| | | Strain gauge load cells are available for nominal load capacities from 5 N up to 2000 kN. Together with the digital measurement electronics they have the following advantages: • Automatic identification and acquisition of all load cell settings, calibration parameters via sensor plug.Therefore the change of load cells is very easy and neither requires an input of setting data, nor calibration • Automatic zero and sensitivity alignment • Compensation of temperature fluctuations • High measuring frequency • High test data resolution • Measuring accuracies: Class 1 (1 % of the measured value) from 0.2 to 120 % of the nominal load (1 % to 100 % for load cells with nominal load = 500 N) and class 0.5 (0.5 % of the measured value) from 1 to 100 % of the nominal load • Overload protection | | |
