Three actuators are installed on one excavator arm, for the boom, arm, and bucket. Two strain gage rosettes are mounted on each of the thrust tubes, one on the top and one on the bottom. A 6-wire circuit compensates for temperature influences and bending tension. This means that only the relevant axial loads acting directly on the drives are measured. A QuantumX MX410B universal measuring amplifier together with the catman software were used to process the measurement signals.
The installation went smoothly thanks to the detailed guide videos and expert advice from HBM/HBK. The catman software enables the MX410B to connect quickly and easily to the laptop and the strain gages.
