ATI: F/T System Interfaces (TWE F/T)

Typically used for special OEM and research applications, the TWE (Transducer Without Electronics) system requires customer-supplied amplification and signal conditioning. This system consists of just the transducer, calibration information, and source code. Customers must supply the electrical interface, amplification and signal conditioning according to our documentation. This requires a high level of electronics skill and experience and a complete understanding of the user's manual. Customers must also implement a software interface, but can use ATI supplied code for the necessary calculations.

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.

The ATI Multi-Axis Force/Torque Sensor system measures all six components of force and torque. It consists of a transducer, interface electronics and cabling.

Specifications:

• Output Format: Voltage

• Maximum Output Rate: Practically infinite

• Latency: Negligible

• Filtering Options: None

• Anti-Aliasing Filtering: None

• Thresholding Discrete I/O: None. Thresholding can be custom implemented in user’s software.

• Summary: Fairly easy, most accurate synchronization, computer programming required to access drivers and DAQ card.

• Synchronization Method: Raw transducer signals can be measured together with other signals on the same data acquisition system. (Transducer signal data have to be converted to force and torque data using ATI driver.)

• Latency: Latency between actual event and analog output is a few microseconds. Update rate depends on data acquisition system settings.
