A brief description of explosion proof electronic ruler for explosion proof displacement sensor

Release date: May 22, 2019 Hits: 142
Shenzhen easy measure Electric Co., Ltd. specializes in the research and production of displacement sensor, pull rope sensor, electronic ruler, explosion-proof displacement sensor, explosion-proof electronic ruler, explosion-proof pull rope displacement sensor.

In industrial automation, many sensors mention the concept of explosion-proof. First of all, explosion can be roughly described as the material from one state, after physical or chemical changes, suddenly changes into another state, and releases huge energy. The explosion-proof speed of the sensor is very necessary to meet the conditions of the sharp displacement of the object and the application of the sensor.
  
Similar to explosion-proof displacement sensor, explosion-proof electronic ruler and so on, why explosion-proof? First of all, there are explosive substances in the application place of displacement sensor, and some combustible substances will be produced in many production places. There are explosive substances in two-thirds of the underground coal mines, while in the chemical industry, more than 80% of the production workshops have explosive substances. Oxygen, oxygen in the air is everywhere. The ignition source is that a large number of electrical instruments are used in the production process. All kinds of friction electric sparks, mechanical wear sparks, electrostatic sparks, high temperature and so on are inevitable, especially when the instrument and electrical occur
 
In case of failure, many industrial sites meet the explosion conditions objectively. When the mixed concentration of explosive substance and oxygen is within the explosion limit range, if there is an explosion source, the explosion will occur. Therefore, it is necessary to take explosion-proof, and the displacement sensor also needs to be explosion-proof.
 
It is necessary to identify the explosion-proof mark of displacement sensor, such as flameproof type, to isolate the existing ignition source. Intrinsically safe type is to limit the energy of the ignition source, or the oil filled type indicates that the hazardous substances are separated from the ignition source, and the explosion-proof is applicable to the dangerous places. The explosion-proof mark of the sensor: ex (IA)
 
IIC T6, ex means explosion-proof declaration, which is generally in accordance with certain explosion-proof standards, such as China's national standards. Ex is explosion-proof mark, IA is explosion-proof grade, IIC is gas group, T4 is temperature group. The format of explosion-proof mark refers to the explosion hazardous medium in the factory or mining area,
 
According to the ignition energy, the minimum ignition temperature and the time period of the existence of explosive dangerous gases, the explosion-proof signs and explosion-proof forms of the on-site explosion-proof equipment are determined.
 
The application of displacement sensor in special places needs to be explosion-proof, and the application of pulling rope sensor in special places should also be explosion-proof. It is necessary for the explosion-proof application of sensor in any place that may explode. It is not only in the protection of the sensor, but also an important reminder for people to operate.
 
     
The explosion-proof sensor has reached the highest explosion-proof level in Shenzhen.
