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.
