PRODUCT OVERVIEW

Explosion-proof electronic truck scales are suitable for bulk cargo weighing in chemical plants, gas stations, gas stations and other environments with explosion-proof requirements. Weighing Ltd Dalian Horse explosion of electronic truck scale sets utility model patent (patent number: ZL032 84704.1) manufacturing, is the use of isolated, blood pressure, current flow, sealing and optical fiber communications technology, by each of the relevant proof Weighing appliances and explosion-proof weighing modules are installed on the weighing platform to form an explosion-proof system, which can eliminate or cut off the links that may generate explosion sources (electrical short-circuit sparks, electrostatic friction sparks, high-temperature energy concentration, etc.), so that the instrument is in danger of explosion Purpose of the environment.

EXPLOSIVE SUBSTANCE

Explosive substances: Some flammable substances are produced in many production sites.
● Explosive substances are present in about two-thirds of the coal mine underground.
● in the chemical industry, explosive substances are found in more than 80% of the production plant area.
● Oxygen: Oxygen is everywhere in the air.
● Ignition source: A large number of electrical instruments are used in the production process. Various frictional sparks, mechanical wear sparks, static sparks, high temperatures, etc. are inevitable, especially when the instrument and electrical faults occur.
● Objectively, many industrial sites meet explosion conditions. When the mixed concentration of explosive substances and oxygen is within the explosion limit range, an explosion will occur if there is an explosion source. Therefore, it is necessary to adopt explosion-proof. When selecting explosion-proof electrical equipment, it must be noted that the type of explosion-proof is only related to the explosive area, and has nothing to do with the explosive gas level and temperature group. Therefore, for the selection of electrical equipment for specific explosion areas, in addition to selecting the appropriate type of explosion protection, the level and temperature group of the explosive gas must also be considered. Only in this way can we ensure that the selected explosion-proof truck scale meets the requirements of environmental adaptability and safety and reliability.

PRODUCT DESCRIPTION

① MAIN COMPOSITION

MAIN COMPOSITION

● Explosion - proof truck scales are mainly composed of all-steel scales, explosion-proof load cells (ex-protection mark: ExibIICT6 intrinsically safe explosion-proof), explosion-proof special weighing indicators (ex-protection mark: ExibIICT4 flame-proof explosion-proof), and explosion-proof junction boxes Explosion-proof signs are: ExibIICT6 intrinsically safe explosion-proof), and explosion-proof shielded cables (explosion-proof signs: ExibIICT6 intrinsically safe explosion-proof), and optional large-screen displays for explosion-proof (explosion-proof signs: ExibIICT6 intrinsically safe explosion-proof)
● The entire machine (explosion-proof truck weighing platform, explosion-proof dedicated load cell and explosion-proof dedicated weighing display) can be used in places with explosive gas or dust.

Explosion-proof electronic truck scale system, according to customer needs, there are two ways for customers to choose:

TWO WAYS

①FLAMEPROOF CONFIGURATION

FLAMEPROOF CONFIGURATION

● place explosion-proof weighing instruments, explosion-proof sensors, explosion-proof junction boxes in hazardous areas.
② COMPOSITE CONFIGURATION

COMPOSITE CONFIGURATION

● Composite configuration: Place non-explosion-proof weighing instruments in a safe area, and the scale body, sensors, and junction boxes in a dangerous area.

Note: In addition to the explosion-proof means differ, its relevant parameters and technical performance of the SCS are series digital type the same electronic truck.

When selecting the explosion-proof electronic truck scale, users should pay attention to:

PAY ATTENTION TO THE SELECTION

● First determine the hazardous medium and the area where it is used.
● Determine the explosion-proof type, category, level, and temperature group of the instrument in turn.
● Gas explosion protection is completely different from dust explosion protection; coal mine explosion protection is completely different from conventional explosion protection.
● The installation and use of explosion-proof instruments must be carried out in strict accordance with the construction specifications.
● intrinsically safe equipment and non-intrinsically safe equipment must be equipped with related equipment such as safety barriers.

BASIC CONFIGURATION

① INTRINSICALLY SAFE

INTRINSICALLY SAFE

Intrinsically safe type is mostly used on explosion-proof platform scales and explosion-proof small scales,there are three explosion-proof modes: intrinsically safe, flameproof, and composite
● Intrinsically safe type: All components of the electronic weighing instrument adopt intrinsically safe explosion-proof measures, which are suitable for most explosive environments. Intrinsically safe explosion-proof mark. ExibⅡCT4 / T5;
● Explosion-proof type: Some components of the electronic weighing instrument are isolated and explosion-proof by using explosion-proof boxes, but components and interfaces other than explosion-proof boxes still need to be intrinsically safe. Explosion-proof sign: ExiadⅡBT6;
● Composite type: All parts of the electronic weighing instrument are placed in the danger zone, and the other part is placed in the safety zone.Generally, sensors and junction boxes in the hazardous area are of intrinsically safe type, and then connected to ordinary instruments through associated equipment in the safe area. Since this mode operates in a secure zone, its configuration is quite flexible.Composite explosion-proof mark: ExiaⅡCT6;
