and try to choose an infrared thermal imager with optional temperature measurement areas, and not only must be able to adapt to various temperature environments, but also ensure that the temperature measurement is accurate.
Temperature measurement accuracy
Generally, the temperature measurement accuracy of an infrared thermal imaging camera is ±2 of the possible reading accuracy of ±2℃, so there is basically no option.
Automatically track high and low temperatures
Automatically record high, low, average temperature, high and low-temperature sounds, and color alarms. This part will be very useful in actual use. Many medium models have this function.
Mobile temperature measurement point and temperature measurement area
Many infrared thermal imaging cameras do not have the function of moving the temperature measuring point and the temperature measuring area, but only have the function of measuring the temperature at the center point. This kind of infrared thermal imaging camera cannot automatically track high-temperature points. If the lens is not aimed at the high-temperature points, it will not be able to correctly capture the problem points. So this is also an important consideration when choosing an infrared thermal imaging camera.
A high-quality thermal imaging camera responds quickly and accurately in the process of monitoring the target, which can improve the accuracy and efficiency of the work, so we need to take these considerations into consideration when choosing.
