The force sensor K3R70 is suitable for inspection tasks in quality assurance as well as in materials testing because of its compact design.
This precision force sensor is characterized by flat design of only 12 mm thickness.
The axial force Fz and the bending moments Mx and My are calculated from the strain gage signals of the 4 cantilever springs.
With the aid of a simple calibration matrix the forces and distances can be calculated as well.
A key characteristic of 3D force sensors is crosstalk: The application of a force also results in a reading in the two unloaded axes. Due to multiple compensation (mechanical + electrical), crosstalk is typically less than 3% of the nominal load. The crosstalk is reproducible and proportional to the applied force amplitude. By applying an additional compensation matrix, crosstalk can be reduced to typically less than 1% in all axes.
