Explosion-Proof Weighbridge: Safety Guarantee for Hazardous Environments
Application Scenarios
Specifically designed for flammable and explosive environments, suitable for scenarios such as chemical parks, petroleum refineries, dangerous goods warehouses, and fireworks production bases, used for weighing transport vehicles carrying flammable liquids, explosive gases, dust, and other hazardous materials.

Advantages and Disadvantages Analysis
- Advantages: Equipped with explosion-proof certification (e.g., Ex d IIC T6); core components (sensors, instruments, junction boxes) adopt explosion-proof design, which can effectively prevent explosions caused by circuit sparks; good sealing performance, capable of resisting corrosion by corrosive gases; high safety protection level, usually reaching IP67 and above.
- Disadvantages: High manufacturing cost-price is 30%-50% higher than ordinary weighbridges; strict maintenance requirements, requiring professional personnel with explosion-proof qualifications for inspection and repair, resulting in high maintenance costs.
Key Influencing Factors
Explosion-proof grade (matching the corresponding grade according to the type of flammable and explosive substances in the environment), sealing performance, and power supply stability (it is recommended to equip with explosion-proof regulated power supply).
Practical Case
A large petroleum refinery selected a 100-ton explosion-proof weighbridge at the export of finished gasoline transportation. The equipment adopted flameproof sensors and sealed instrument cabinets, passing the national Ex d IIC T6 explosion-proof certification. After putting into use, it successfully avoided potential safety hazards caused by circuit sparks and could operate stably in high-temperature and oil-gas environments. It weighs more than 80 dangerous goods transport vehicles daily with zero safety accidents.
