MT1260 Single Point Load Cell
The MT1260 is the ideal solution for floor scales and smaller hoppers. Due to the low profile the integration into any system is easy. The broad capacity range and large platform size allows wide useage in indu-strial weighing applications.
Floor Scale, Tank Weighing
MT1260 provides the best weighing performance for floor scales and hopper weighing in its capacity range. With a low profile design, cost optimization and an attractive product appearance can be achieved.
Off-Center Compensation
One load cell can be used to support a weighing platform and, due to the off-center load compensation, the MT1260 will weigh within tolerance regardless of load application point.
Robustness
MT1260 allows 50% static overload without compromising the weighing performance. The passivated aluminium provides good corrosion resistance suitable for many industrial applications.
