Infrared thermometer takes you into the hot ground
With the arrival of the "information age", sensor technology, as a means of obtaining information, has made significant progress, and its application fields are becoming more and more widespread. The requirements for it are becoming higher and more urgent. Sensor technology has become one of the important indicators for measuring the level of scientific and technological development in a country. Therefore, it is very important to understand and master the basic structure, working principle, and characteristics of sensors.
The fiber optic online remote infrared thermometer has the characteristics of strong electromagnetic interference resistance, corrosion resistance, long transmission distance, and stable operation. The fiber optic online infrared thermometer can perform temperature detection in harsh and harsh environments and environments with strong electromagnetic interference. By utilizing its flexibility, the fiber optic online infrared thermometer can measure the temperature of objects that cannot be directly observed, such as the inner wall of containers or pipelines, and can withstand high ambient temperatures up to 200 ° C without the use of cooling devices.
Another thing is that the ground temperature is 33 ℃, and walking a few steps will make you sweat. Master Guo Shaozhu of the power company pointed to the wellhead and told reporters that the equipment on his back weighed a few kilograms. Walking alone on the ground with the equipment, he was already sweating profusely. The cable tunnel near Dongzhimen in Beijing is an old tunnel with a length of approximately four to five hundred meters. After opening the manhole cover, the reporter slowly descended along a ladder to the underground well several meters deep. The bottom of the well is slightly open, with a height of only a little over 1 meter. Cats can only walk forward with their backs. On both sides of the tunnel are rows of shelves, on which are cables with a thick and thin black outer skin at the mouth of the bowl. Within a few steps, the reporter felt suffocated in his chest, and sweat flowed down his neck, feeling as if he had entered the sauna.
