1 Automated Precision Weighing Smart Load-Cell Technology The load cell, with Monobloc technology, is at the core of the SLF6-Series load cells and guarantees the highest precision and reliability. A robust load cell housing features integrated overload protection and durable mechanical interfaces. This ensures stable weight values for many years of intensive use. High Resolution SLF6 load cells have a resolution up to 750`000 points. With this high precision, it is possible to measure even the slightest change in the weight; thus unnecessary waste can be minimized and cost savings realized by optimizing the material quantity. Connect to PLC All load cells can easily be connected to popular fieldbus systems. Add-on software modules facilitate seamless integration into automated environment. This allows machine builders to standardize on SLF6-Series load cells for weighing connected to PLC systems. Hazardous Environments When working in a hazardous environment, safety is key. The SLF6-Series load cells are approved for the use in hazardous areas for Category 2 and Category 3 for top performance in gaseous and dusty environments. Designed for Automation High Precision Load Cells SLF6-Series Load Cells Accurate Reliable Robust Versatile With capacities of 6, 15, 32 and 6 kilograms, it is suitable for a variety of applications and industries. These load cells form a compact solution for integration into machines or instruments, and can support various applications with an industry-leading accuracy. The SLF6-Series load cells provide benefits such as: 750`000 points of resolution Directly connects to control systems Increases speed of filling processes with up to 92 updates per second For safe as well as hazardous areas (Category 2 and Category 3) IP66/IP68 Ingress Protection Minimizes downtimes by checking the platform periodically with the internal weight
