Multi-Axis
3AFM Series 3-Axis Force/Torque Load Cells
Description
Force/Torque: 4.5lbf/0.001lbf-in to 1124lbf/0.57lbf-in
Force/Torque: 20N/0.2Nm to 5000N/100Nm
The 3AFM Series 3-Axis Force/Torque Load Cells are ideal for inspection tasks in quality assurance and material testing due to their compact and low-profile design, with a thickness of just 12–14 mm. This precision force sensor features four independently wired strain gauge measuring springs. The strain gauge signals enable the calculation of axial force (Fz) and bending moments (Mx and My) around the x- and y-axes. Additionally, the sensor’s design allows for the determination of horizontal forces (Fx and Fy) and bending moments based on the distance of the force transmission from the sensor surface. A simple calibration matrix ensures the easy processing of sensor signals, allowing for accurate conversion into forces and moments.
Models 3AFM70 and 3AFM110 are available.
