In the case of flammable and explosive working conditions, considering the safety of the site, it is necessary to choose a pressure transmitter with explosion-proof function. There are three types of explosion protection for pressure transmitters: control of explosive gases, control of explosion confinement, and control of the source of detonation. Control of Explosive Gases: The working principle of the explosion-proof pressure transmitter is to install the pressure transmitter in a sealed explosion-proof box, filled with clean or inert gas that does not contain explosive gases, and keep the air pressure inside the box slightly higher than the air pressure outside the box. Controlled Explosion Limitations: The working principle of this form is to design the explosion-proof pressure transmitter shell as an explosion-proof standard shell, and the explosion-proof pressure transmitter is designed according to the flameproof standard shell, and the process is carried out according to the strict design, manufacture and assembly of all management methods according to the specification, so that the explosion in the shell will not stimulate the explosion of the risk gas outside the shell. The design and manufacturing standards for explosion-proof and explosion-proof methods are extremely stringent, as are the operating procedures for assembly, wiring and maintenance. This method determines that the flameproof electrical equipment and instruments are often very strict, and the operation must be powered off, but it is also the most useful method in many cases. Controlling the Detonating Source: The working principle of this method is to apply the safety barrier for isolation wiring, and the explosion-proof pressure transmitter is processed from the power distribution of the explosion-proof pressure transmitter, and the electrical energy supplied to the explosion-proof pressure transmitter on site is limited to the safe limit that there can be no spark enough to detonate, and the temperature rise of the surface of the instrument can occur enough to detonate. In accordance with international norms and China’s national norms, when any obstacle occurs on the equipment connected to the safety zone of the safety barrier, the substantive safety explosion-proof method ensures the explosion-proof safety of the risk site. When we purchase pressure transmitters, we should choose to use intrinsically safe explosion-proof pressure transmitters and flameproof explosion-proof pressure transmitters according to the differences in use occasions to ensure the safe and effective production of our site.
