Hazardous-Area Weighing

Weighing equipment in explosive areas must fulfill stringent regulatory requirements to ensure process safety. However, some safety concepts, can influence weighing performance and make maintenance a challenge. That is why METTLER TOLEDO designs weighing instruments that combine proven safety in hazardous areas with uncompromised weighing accuracy and performance. Approvals for ATEX, FM, IECEx and local regulations ensure regulatory compliance wherever you operate.

Accurate and consistent filling, dosing and batching are essential to ensure consistently high product quality. When choosing the right weighing equipment for hazardous areas, the correct classification and the appropriate method of ignition protection must be considered. Installing intrinsically safe weighing instruments ensures accurate and reliable weighing results at highest protection levels.

Intrinsically safe weighing equipment is ideal for weighing in hazardous areas because it keeps the entire system safe – independent from the weighing application. Intrinsically safe technology prevents explosions by ensuring that the energy transferred to a hazardous area is well below the energy required to initiate an explosion. Intrinsically safe systems allow equipment to be used without risk of igniting any flammable gas, dust or fibers that may be present in hazardous areas.

Intrinsically safe technology provides a flexible and modular solution to most industrial applications within hazardous areas. It is possible to communicate with multiple components through specially designed communication elements. One of its greatest benefits is that intrinsic safety enables equipment maintenance within hazardous areas, without the need to interrupt the power supply and to obtain a gas clearance certificate, which is necessary with open flame-proof equipment. This especially applies to instrumentation because fault finding on de-energized equipment is more complex and time-consuming.

Choose from a wide range of compact, bench and floor scales, load cells, weigh modules and vehicle scales. Our intrinsically safe weighing terminals provide the functionality you need - from manual basic weighing applications to semi- or fully-automated process control. Standard communication interfaces enable seamless integration into your process environment. Furthermore, our products offer the flexibility of mobile battery operation. 

Our experienced, factory trained specialists help you select the right weighing solution that matches your requirements and complies with the relevant hazardous-area regulations. In addition, our comprehensive service program will help you maximize the return on your investments. Keep your equipment operating to the best of its abilities and rely on our qualified support when and where you need it.
