The 3-axis sensor K3D400 is suitable for measuring force in three perpendicular axes. Force is applied onto the 200mm x 200mm platform. A test-specimen can be installed on this surface with four M30 screws. The bottom of the sensor is fixed to the bottom with four M30 screws. The screw-mounting surfaces must end flush with the sensor.

Calibration of 3-Axis Force Sensors – From Standard (cv) to High Precision (s)

A key characteristic of 3D force sensors is crosstalk: applying a force also triggers a measurement in the two unloaded axes. Thanks to several compensation mechanisms (mechanical and electrical), crosstalk is typically less than 3% of the nominal load. Crosstalk is reproducible and proportional to the amplitude of the applied force. By applying an additional compensation matrix, crosstalk in all axes can be reduced to a maximum of less than 1%.

By default, you receive two factory calibrations, each with two measurement points:

one without a compensation matrix (“cv”) and one with extended matrix compensation (“s”).

For detailed proof of the sensor’s linearity, you can optionally extend the calibration to 4 or 6 measurement points:

• Factory calibration certificate HL/4 (4 measurement points)
• Factory calibration certificate SL/6 (6 measurement points)

This ensures your sensor is optimally calibrated to your application from the very first measurement.
