Smart Load-Cell TechnologyThe load cell, with Monobloc technology, is at the core of the SLF6-Series load cells and guarantees the highest preci-sion 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 ResolutionSLF6 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 PLCAll load cells can easily be connected to popular fieldbus systems. Add-on soft-ware modules facilitate seamless inte-gration into automated environment. This allows machine builders to standardize on SLF6-Series load cells for weighing connected to PLC systems.

SLF6-Series Load CellsAccurate – Reliable – Robust – Versatile

With capacities of 6, 15, 32 and 64 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

Designed for AutomationHigh Precision Load Cells

Hazardous EnvironmentsWhen working in a hazardous environ-ment, 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 gas-eous and dusty environments.
