Multi-Axis Load Cells
Multi-axis load cells are designed and manufactured to measure a multitude of forces and/or moments simultaneously with a single load cell sensor. These sensors provide multiple bridges that precisely measure the applied force from one direction with little or no cross-talk from the other forces or moments when installed and used according to specifications. They are designed to measure force in three directions and torque or moment in three directions. Typical multi-axis load cell applications are found in the offshore industry, industrial test benches and crash testing.
In experimental testing activities, the use of multi axis load cells is widespread e.g. balances for wind tunnels, structures, etc. Many commercially available load cells are able to measure the steady or dynamic forces and moments acting on a structure, but are generally quite expensive and their usage is restricted to advanced research and development activities. The high cost is often due to the relatively complex hardware, to time consuming calibration, and to special materials used for the manufacturing.
