What are the main features of a body scanner?
Summary: The application range of body scanners is very wide. Before using it, we need to know its characteristics so that we can apply it better. If you are interested in this topic, let's take a look!

Body scanners are widely used in various industries, so their uses are still very extensive. They can be seen in many industries. Moreover, body scanners use uncooled focal plane imaging, which is faster, non-contact, and more accurate than mechanical scanning. The imaging rate is 25 frames per second, which can adapt to fast rotary kilns. The furnace body can be rotated once to obtain multiple images. In this way, each measuring point can be located on the furnace body at 6cm*6cm, an area smaller than a person's palm. Even the shedding of refractory bricks can be accurately detected. Its characteristics are also reflected in synchronous imaging. The body scanner uses an industrial control computer above 586 to process data, and can display the temperature distribution of the entire kiln in real time. The color image is displayed on the monitor at a glance. A thermal image consists of 320*240 points, each point corresponding to a block on the kiln, so it can be used in multiple red kilns. For example, using an ordinary thermometer, due to the limitation of scanning speed, the thermometer will not monitor other parts of the kiln at the same time, while the body scanner is used for remote measurement of the entire furnace body and imaging at the same time, without missing any part, so that multiple red kilns and highlights can be monitored simultaneously.
The body scanner uses a high-sensitivity infrared detector with a temperature resolution of <0.5°C (200°C target). In this way, subtle changes in the combustion in the rotary kiln (especially the loss of local refractory bricks) can be reflected in time, and combined with thermal imaging system software, the trend can be predicted to avoid accidents, thereby reducing unnecessary downtime and refractory brick replacement. In addition, it makes good use of many computer technologies. The measurement data is fully digitized, and the digitized signals and various calculation results are displayed graphically on the monitor. The displayed color temperature distribution diagram directly displays the furnace skin temperature value or the furnace lining thickness. When used now, the operating status of the rotary kiln can also be recorded regularly. The calculation results and images of each thermal image can be recorded in the computer, and the body scanner can call up and replay existing records at any time. Therefore, the body scanner helps in data storage, retrieval, and management. In addition, the use of rich software will make historical records a powerful scientific basis for future analysis, argumentation, and decision-making.
