ATI Multi-Axis Force/Torque Sensor

- Measure all six components of force and torque in a compact, rugged transducer

The ATI Multi-Axis Force/Torque Sensor system measures all six components of force and torque. The system consists of a transducer, shielded high-flex cable, and intelligent data acquisition system, Ethernet/DeviceNet interface or F/T controller. Force/Torque sensors are used throughout industry for product testing, robotic assembly, grinding and polishing. In research, our sensors are used in robotic surgery, haptics, rehabilitation, neurology and many other applications.

What is a Six-Axis Force/Torque Transducer?
A device that measures the outputting forces and torques from all three Cartesian coordinates (x, y, and z). A six-axis force/torque transducer is also known as a multi-axis force/torque transducer, multi-axis load cell, F/T sensor, or six-axis load cell.

What is included in a complete F/T System?

A complete F/T system consists of a calibrated sensor/transducer and a system interface.
The sensor measures forces and torques in the X, Y and Z axes. The system interface provides the signal conditioning and communication to the user’s system. Some sensors have interface electronics integrated into the body, while others require external hardware. In order to obtain a quote, a sensor, calibration, and system interface must be specified.

How do I Choose a Sensor?

Model selection is based on:

  • Load Magnitude
  • Size Requirements
  • IP Rating (Environmental Factors)
  • Accuracy & Resolution

How do I Choose the Correct Calibration for My Sensor Model?

To choose the correct calibration, consider the worst-case moment load that will be applied to the sensor. Typically, the moment capacity is the determining factor when choosing the correct sensor model and calibration range. In robotic applications, the worst-case moment load is typically a dynamic load caused by the acceleration of the robotic end effector. For this reason, you will have to consider the speed/power setting of the robot, as the speed/power setting normally determines the maximum acceleration. The loading case below can be used as a worst-case load assumption.
