MT1022 Single Point Load Cell
The MT1022 is the ideal solution for retail scales, small platform scales and packaging and process weighing. Due to the low profile the integration into any system is easy. The low capacity range (3 – 30 kg) allows the construction of highly accurate low-capacity scales.
Retail and Bench Scales
MT1022 provides the best weighing performance with such a low profile design. This saves cost in the scale design and makes an attractive low- profile product possible without com- promising on performance.
Off-Center Compensation
One load cell can be used to support a weighing platform and, due to the off- center load compensation, the MT1022 will weigh within tolerance regardless of load application point.
Robustness
MT1022 allows 50% static overload without compromising the weighing performance. The passivated aluminum provides good corrosion resistance suit- able for many industrial applications.
