Talking about the data related to strong and explosion-proof monitoring

In order to achieve industrial TV monitoring in a flammable and explosive field environment, explosion-proof cameras and explosion-proof monitoring came into being. Explosion-proof monitoring has also begun to be widely used in various fields. It is worth noting that, unlike the general situation in the electronics industry, the development of China's explosion-proof monitoring is quite early in the international industry in terms of time. As far as the technical level is concerned, it is always no less than similar products abroad.

As far as the explosion-proof field is concerned, China has always been at the forefront of the world in terms of explosion-proof research. The state has formulated a series of explosion-proof standards, which have corresponded with the explosion-proof grade standards of major countries in the world, and many parameters are higher than those of European and American countries; The management is also very strict. For example, after the design review of the explosion-proof product is qualified, the "explosion-proof certificate" and the "production license" that the explosion-proof product must be produced are issued.

Early explosion-proof monitoring was based on intrinsically safe and positive pressure types. Intrinsically safe explosion-proof monitoring is characterized by intrinsically safe handling of the camera's circuitry. The electrical line output or input is designed to be controlled below the energy that would cause the hydrogen to ignite and explode, so that it does not generate sparks during normal operation. , arc and high temperature to avoid detonating explosive materials. The unit cost of this type of explosion-proof camera structure is the biggest disadvantage, and it is not conducive to future upgrades. The positive pressure type is a common structure of early American explosion-proof monitoring products. It is quite inconvenient to maintain in use. If it is not carefully maintained, the risk of detonation is quite large. This structure has been basically eliminated in addition to the fact that a very small number of Taiwanese manufacturers are still manufacturing.

As far as the explosion-proof monitoring itself is concerned, there is no essential difference between the photoelectric structure and the ordinary industrial camera. It is characterized in that the industrial camera is processed by one or more explosion-proof measures, so that it can be applied in a flammable and explosive field environment. Although the explosion-proof type of the explosion-proof electrical appliance is more, it is not suitable for use. Explosion-proof camera. For example, oil-filled type, sand-filled type, etc., can not be used on explosion-proof cameras.
