Force: 30kN/90kN, 40kN/120kN

Interface’s 3AR125 3-axis load cell measures forces simultaneously in 3 mutually perpendicular axes: X, Y, and Z – tension and compression. Each axis provides a unique mV/V output and requires no mathematical manipulation. The 3-axis load cell is built to minimize eccentric loading effects and crosstalk between axes. The 3AR Series 3-axis load cell is ideally suited to many industrial and scientific applications, such as aerospace, robotics, automotive and medical research (orthopedics and bio-mechanical). The load cell is provided in various capacity ranges and sizes with each of the three axes providing the same capacity. We are happy to work with your design needs – providing a custom design if warranted for varying capacities (between X, Y, and Z), higher temperature capability, or OEM/private labeling if needed.
