3A Series 3-Axis Force Load Cells

3-Axis Force Measurement

Force: 4.5 lbf to 112K lbf
Force: 10 N to 500 kN

Our 3A Series 3-Axis Force Load Cells measures forces simultaneously in 3 mutually perpendicular axes: X, Y, and Z – tension and compression. Each axis provides a full bridge output and requires no mathematical manipulation. The 3-axis load cell is built to minimize eccentric loading effects and crosstalk between channels.

This 3-axis load cell is ideally suited to many industrial and scientific applications, such as aerospace, robotics, automotive and medical research (orthopedics and biomechanical).

The load cell is provided in various capacity ranges and sizes with each of the three axes providing the same capacity.

Models 3A60A, 3A120, 3A160, 3A300, and 3A400 are available.

BlueDAQ Software

The BlueDAQ software is suitable for live viewing, recording, and analysis of stored measuring data. The multiple channels can be recorded over the time axis (y-t diagram) or via an “X-axis” (X-Y diagram). The BlueDAQ software is available for models BSC1, BSC2, BSC4D, BX6, BX8, and the 9330. The measuring data is stored in binary “TDMS” by recording and can be opened, displayed, and exported in text or Excel format with the integrated “File Monitor”.

SystemLevelCalibration

System Level Calibration

Interface strongly recommends requesting a system-level calibration when purchasing a force measurement sensor with instrumentation. This final step ensures the sensor and instrumentation are properly calibrated and functioning together before leaving Interface.
