- Measurement performed far from where the force is applied
- Extremely large ratios for nominal forces up to a factor of 50
- Built-in instrumentation amplifier
- Ultra insensitive to lateral forces
Task
Mechanical endurance testing of a truck gear stick involves taking the gear stick through more than several million load cycles in a temperature range of -40 ... +120 °C. The forces exerted in the X- and Y-directions during each gear-change operation are measured continuously by a two-axis load cell and documented by a central data acquisition unit. The effect of any lateral forces in the Z-direction up to 6 times the nominal force is minimized thanks to an extremely robust construction, ensuring long-term stability of the measurement. Significant changes, which might arise from wear or different actuating forces, are analyzed to determine the resultant implications for gear-change performance and durability.
