Explosion proof weighing scales are suitable for weighing bulk goods in environments with explosion-proof requirements such as chemical plants, gas stations, and gas stations. The explosion-proof electronic car scale platform produced by Qingdao Simei Weighing Co., Ltd. is manufactured using utility model patent technology, which adopts isolation, voltage reduction, current limiting, sealing, and fiber optic communication technology. By installing various explosion-proof weighing appliances and modules on the platform to form an explosion-proof system, the links in the system that may generate explosive sources (electrical short circuit sparks, electrostatic friction sparks, high-temperature energy concentration, etc.) are eliminated or cut off, So as to achieve the purpose of using the scale in environments with explosive hazards.
