What kind of environment is the explosion-proof detector generally used?

The detector is a kind of detecting device for monitoring human body movement or gas concentration and air pressure change in the environment. Generally, the detecting product has one of various detecting elements such as infrared, temperature sense, smoke, microwave, gas sensitivity, etc. according to different requirements. The detector has two kinds of detecting elements. Depending on the number of detecting elements, the detector can also be divided into three, four, and so on.

When the detector is working, if the environment is in a flammable and explosive environment, an explosion-proof casing is needed to prevent the detector from coming into contact with the outside. This is to prevent the detector from happening due to its own cause. Spontaneous combustion brings a flammable point to the environment.

The flammable and explosive environment also includes places where flammable gas or dust is mixed in the air, such as mines, gas stations, cotton spinning workshops, flour processing plants, ship cabins, etc. For dust sites, it is necessary to install explosion-proof detectors. Consider the following aspects.

1. If the dust itself is flammable (flour, magnesium powder, etc.), an explosion-proof detector must be used.

Second, if the dust itself is non-flammable, it depends on the fineness of the dust particles. Some incombustible substances (iron powder, copper powder, etc.), when the particles are sufficiently fine, are sufficiently contacted with oxygen due to the increased surface area. It is easy to oxidize, so it is also necessary to use an explosion-proof detector.

Third, it is also necessary to pay attention to the existence area and time of the dust. If there is only a small part in the factory that will generate dust, or a small amount of dust will be generated at an individual time in the production process, then the explosion-proof detector may not be installed or only partially installed. detector.

The above is the place to be considered when installing explosion-proof detectors. Most explosion-proof detection products now use explosion-proof double detectors. The explosion-proof double detectors are more accurate than single detectors, and the false alarm rate is greatly reduced. The need for detectors in explosive locations.
