When both the magnitude and the direction of the load are unknown, the vector measurement is possible using a Strainsert force sensing pin instrumented with two strain-gage bridges oriented 90 apart around the circumference. The cross-section of the pin shows the two sets of strain gages, the Y bridge will sense force component Py, while the X bridge will sense forces in the Px direction, 90 to Py. The outputs from the two bridges, Ex and Ey, can be measured and the resultant force magnitude and direction can be determined (see Biaxial Schematic Image.) *Certain custom pin geometry and bridge to bridge effects (cross-talk) may result in a measurement accuracy of 5% or greater. For such cases, Strainsert can provide a correction algorithm to minimize errors.
