Q:Are photosensitive components good with photosensitive resistors or photosensitive diodes?

This should be a photosensitive element, a photosensitive diode is too simple, light and so on, it is not bright flashlight old out, flashlight light. It should be a photosensitive element induction specific spectrum, the sun is a heating body light spectrum and spectrum has the distinction of camping lights, so you can determine the kinds of light and not in the daytime.

Q:What is explosion proof lamp and what is the explosion-proof grade?

2. device classes:The luminaire used in explosive atmospheres is divided into:Class I: explosion proof lighting equipment used in underground coal mines;Class II: Flameproof lighting installations for other explosive gas atmospheres other than coal mines;II flameproof type "d" and intrinsically safe "I" explosion-proof lighting equipment are divided into IIA, IIB, and IIC categories.Flammable dust environment is divided into explosion-proof lighting equipment:A type dust tight equipment; B type dust tight equipment; A type dustproof equipment; B type dustproof equipment.3. Gas GroupThe explosion ability of explosive gas mixture indicates the degree of explosion risk, and the greater the explosion ability of explosive mixture, the higher the risk. The explosive propagation capacity of explosive mixtures can be expressed by the maximum test safety gap. At the same time, the ease of ignition of explosive gases, liquid vapors, and mists is also a sign of the degree of explosion, which is indicated by the minimum ignition current ratio. II type flameproof explosion-proof lighting equipment or safety explosion-proof lighting equipment, according to the maximum experimental safe gap which is suitable for explosive gas mixture or the minimum ignition current is further divided into IIA, IIB and IIC. As shown in table 2.Table 2 Relationship between group of explosive gas mixture and maximum test safety gap or minimum ignition current ratioGas group maximum experimental safe gap MESG (mm) than the minimum ignition current MICRIIAMESG = 0.9MICR>0.8IIB0.9>MESG>0.50.8 = MICR = 0.45IIC0.5 = MESG0.45>MICR

Q:Danger zone should be installed where the explosion-proof lamp, specific to that one

The dangerous area should be equipped with explosion proof lamp, which is stipulated in the safety regulations for explosive dangerous sites.Safety regulations for explosive dangerous sitesGeneral provisionsArticle 1 These Provisions are formulated in accordance with the relevant provisions of the labor law of the People's Republic of China in order to strengthen the safety management of explosive sites and prevent the occurrence of casualty accidents.Article second the term "explosion danger place" as mentioned in these Regulations refers to the place where precautions against the production, use, storage and loading and unloading of explosive materials occur due to the explosion of a mixture.Article third these Provisions apply to enterprises within the territory of People's Republic of China where there is explosive danger.Individual economic organizations are governed by these regulations.Fourth the labor administrative departments of the people's governments at or above the county level shall conduct supervision and inspection of explosive dangerous sites.
