The 3-axis force sensor K3D120 is suitable for measuring force in three mutually perpendicular axes.

It is ready for 50 N to 5 kN in all three axes and can optionally be manufactured in other measurement ranges.

The force sensor is made of high-strength aluminium alloy up to the 1 kN measurement range. From 1 kN onwards, the force sensor is made from the material stainless steel 1.4542 (option “VA”).

It stands out due to its particularly compact structure, with an area of 120mm x 120mm and a low total height of just 30mm.

Example application areas include force measurement in production processes, force control in handling machines, force measurement in assembly processes, and three-dimensional load measurement.

 

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 SL/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.
