What is an explosion-proof camera and how to choose it?

As for the explosion-proof thermal imaging camera, you probably don't know what it can be used for after its normal use, and you don't know where to start when you buy it. Today, Captain Li will take you to know about the use and purchase points of explosion-proof thermal imaging cameras.

Let's first understand what explosion-proof thermal imaging cameras can do.

Infrared thermal imaging technology plays an increasingly important role in all sectors of the national economy, and its application fields are also expanding: it was used in the military in the early days, and then it began to be used in industrial, agricultural and civil markets with the continuous development of infrared thermal imaging technology. For example, industrial temperature and fire detection, equipment condition monitoring, production process monitoring, fault diagnosis and nondestructive testing. Appraisal of building energy-saving performance and prevention of water leakage, temperature measurement and fire measurement; Security, fire industry monitoring, preventive maintenance, such as the role of explosion-proof thermal imaging camera in airport security inspection and so on. As long as the equipment will heat up before it breaks down, infrared thermal imager has become a very cost-effective and useful diagnostic tool in many applications, which can effectively and accurately detect dangers and prevent dangerous accidents. Explosion-proof thermal imaging camera can avoid the scene where intrusion needs to be prevented in key positions, monitor temperature and fire in real time, and prevent dangerous events.

Second, after understanding the purpose of explosion-proof thermal imaging camera, Bian Xiao takes you to understand the main points of purchasing explosion-proof thermal imaging camera. The most important thing is these four indicators:

First, the detector resolution is generally recommended to be above 160* 120; The resolution is too low and the imaging effect is not very good.

The second scanning format refers to the scanning format of the output image of explosion-proof camera. There are two scanning formats, PAL and NTSC, and PAL is generally used in China. The standard is 625 lines and 25 frames per second (25fps). The United States, Japan and other countries implement the NTSC system (29.97fps). Its size affects the playback speed of the picture.

The third way of temperature measurement: try to choose a model that can automatically capture and move the temperature measuring point and temperature measuring area.

Its four alarm functions, self-checking alarm of explosion-proof thermal imaging camera, are very important. For example, if the tripod head is stuck or the self-inspection is not in place, it will be difficult for the product to play a practical role. If the explosion-proof camera is used in oil fields and mines with extreme environment, it may be MINUS 30 in winter. C the pan/tilt shaft may freeze, and the explosion-proof camera may stop working without self-inspection.

A buhrer Li bispectrum explosion-proof pan-tilt camera (temperature and fire measuring type) is recommended.

Safety and explosion-proof-the equipment has obtained the highest class II explosion-proof grade certification and the highest temperature (T) grade certification, and the explosion-proof mark: EXDIIC T6 GB/EXDA 21IP 68T80; It can be used in the chemical hazardous environment and coal mine in Zone 0, 1 Zone and Zone 2.
