In places that handle hazardous substances, such as chemical plants and pharmaceutical factories, ensuring sufficient safety is essential for establishing a weighing system. To achieve a safe weighing process, we are offering the MetraTredo guidebook "Safe Weighing in Hazardous Locations," which compiles the knowledge you need to keep in mind. ■ Factors and mechanisms that can cause explosions ■ International standards and regulations ■ Various protective structures, including explosion protection ■ Various markings for electrical equipment ■ Inspections required for installation These topics are clearly explained as prerequisites for ensuring safety. Additionally, the book introduces how to construct a safe weighing system, including: ■ Realizing a safe communication network from hazardous to non-hazardous areas ■ Appropriate system configuration examples such as load cells, indicators, and serial communication ■ Appropriate system configuration examples to achieve safe process control You can view the entire content immediately by selecting "Download." Please feel free to contact us with any inquiries regarding intrinsically safe explosion-proof weighing systems or weighing platforms.
